2018 will be remembered as the year the Canadian housing market cooled by design. The arrival of the B-20 mortgage stress test on January 1, followed by a steady series of Bank of Canada rate hikes, deliberately drained the excess from a market that had been running hot for years. The result was lower sales, moderating prices in the priciest cities, and a sharp regional divergence. As the year closes, this review looks back at what happened and ahead to what 2019 may hold.

OSFI's B-20 stress test began requiring uninsured borrowers to qualify at a higher rate, reducing purchasing power and cooling demand nationwide.
By the numbers
A handful of figures capture the shape of the year: the policy that reset qualification, the rate that framed borrowing costs, and the affordability squeeze that followed.

The year of the stress test
The defining event of 2018 was the expansion of the stress test to uninsured borrowers. By forcing buyers with 20 percent or more down to qualify at a rate roughly two points above their contract rate, it cut effective buying power by an estimated 15 to 20 percent across the country. The impact was felt everywhere but landed hardest in expensive markets where large down payments are the norm. More than any other factor, the stress test set the tone for the entire year.
How the stress test actually works
The mechanics are simple but powerful. Under OSFI's B-20 rules, an uninsured borrower with 20 percent or more down must qualify not at the rate they are actually offered, but at the greater of their contract rate plus two percentage points or the five-year benchmark rate. A buyer approved at a four percent contract rate, for example, must prove they can carry payments as if the rate were six percent. That higher qualifying bar shrinks the maximum loan a household can obtain, which is why the test trimmed effective buying power by an estimated 15 to 20 percent and cooled the market by design rather than by accident.
Verified
OSFI's B-20 stress test took effect January 1, 2018, requiring uninsured borrowers to qualify at the greater of their contract rate plus two percent or the five-year benchmark rate.
Rising rates compounded the effect
The stress test did not act alone. The Bank of Canada raised its policy rate multiple times through 2018, lifting the benchmark to 1.75 percent by year-end. Each hike raised the qualifying bar and increased carrying costs for variable-rate and renewing borrowers. Together, tighter qualification rules and higher rates produced a sustained affordability squeeze that suppressed demand and volumes throughout the year, the double headwind we flagged at the very start of 2018.

GTA stabilized, Vancouver softened
The two largest markets told contrasting stories within the same cooling. The Greater Toronto Area spent the year digesting its 2017 correction and found a floor, ending 2018 stable, quiet, and more negotiable, with condos outperforming detached homes. Vancouver, by contrast, softened further under British Columbia's expanded foreign-buyer tax and new speculation and vacancy tax, with the high-end detached segment leading the decline. Policy shaped both markets, but pushed them in different directions.

Montreal and Ottawa shone
The clear winners of 2018 were Montreal and Ottawa. Both delivered steady sales and firm price growth all year, insulated from the worst of the stress-test drag by their affordability and grounded fundamentals. Montreal in particular emerged as one of the strongest major markets in the country. Their performance underscored the year's central lesson: the 2018 slowdown was concentrated in previously overheated markets, not a uniform national decline.
What buyers and sellers learned
For buyers, 2018 rewarded preparation and patience: a stress-tested budget, a strong financial position, and a willingness to use a cooler market's negotiating room. For sellers, it rewarded realism, pricing to current local conditions rather than 2017 peaks. Above all, the year demonstrated the value of local, data-driven decisions, because national averages masked wildly different realities from one city and neighbourhood to the next. That is the lesson we expect to carry straight into the new year.
The 2019 outlook
Looking ahead, 2019 is likely to extend 2018's themes rather than reverse them. The stress test is now a permanent feature, and further rate moves, though perhaps at a slower pace, remain possible. Expect continued stability in the GTA, ongoing softness in Vancouver as its new taxes fully bite, and steady strength in Montreal and Ottawa. Barring a shift in the rate outlook, the disciplined, regionally divergent market of 2018 should carry into the new year.
Closing the year
2018 was a reset, not a crash. The market adjusted to tighter credit in an orderly way, cooling the excesses of recent years without the disorderly collapse some feared. For qualified, informed buyers it ended as one of the more balanced years in recent memory. As we head into 2019, the enduring takeaway is that clear, local data is the surest guide through a complex market. Helping people navigate that complexity is what we will keep working on in the year to come.
