You filed months ago. Nothing has arrived, nothing has been explained, and the CRA’s phone line has told you it’s in process.
In our experience the delay almost always comes down to one of five things — and four of them were decided before the envelope was sealed.
1. It went to the wrong processing centre
The least interesting reason, and one of the most common.
GST190, GST191 and GTA rental rebate applications go to the Sudbury Tax Centre. Rental rebate applications for the rest of Ontario and Canada go to Summerside, Prince Edward Island. Send one to the other and you can add four to eight weeks to the timeline.
If you’ve realised your application went to the wrong place, there’s only one thing you can do: send a fresh copy to the correct centre. When the original eventually reaches the right examiner, they’ll see the claim is already in process and file the duplicate.
It feels wrong to send the same application twice. It’s the correct move.
The application wasn’t complete
This is the big one, and it has several parts.
The dates
Rebate forms ask for more than one date, and they are not interchangeable.
The relevant date is the one people get wrong most often. In its simplest form it’s the date you started paying property tax on the property — usually your final closing. You have two years from this date to file. Getting it wrong doesn’t just cause a delay; it can put your claim outside the window.
The date of possession applies to condominium owners. It’s when possession transferred to you, which may not be when ownership did. If both happened together, it’s the same date as the relevant date.
The purchase agreement date should be the last date the agreement was signed, where there are several. Not the first, and not the date the offer was made.
The worksheet, and what the CRA calls white space
If you’re claiming on an owner-built home or a substantial renovation, the GST191-WS worksheet is where most delays originate.
An examiner reviewing that worksheet is asking a simple question: does this look like somebody built a house? They’re looking at how many rows are filled in relative to how many are empty — what we’ve come to call the white space.
Three line items carry disproportionate weight: drywall, plumbing fixtures and flooring. Those values are the clearest indicators that a building was actually completed. A worksheet with substantial spend elsewhere but nothing meaningful against drywall or flooring invites a closer look.
The Business Number
The single most important piece of information on each worksheet line is the vendor’s Business Number — whether there’s one in the box, and whether it’s valid.
Every invoice issued in Canada is supposed to display it. Not every vendor does. Where a BN is missing, an examiner may set out to verify that the business is real, and a large amount with no Business Number against it will be reviewed.
If you’re assembling a worksheet now, chase the missing numbers before you file rather than explaining them afterwards.
The description
Section B asks you to describe the renovation or addition. Applicants routinely write a sentence where a paragraph is needed.
The examiner is trying to understand what was done. Help them. A clear account of what was removed, what was replaced and what remained does more for your claim than most people expect.
Mechanical errors, and the legal description
Arithmetic errors and completed sections that don’t apply to your claim are both common, and there’s no fixing either once the application is with the CRA. If you spot the error soon after filing, send a corrected application — it supersedes the earlier one.
And a specific one worth checking: the legal property description, the lot and plan number. The CRA hasn’t moved to a serial-number system, and an application without a legal description sits until you supply it.
3. The fair market value doesn’t hold up
Fair market value is the value of both the building and the land — broadly, the highest price obtainable between unrelated parties, comparable to similar housing locally. It excludes land transfer tax and any GST/HST payable on the value itself.
For a straightforward new housing claim this is usually uncontroversial.
On a rental property claim it is a trap, and it catches a great many investors.
Here’s the disconnect. At closing, your builder’s solicitor prepares a Statement of Adjustment calculating the HST rebate amount, based on the purchase price. That’s the figure the builder works from.
But when you file your rental property rebate, you have to use the fair market value at closing — which, on a pre-construction purchase bought years earlier, may be considerably higher than what you agreed to pay.
Two consequences. Your actual rebate may be lower than the amount you settled with the builder. And if you file using the builder’s figure, or the price you paid, the CRA will very likely review the claim and adjust the value themselves.
That adjustment takes time. Supplying a sensible current figure at the outset is faster than defending an unrealistic one later.
4. You’ve been selected for review
If an examiner tells you your application is being audited, it usually means it was selected at random rather than because something looked wrong.
Where no further information is needed, expect roughly 30 to 60 days on top of normal processing.
Where the examiner does want more, it takes longer — and how much longer depends largely on how quickly and completely you respond. This is the point at which having assembled the claim properly pays for itself.
5. The right documents weren’t attached
The requirements differ by claim type, and people routinely apply one set to the other.
New housing rebate claims don’t require supporting documents beyond the government forms themselves.
Rental property rebate claims do. You need a copy of the lease showing a minimum one-year term, the Statement of Adjustment your lawyer prepared at closing and the signature page of the Agreement of Purchase and Sale.
Either way, keep everything for seven years — invoices, agreements, the lot. The CRA can ask later, and “I filed it correctly at the time” is not an answer that survives without the paperwork behind it.
One more thing worth knowing right now
The rebate programs changed substantially in 2025 and 2026, and the CRA’s administration has been catching up with legislation that moved quickly.
That means current processing times are not a reliable guide to anything, and a delay today may have nothing to do with your application at all.
It also means the errors above cost more than they used to. When the maximum rebate was $24,000, a four-week delay was an inconvenience. On a claim worth several times that, sitting in a queue because a Business Number was missing is a more expensive mistake.
If it’s been denied rather than delayed
There’s a difference, and it’s worth checking which you’re dealing with.
If you’ve had a notice of assessment denying the claim, that’s not a delay — that’s a decision, and you have 90 days from the date on the notice to file a Notice of Objection.
That deadline is firm, and it doesn’t matter who prepared the original application.
