Summary: If you have capital gains to report for the 2024 tax season, your tax filing deadline has been extended by a little over a month, until June 2, 2025.

Much ink has been spilled about the proposed/delayed/killed changes in the tax treatment of capital gains in Canada. All the fuss simply means that some of us get an extension to our 2024 tax filing deadline. Does it apply to you? It might. Here are some¹ scenarios where you might get a chance to file a bit later.

You Have a Non-Registered Investment Account? Read on.

Some people get confused over capital gains. Capital gains don’t apply to TFSAs, RRSPs, RRIFs, LIRAs or FHSAs. So if that’s all you have for your investments, you don’t need to worry. But if you do have a non-registered account, then the extended deadline may apply to you.

Did you get a T3 or T5 slip? Read on.

Box 21 of the T3 slip and box 18 of the T5 slip shows capital gains realized by funds you held in 2024. If you have values in these boxes, then you can procrastinate!

These boxes will be non-zero if you held ETFs or mutual funds that sold shares behind the scenes and made a profit. My go-to investment asset-allocation ETF (XGRO) made capital gains of nearly 15 cents per unit held², per https://www.blackrock.com/ca/investors/en/literature/tax-information/distribution-characteristics.pdf.

Some people are confused by the idea of having to declare a capital gain on an asset they didn’t touch in the course of the year. While you didn’t do anything, the people who manage the fund on your behalf did. The alternative would be to hold individual stocks yourself, but I myself prefer the massive diversification of funds like XGRO.

Did you SELL an asset in a non-registered account in 2024? Read on.

In many circumstances, the sale of a stock/ETF/mutual fund/foreign currency³ in a non registered account will generate a capital gain. While this scenario doesn’t apply to me in 2024, in 2025 it certainly will since part of my retirement income comes from this exact source.

None of this applies? No extension for you, probably.

If you answered “no” to all the previous questions, then you should file your taxes per the usual deadlines. And even if you answered “yes”, there’s no harm in filing your taxes anyway, since modifying a filed return is pretty easy to do online. Be aware, though, that some providers may delay getting T3s and T5s to you, so if you’re expecting these documents and haven’t seen them yet, you should probably wait for them before attempting to file. The providers I deal with typically don’t issue all documents until the last week of March, so I’ll get started on filing my own taxes starting in April.

1. There are almost certainly other scenarios where you get an extension. I’m not an accountant or a tax lawyer. Caveat emptor. ↩︎
2. In my case, I don’t actually hold XGRO in any non-registered account at the moment. It’s all in RRIFs/TFSAs where I don’t have to worry about such things. ↩︎
3. Interactive Brokers issued me a statement showing me the money I made buying and later selling a chunk of USD in 2024. That counts too. ↩︎
