A correction on a 2008 scale
Canada's housing crash is now approaching America's 2008 bust, per BMO.
Canadian home prices have fallen 20.5% nationally from their early-2022 peak, close to the 26% decline the US saw during the 2008 housing crash, according to BMO Capital Markets.
"This is arguably the most significant home price correction ever for Canada, and yet the economy has managed to avoid serious collateral damage from the deep decline," BMO Chief Economist Douglas Porter wrote.
Why Canada has bent instead of breaking
BMO notes the pain, while deep, has been unusually contained. Prices surged roughly 50% in the final two years before the peak, so the correction has hit a relatively small pool of recent buyers hardest.
The decline is also concentrated in two provinces, leaving prices comparatively unscathed across almost half the country.
Canada's real GDP grew at an annualized pace of about 1.7% over the four years since prices began falling, only slightly below this century's 2.0% average, a notable result for such a housing-dependent economy.
Porter cautions that part of that resilience is an illusion: rapid population growth flattered the headline numbers, while real GDP per capita fell more than 2% peak-to-trough during the 2022 to 2023 stretch.
What drove the slide
Variable-rate mortgages reset sharply higher as the Bank of Canada tightened, squeezing heavily indebted households faster than in the US, where long fixed-rate loans dominate.
Investor-owned condos, particularly small units in Toronto and Vancouver, have been another pressure point, and the Bank of Canada has flagged a large stock of unsold small condominiums in both cities.
A slowdown in immigration has added to the drag, removing a key source of housing demand just as a wave of rental supply comes to market.
What it means for the options market
Canadian banks are the most direct trade on whether this stays a correction or becomes a credit event. Mortgage books at Toronto-Dominion and Royal Bank of Canada are the market's main concern, and traders will watch provisions for credit losses each quarter for signs of stress.
Bank of Montreal itself sits on both sides of the story, as the source of the warning and as a lender exposed to the same housing market.
For US traders, the read-across is sentiment rather than direct exposure. Homebuilders like D.R. Horton often move when North American housing headlines worsen, and a deepening Canadian slide could add to caution around rate-sensitive US names even though US price data remains far firmer.
Options flow in the Canadian banks tends to pick up around Bank of Canada decisions and bank earnings, and put activity in TD, RY, and BMO is worth monitoring if price declines accelerate from here.
The bottom line
A 20.5% national decline puts Canada's correction in rare company, even if its banking system has so far absorbed the hit. The next leg depends on rates, immigration, and whether the condo glut clears without forcing distressed sales.
