CMHC Cuts Housing Forecast as Tariff Uncertainty and Toronto's First Population Drop in Decades Collide
Statistics Canada confirmed something most Toronto residents already sensed: over 60,000 people left the metro area for other parts of Ontario in the most recent reporting cycle, marking the first sustained population outflow in decades. The same week, CMHC revised its 2026 housing start projections downward, blaming tariff-linked construction costs that are now eating into whatever relief recent interest rate cuts might have delivered.
The timing matters. Lower borrowing costs usually signal a construction upswing, developers borrow cheaper, buyers stretch further, starts climb. That relationship is breaking down. The Industrial Product Price Index for lumber and other sawmill products remains volatile, driven largely by Canada-U.S. softwood disputes that predate the current administration but have sharpened under proposed steel and timber tariffs. What was supposed to be a rate-cut recovery is instead becoming a lesson in how supply-side inflation can neutralize monetary policy.
CMHC's analysts frame the problem as embedded inflation. The federal government waived GST on purpose-built rentals to spur multi-unit construction. Developers absorbed the savings and still shelved projects, because the tariff impact on imported materials, steel rebar, engineered wood, even fasteners, wiped out the tax break and then some. In the Greater Toronto Area, new rental starts in 2026 are running below the 2024 peak despite financing conditions improving month over month.
Why people are leaving instead of waiting
The exodus from Toronto is not a collapse. International immigration still flows into the region, keeping the total population relatively stable. But the net outflow of current residents is new, and it correlates with a specific income bracket: mid-career professionals who can work remotely and who watched their renewal notices jump from 1.79 percent five-year fixed in 2021 to mid-4 percent this year. They are not moving because Toronto lacks jobs. They are moving because a detached home in London, Ontario, or a new build in Edmonton costs 40 percent less and their employer no longer requires them at a downtown desk.
This creates a feedback loop CMHC's models do not fully capture. When high earners leave, they take their housing demand with them, but they also reduce the buyer pool for new luxury condos that were pre-sold assuming 2021-style incomes would persist. Developers adjust by building less, which keeps prices high for whatever stock remains, which accelerates the next wave of departures.
The variable-rate gamble returns
Mortgage brokers report a surge in variable-rate inquiries for the first time since 2023. The spread between the lowest insured 5-year fixed (currently low-to-mid 4 percent) and variable products has tightened enough that borrowers are willing to bet the Bank of Canada will cut further. The calculation is straightforward: if you believe the overnight rate will settle between 2.75 and 3.25 percent by late 2027, locking in today at 4.4 percent fixed costs you roughly $18,000 in unnecessary interest on a $500,000 mortgage over five years.
The tariff overhang complicates that bet. Trade volatility feeds into the inflation figures the Bank watches, which could slow or reverse the easing cycle. A borrower choosing variable today is effectively wagering that diplomatic resolution on softwood and steel happens faster than CMHC expects. It is not a mortgage decision. It is a trade-policy forecast with a quarter-million-dollar stake.
The agency's dampened outlook for 2026 starts assumes current tariff structures hold. If they escalate, the floor for construction costs rises further, and the supply deficit persists regardless of how low rates go. If they resolve, the rebound could be sharp, but resolution is not something housing economists can model with confidence when the negotiating table keeps shifting.
Toronto's shrinking footprint and CMHC's revised numbers are symptoms of the same structural bind: monetary tools work when the constraint is demand, not when it is the cost of two-by-fours and the fact that buyers are walking away entirely.
