If national mortgage rules recently changed or are going to change, it's listed here, all in one place.
Here's the latest on what can affect your mortgage plans today.
A number of new mortgage rule changes have gone from whiteboard to reality — some have been pushed for by the mortgage industry for months or years.
Changes can come from a few places, affecting how traditional banks and lenders treat your mortgage qualification and terms. And they can happen suddenly or be 'proposed' (which may or may not see the light of day).
Usually, the changes address an issue — such as current economic conditions, housing market factors, banking sector concerns, consumer rights, or (even) political pressure.
This blog tracks important recent or proposed changes.
Let's take a look at recent mortgage rule activity.
These changes have either happened or are scheduled to take effect.
AUGUST 1, 2024
Extend to 30-year amortization for first-time buyers of new-builds
The federal government allowed a 30-year extension for first-time buyers only for insured new-build mortgage purchases.
AUGUST 1, 2024
Premium surcharge added to first-timer 30-year extension rule
The premium surcharge added by CMHC is in response to the new 30-year extension rule, which considers the capital impact of these mortgage-length extensions while also supporting CMHC’s mandate to promote housing affordability.

Removal of the OSFI mortgage stress test requirement for straight, stand-alone uninsured renewal switches
This rule removal will help more homeowners find a better deal. The stress-test requirement had already been eliminated for insured switches, as re-emphasized in October 2023 by the then Liberal government in its Canadian Mortgage Charter.
DECEMBER 15, 2024
Insured mortgage changes
These rules aim to help more home buyers enter the real estate market by addressing the current housing market realities of higher home prices and interest rates.
JANUARY 15, 2025
Insured refinances for secondary suites
Insured refinances haven't been available to Canadian homeowners since 2016 (originally removed to discourage the ability to take on more mortgage debt). This new allowance aims to encourage on-the-property density, ideally helping to alleviate the housing and rental supply crunch while offering a potential added (rental) income source for budget-challenged owners.
QUARTER 1 of 2025
LTI cap on uninsured mortgages
OSFI announced in March, 2024, that in Q1 of 2025, banks will have a cap placed on the number of new uninsured mortgages in their portfolio that are more than 4.5 times a borrower's annual gross income (the cap will differ for each lender).
This new rule could impact first-time home buyers the most, shrinking how much home they can buy based on their income (in addition to the TDS ratios already in place) when getting a mortgage approval through a traditional lender.
As rates fall (when and if they do), this regulation has the capacity to reduce single-property homeowners in Canada and favour higher-income earners and property investors, especially in higher-priced markets such as Vancouver and Toronto. (Renewals and refinances aren't included in the lender LTI cap.
OSFI dictates that regulated financial institutions must use the federal mortgage stress test when approving most mortgage applications, such as for buying a home or refinancing. Lenders are able to forego the stress test requirement when approving a straight renewal switch (vs. a refinance) for insured and uninsured mortgages (though not all may choose to do so).
Currently, the mortgage stress-test rate is a minimum of 5.25%, or 2.0% above your contract rate, whichever is higher. Read more here.
In October 2024, OSFI quietly mentioned (in a fireside chat, no less) that the above bankside LTI cap regulation may eventually replace the borrower-side mortgage stress test entirely for uninsured mortgages.
Update May 28, 2025: The evaluation of the LTI limit framework will continue at least until January 2026.

The federal government tables potential budget changes bi-annually. Read through their latest housing measure proposals.
OSFI reviews mortgage rules at least once per year (usually in December), and may propose changes to address current issues or provide forward guidance.
Once it consults with the industry, successful proposals may be formalized, which can take weeks to months to become official, depending on how easily lenders can implement the changes.
The federal government may enact certain mortgage rule changes as part of an election platform or a recent promise. However, doing so without industry consultation (for example, as a move to secure more votes or public favour) can lead to detrimental economic impact.
The banking governance body, OSFI, typically doesn't respond to political pressure — revising or proposing rules based on how it perceives the conditions, needs, or security of the banking industry.
However, OSFI's regulations aren't always popular with all players in the government or mortgage industry, which sometimes leads to feedback and pressure to implement or reverse changes.
It rarely succumbs to that pressure, however. A good example of resisting politics can be seen in OSFI's 'sudden' 2024 mortgage rule change, finally dropping the required stress test on uninsured renewal switches. Despite years of pressure from the mortgage industry and the federal government, OSFI didn't relent until it had its own clear reasons for relaxing this rule due to the economic climate and declining interest rates.

OSFI made no changes to the stress test in 2023. However, it did:
It mulled other changes that didn't go through, such as:
The rules around mortgages are subject to change, and there have been several changes in the past few years, including:
Fact: In 2021, the mortgage stress test minimum was increased to 5.25% (or your contract rate plus 2.0%, whichever is higher) to improve the margin of 'payment safety.' At the time, rates were at historical lows.
"OSFI seems to have an assumption that Canadians will buy as 'much home' as possible," Dan Eisner, True North CEO, observes. "But we haven't really seen that with our clients." From what he sees, Canadians are very diligent about not taking on too much mortgage.
Dan explains further:
"Our True North and THINK Financial clients often come to us with a very good idea of the size of mortgage and payments they can handle. Even if we provide them with higher numbers based on their details, they'll often say, 'This is what I feel I can afford.'
"Canadians, for the most part, aren't going to buy a house unless they feel secure in their jobs and situations. If someone is nervous about their income, they typically don't buy a home until they feel more secure. No one wants that mortgage payment stress, and our clients tend to make relatively prudent decisions to avoid it."
