How Do You Fix a Mistake in an LTB Order in Ontario?

You file a Request to Amend an Order, you have 30 days from the day the order was issued, and it costs nothing. It is the cheapest and least understood of the four ways to challenge a Landlord and Tenant Board order, and it is also the narrowest: it reaches a clerical error and nothing else. If what is wrong with your order is that you disagree with it, this is not the route, and spending your 30 days finding that out will cost you the 15 day window on the route that would have worked.

The short version.

• The power comes from section 21.1 of the Statutory Powers Procedure Act: a tribunal "may at any time correct a typographical error, error of calculation or similar error made in its decision or order".
• The procedure is Rule 24 of the Board's Rules of Procedure, and Rule 24.1 sets the 30 days, running from the date the order or decision is issued.
• There is a form, it is called Request to Amend an Order, and it carries no letter-number designation, so a search for an L form or a T form turns up nothing.
• No fee, for the request or for a late request.
• A clerical error can be the Member's or yours. An error you made on the application that got carried into the order is within it.
• A serious error is not. That is a review, 15 days and $58, and the 15 days runs from the same event as your 30.
• You can ask for a stay while it is decided, and on an eviction order the Board's own guideline says one will generally be issued where submissions or a hearing may be needed.
• An amendment can pull other parts of the order with it, including the termination date and the amounts owing.

We set out the review at the Board in what you can do if you disagree with an LTB order, the court appeal in whether you can appeal an LTB order to the Divisional Court, and the fourth route in whether you can apply for judicial review of an LTB order. This page is the first of the four and the one that gets planned for last, because it is the one you need when the decision is right and the document is wrong.

What counts as a clerical error, and what does not?

A mistake in how the decision got written down, rather than a mistake in the decision.

Nothing defines it. Rule 24 uses the phrase "clerical error" three times, at Rules 24.1, 24.2 and 24.3, and never says what one is. The Statutory Powers Procedure Act, where the power lives, does not use the phrase at all: it names two error types and then extends to a "similar error". The label and the worked examples both come from Interpretation Guideline 15, Amending an Order, which is where the Board sets out its usual approach and which says of the statutory wording, "These are referred to as clerical errors."

Guideline 15 introduces its examples with "A clerical error may include any of the following", so read the four as illustrations rather than as a list. An incorrect name or address. An incorrect date, where "the order sets a date for doing something that is impossible to comply with or is not what the Member intended". An incorrect amount, where "the Member made an arithmetic error or misplaced a decimal point". And an omission, where "The member inadvertently failed to include an essential term or condition in the order".

It then gives four that are not, prefaced with "An error is not clerical if, for example", so this side is illustrative too. It is still the list to read first, because it is where a request gets refused:

• "The name or address on the application is incorrect and the respondent may not have received the application."
• "The error is brought to light by new evidence, or by evidence that was presented at the hearing but overlooked."
• "The member has changed his or her mind on an issue."
• "The error is a serious error."

Read the second and third of those together and you have the boundary. Evidence that was in front of the Member and got overlooked is not a clerical error, even though it produced a wrong result. Neither is a Member who would now decide differently. The line is not how badly the order is wrong. It is whether the wrongness is in the expression or in the decision, and that is our reading of those examples rather than a distinction Guideline 15 draws in those words.

One thing on that list runs the other way, and it works in your favour. Guideline 15 says a clerical error "may be a Board error, or an error made by a party in documentation submitted to the Board that ends up being transcribed into an order or decision". So a unit number you got wrong on your own application, which then appeared in the order, can be within the rule. The guideline attaches two conditions and hedges the result: where the name or address is wrong on the application "but the respondent received it and had an opportunity to participate in the proceeding, the error is likely clerical". Read both halves of that. Receipt is not enough on its own, and "likely" is not a promise. The mirror image is the first exclusion above: if the mistake means the other side may never have received the application, it stops being clerical and becomes something else entirely.

Where does the power to amend actually come from?

A different Act, and the chain is worth following because it explains why the 30 days is softer than it looks.

Start with section 184 (1) of the Residential Tenancies Act, 2006: "The Statutory Powers Procedure Act applies with respect to all proceedings before the Board." Section 184 has two further subsections, both captioned Exception, which switch off subsections 5.1 (2) and 5.1 (3) of that Act for certain applications, and neither reaches anything here.

Then section 21.1 of the Statutory Powers Procedure Act, which is one sentence with no subsections: "A tribunal may at any time correct a typographical error, error of calculation or similar error made in its decision or order." It has been in force since 1995-04-01 and has never been amended. Guideline 15 confirms the attribution in its opening line: "The Board's authority to amend an order comes from section 21.1 of the Statutory Powers Procedure Act."

Three things follow from the wording, and each one matters on a real file.

• The reach is set by similarity. Two named error types, then "similar error", which extends the power by analogy rather than by a list. A wrong legal test is not similar to a typo or a miscalculation, and that is the statutory reason the guideline's exclusions look the way they do.
• The error has to be in the order. The words are "made in its decision or order", so this is about the document rather than about the process that produced it.
• The statute says "at any time". There is no time limit in section 21.1, and none anywhere else in the Statutory Powers Procedure Act attaches to it. The 30 days is set by Rule 24.1, which the Board made under section 176 of the Residential Tenancies Act and section 25.1 of the other Act.

Do not over-read that last point. The 30 days is a procedural limit on your request rather than a limit on the Board's power, which is consistent with Rule 24.2 letting the Board amend on its own initiative with no deadline attached, and with Rule 16.4 contemplating an extension of "any time requirement under the RTA or these Rules". So a late filer is asking the Board to exercise a discretion it has, rather than asking it to do something the statute forbids. That is where the comfort stops. Rule 16.1 does not apply where an extension is prohibited by the Residential Tenancies Act, Rule 16.2 requires the request to come in with the amendment absent exceptional circumstances, and Rule 16.6 gives you one attempt at it. A rule-made deadline is a real deadline, and a late request can simply fail.

It is worth separating section 21.1 from its neighbour while you are here. Section 21.2 is the review power, it lets a tribunal "confirm, vary, suspend or cancel" its decision, and it only operates "if its rules made under section 25.1 deal with the matter". Section 21.1 needs no rule to exist and does not touch the substance of the order. Two powers, one section apart, doing different jobs.

How long do you have, and what is the trigger?

Thirty days, from issuance, which is the same event the review runs from and a different one from the appeal.

Rule 24.1 reads: "A party to an order or any person directly affected by the order may request the LTB to correct a clerical error in an order within 30 days from the date the order or decision is issued." Note who can ask. It is a party to the order or any person directly affected by it, which is wider than the parties named on the application.

Work it on a Brockville file. Suppose the order was issued on Monday 2026-10-05.

• Day one is 2026-10-06 and day thirty is Wednesday 2026-11-04. That is your amendment window. This is a Board deadline, so it is counted under the Board's own Rules, where Rule 1.13 excludes the first day and includes the last and Rule 1.16 says Rules 1.12 to 1.15 may not be waived or varied. It is not counted under the court's rule, which is a different regime, and we set that one out on the appeal page.
• The review window on the same order is 15 days from the same event, so it closes on Tuesday 2026-10-20. The 15 days is statutory, in section 209 (3) of the Residential Tenancies Act, and Rule 26.5 restates it as a Rule for orders issued on or after 2026-07-01, which is what brings the count inside the Board's own counting rules alongside the amendment.

Those two dates are the whole reason this page exists. Both clocks start on the same day and one is half the length of the other. An owner who spends three weeks arguing that a finding was wrong, files an amendment request on day twenty-five, and is told the error is not clerical, has lost the review by a fortnight and can get it back only by asking the Board to extend the deadline under section 209 (3). Diagnose first, then file.

There is one way out of that, and it depends on the answer rather than on you. Rule 26.5 sets the 15 days by reference to "an order or an amended order", so where an amendment is granted and an amended order issues, a fresh 15 days runs from the amended order. Where the request is refused, what you get is a letter or a denial order rather than an amended order, and nothing restarts. So the gamble on a doubtful amendment request is not symmetrical: winning it buys you a new review window, and losing it does not.

The asymmetry is also newer than it looks. The amendment deadline has stayed at 30 days while the review deadline dropped to 15 with effect from 2026-07-01, so guidance written before that date has them both at 30 and is out of date on the shorter one.

What if you are past the 30 days?

You ask for an extension, in writing, at the same time, and you get one attempt at it.

Rule 16 is the extension rule, and its opening words are the gate rather than an afterthought. Rule 16.1 provides that "Except where an extension of time is prohibited by the RTA", the Board "may consider" a request to extend or shorten time for doing anything, if the request is in writing, provides reasons in support of the request, and is filed as required by the Rules. Note the two soft spots. It is a power to consider rather than a power to grant, and it yields to any prohibition in the Residential Tenancies Act.

Rule 16.2 does two things. It names a "request to amend an order" at clause (f) and a request to review at clause (g) as separate items in a list of seven, and it requires the extension request to be filed "together with the motion, application or request". It opens with "Absent exceptional circumstances", so it is a strong default rather than an absolute. Rule 16.3 is the safety net, and it is a conditional one: where an extension is granted and the document was not filed with the request, the Board "will direct that the document be filed, and any filing fee be paid, by a specific date failing which the document will be refused".

Rule 16.4 gives the factors: "the length of the delay, and the reason for it", any prejudice a party may experience, whether that prejudice can be remedied, whether the request is made in good faith, and any other relevant factors. Five things, and the first two are the ones you actually have control over, because they are about your own conduct after you saw the order.

Two further sub-rules carry real consequences. Rule 16.5 lets the Board decide an extension request "without requesting submissions from other parties", so it can be dealt with on your paper alone. And Rule 16.6 is the one that bites: where a request to extend time is denied, you "may not make further requests to extend or shorten the same time requirement, unless there has been a significant change in circumstances". One attempt, and a second one needs a changed world rather than a better argument.

There is a practical trap here that is the Board's rather than yours. The extension form is referred to by three different names across the Board's own material, and the brochure links to two different PDFs for it in two different sections. If you are filing a late amendment request, get the extension form from the same page you get the amendment form from, and do not assume a link in a brochure section about reviews points at the same document.

How do you file it, and is there a form?

There is a form. It carries no number, which is why a search for an L form or a T form turns up nothing.

It is called Request to Amend an Order, it runs to three pages, the version printed on its face is v. 01/04/2022, and it sits under Other Forms rather than with the N, L and T forms. It is listed for both landlords and tenants on the Board's forms page, which gives the filing route as the Tribunals Ontario Portal.

The form is Rule 24.5 turned into fields, and Rule 24.5 is the better checklist if you are drafting anything yourself. A request to amend must be in writing and signed by the person making it, and must include the Board file number, the address of the rental unit, member unit or residential complex, the requestor's name and complete contact information, and must "identify precisely the amendment requested".

That last requirement is the one that decides how fast this goes. Identify precisely means the paragraph, the line and the correct text, not a description of your dissatisfaction. Write out what the order says now and what it should say, and attach the document that proves it, which on a name or address error is the lease or the application and on an arithmetic error is the ledger.

The form also asks whether you have already filed a Request for Review or a Notice of Appeal to Divisional Court. Answer it accurately. Those routes interact. An appeal operates as a stay under section 25 (1) of the Statutory Powers Procedure Act, and the Board's own instructions to the Request to Review an Order say that where an order has been appealed it "is automatically stayed and the LTB cannot consider your Request to Review an Order unless it first decides to lift the stay of the appeal". That is about a review rather than an amendment, but it is the reason the question is on the form.

What does it cost, and how does that compare?

Nothing, and that is the argument for taking it seriously.

The Board's Application and hearing process page states it in terms: "There is no fee to make this request." The brochure Amendments, Reviews and Appeals puts it in the plural, "There is no fee to make these requests", placed so that it covers the extension request as well. Amendment appears in the forms tables on the Board's forms, filing and fees page and in none of its fee tables, which is consistent rather than an omission.

Set that against the other three routes on the same order:

• A request to amend: no fee.
• A request to review: $58, and one attempt.
• An appeal to the Divisional Court: $243 to start and $645 to perfect, on a question of law only.
• A judicial review: the same $243 and $645, plus $339 for the interim order motion you would need to hold enforcement, because that route carries no automatic stay.

On the published fees that is $888 for the appeal and $1,227 for the judicial review against nothing for the amendment. Those figures move when the fee regulation moves, so read the rule rather than memorizing the number, and the Board's fee page also states that "LTB fees are non-refundable."

Who decides it, and will there be a hearing?

The Member who wrote the order, and a hearing is the exception rather than the starting point.

The brochure states it directly, where the other documents only imply it: "A Request to Amend an Order is reviewed by the LTB Member who made the decision." That is worth knowing before you write it, because the reader of your request is the person whose order you are saying is wrong, and a request that identifies a line and a figure will land better than one that relitigates the hearing.

Guideline 15 sets out how it can go. Where the Member "determines there is an obvious clerical error that should be corrected, and the amendment will not cause prejudice to the other party", the order may be amended without seeking submissions at all, and the guideline adds that the Member "can also make any consequential amendments without seeking submissions". Where a party may be prejudiced, the Member "may invite submissions or hold a hearing", and the guideline says a direction letter should enclose your request and give the parties a period to respond, adding that "Generally a period of 10 to 15 days will be sufficient". Where submissions come in, the Member may decide on the paper without a hearing.

If it is refused, what you get depends on how far it went. Guideline 15 says that where the Member determines there is no clerical error, a letter goes to the party who asked. Where the request is denied after a hearing, "an order will be issued explaining why the request to amend has been denied".

Rule 24.2 is the other way this happens, and it needs nothing from you: the Board "may amend an order to correct a clerical error on its own initiative without seeking submissions from the parties or holding a hearing". A slip you have noticed may already be in hand.

Can you stop the order being enforced while you wait?

You can ask, and on an eviction order you should.

Rule 24.6 is the route: a party may ask the Board to stay its order pending a decision on the request to amend, and "the request to stay must be in writing and identify the prejudice the party will experience if the order is not stayed". Read the second half as an instruction. The prejudice is the content of the request, so say what happens if the order is carried out before the error is fixed.

Rule 24.4 is the Board's own version, and it runs both ways: on its own initiative the Board may stay an order pending the resolution of a request to amend, "or revoke a stay at any time", without submissions or a hearing.

Guideline 15 says when to expect one. A stay "will not always be necessary", but "where the request to amend concerns an alleged error in an eviction order, and the Member determines that it may be necessary to seek submissions or hold a hearing, a stay will generally be issued", and a stay may also be issued where the request arrives close to the effective date of the order. The stay comes as an interim order, and the guideline is precise about its end: if the request is denied, an order must issue lifting the stay, and if it is granted, the stay is lifted in the amended order.

One caution on what a stay does. A stay pauses enforcement of the order; it does not decide anything, and the arrears or the termination date it pauses are still there when it lifts.

What does an amended order actually change?

More than the line you asked about, which is the part worth planning for.

Rule 24.3 provides that if an order is amended to correct a clerical error, the Board "may also amend or update other provisions of the order as necessary". Guideline 15 explains the idea: an amendment to one part "may require an amendment to another part", and in some cases it may be necessary to update the order "to reflect any amounts that have been paid or have become owing since the original order was issued".

The form is more concrete than either, and it is the sentence to read before you file: where an order is amended to correct a clerical error, "amendments may also have to be made to other parts of the order, such as the termination date and/or any amounts owing".

So a corrected arithmetic error does not simply reduce or increase one figure. It can move the termination date and it can refresh the balance to the date of the amended order. Guideline 15 says the amended order will explain "why the order is being changed and what the changes are, including any consequential amendments", and the brochure adds that the amended order "replaces the original order". Read the amended order end to end when it arrives rather than checking only the line you complained about.

What if the problem is not clerical?

Then it is one of the other three, and the guideline draws that line harder than anything else on it.

Guideline 15 says: "A member cannot amend an order to correct a serious error. A serious error can only be corrected by way of review under Rule 26 and Guideline 8." It also sets out what happens if the Member thinks that is what they are looking at: they may deny the request to amend "if the order does not contain a clerical error", or "in exceptional cases, refer the matter to the Vice Chair who can initiate a review of the order".

Do not treat that referral as a plan. It is described as exceptional, it is somebody else's discretion, and it does not stop your own 15 days running.

So match the problem to the instrument before you file anything:

• A misspelled name, a wrong unit number, a date that cannot be complied with, a misplaced decimal, an omitted term. Amendment, 30 days from issuance, no fee.
• A decision driven by a serious error. Review at the Board, 15 days from issuance, $58, one attempt, and it reaches the facts, because paragraph 2 of section 1 (3) of O. Reg. 178/26 makes "an error of law, fact or mixed fact and law" a ground.
• A misapplied legal test you want a court to rule on. Appeal to the Divisional Court, 30 days from being given the order. It operates as a stay under section 25 (1) of the Statutory Powers Procedure Act, though that subsection carries two exceptions and the stay is the default rather than an absolute.
• A finding with no evidence at all behind it. Judicial review, 30 days from the day the decision was made, under section 5 (1) of the Judicial Review Procedure Act, and with no automatic stay, because section 25 (2) says an application for judicial review "is not an appeal within the meaning of subsection (1)".

Two of those four run from issuance and two do not, which is why the first thing to write down is both dates.

Does any of this change for a co-op, a park, a work order or social housing?

No, and the reason is that the power is not in the Residential Tenancies Act at all.

Section 21.1 of the Statutory Powers Procedure Act applies to the Board's orders because section 184 (1) makes that Act apply to all proceedings before the Board, and the exemption machinery in the Residential Tenancies Act works by disapplying named sections of itself. Three checks bear that out. Section 7 (1) disapplies a long list of provisions from social housing, and nothing here is on it, because nothing here is in that Act. Part X, the mobile home park and land lease community rules, runs from section 152 to section 167 and touches none of it. And on a non-profit housing co-operative under Part V.1, section 94.16 maps provisions across with necessary modifications because they are drafted around tenants and landlords, which section 21.1 is not.

The Rules and the form go further and name the co-operative case directly. Rule 24.5 requires "the address of the rental unit, member unit or residential complex", and the form's first part offers Co-op and Co-op Member as requestor types alongside Landlord and Tenant. So a co-op or a member uses the same route and the same form.

The work order case is worth naming because it looks different and is not. A landlord's review of an inspector's work order under section 226 ends in an order of the Board like any other, so it can be amended on the same 30 days for the same clerical errors. We go through that route in what to do if you get a work order on an Ontario rental property. The municipal property standards order sitting behind it is a different instrument and none of this reaches it.

One caution about the guideline itself, since this page leans on it. Guideline 15 carries a bare date of 2018-12-15, with no effective or updated label, and the Rules it explains now print an effective date of 2021-09-01 and an update of 2026-07-01. Its cross-reference to the review rule predates the current grounds and the current 15 day deadline. The disclaimer printed on its face is the right way to read it: guidelines are "intended to assist the parties in understanding the Board's usual interpretation of the law", and "a Member is not required to follow a Guideline and may make a different decision depending on the facts of the case".

What should you do the day the order arrives?

Two dates and one diagnosis, before you write anything.

• Write down the date printed on the order as the date of issuance, and the date you were actually given it. The amendment and the review both run from the first. The appeal runs from the second, and the second will not be reconstructable later.
• Read the order against the application and against your own records, line by line, in the first few days rather than the last few. Names, the unit number, every date, every figure, and whether any term the Member said at the hearing is missing from the document.
• Decide which of the four you are on. If the answer is that the order says the wrong thing, it is an amendment. If the answer is that the order decided the wrong thing, it is a review, and you have 15 days rather than 30.
• If it is an amendment, identify the correction precisely and attach the proof. Rule 24.5 requires you to "identify precisely the amendment requested", and a request that quotes the line and gives the correct text can be granted without submissions.
• If the order evicts anybody and you are asking for an amendment, ask for a stay under Rule 24.6 in the same document, and say what the prejudice is.
• If you are past 30 days, file the extension request together with the amendment request, and remember Rule 16.6 gives you one attempt.
• Expect the amended order to move more than the line you raised, and read all of it.

One thing to hear plainly. An amended order is not money and it is not a win. It corrects what the order says, and if the order said you were owed an amount, the amendment is at best the document you needed before you could collect it. That is worth weighing against the amount in dispute before anybody files anything, and it is the reason this route is worth using quickly and cheaply rather than treated as a second hearing.

Should you handle this yourself or hand it to a manager?

This one you can run yourself, and it is the only one of the four we would say that about.

A request to amend is a signed letter or a three page form, on a 30 day window, with no fee, and capable of being decided on the paper by the Member who wrote the order. Rule 24.5 tells you exactly what it has to contain. An owner with one or two units who reads the order carefully in the first week can do this without help, and doing it quickly is worth more than doing it elegantly.

What needs judgment is the step before it, which is deciding whether the error is clerical at all. Get that wrong in the direction of an amendment and you lose the review window. Get it wrong in the direction of a review and you have spent $58 and your one attempt on something the Board would have fixed for nothing.

Where KEILTY earns its keep on a file like this is earlier again. A clerical error that reaches an order was often already in the application, and the ones that hurt are the unit number, the name on the tenancy agreement and the arrears arithmetic. A file where the ledger is dated, the notices were served with proof of service and the application was checked against the lease before it went in is a file where the order comes out right the first time. If you own a building and it is being run off the side of a desk, our small multi-family page sets out how we run it.
