Through 2028, Toronto CMA primary purpose-built rental vacancy (as measured by CMHC's annual October Rental Market Report) stays below 2.5% in all three annual readings (October 2026, 2027, 2028). This is still elevated from the 1.4-1.7% readings of 2022-2024 but far from the balanced-market 3-4% that CMHC considers normalized. The chronic undersupply dominates: new purpose-built rental completions (even with meaningful ramp from Housing Accelerator Fund projects) don't keep pace with net household formation; secondary-market rental (investor condos, secondary suites) shrinks as some investors exit; and the immigration-cut pass-through to rental demand is slower than the pass-through to home ownership. Rental affordability stays severely stressed, with average rents staying well above the CMHC-defined affordability threshold for median renter households.

Crowd 45%Gap 0

By October 2028, Toronto CMA vacancy has risen above 2.5% and the market is detectably loosening. The driver is some combination of: faster-than-projected immigration-cut pass-through to rental demand, a surge in purpose-built rental completions from Housing Accelerator Fund + Build Canada Homes delivery, a secondary-market supply increase as investor condo owners rent rather than sell into a soft ownership market, and interprovincial outmigration from Ontario reducing demand. Rent growth stalls or reverses in parts of the market.

The quiet paththe one nobody’s watching

A secondary-market surge from investor exits could ease rental conditions while the CMHC primary-market vacancy metric still reads tight.

6%
The read
Reality strongly supports Rental Tight (63%); supply-response capacity is below demand-destruction pace.

The purpose-built rental supply ramp from HAF + Build Canada Homes is real but delivery lead times push most impact past 2028. Immigration cuts flow through to rental demand only slowly because the student + TFW cohort continues to re-enter in meaningful numbers.
