New forecast finds very different paths ahead for high-end and more affordable units

Canada's multifamily vacancy rate is expected to begin trending down in the second half of 2027 as improving absorption outpaces a moderating pace of new deliveries, according to a new forecast from CoStar Group, the leading global provider of online real estate marketplaces, information and analytics in the property markets.

The national multifamily vacancy rate has risen from barely 2% in 2022 to 4.75% today, as net deliveries – which have averaged a consistent 8,000 units per quarter since 2023, roughly double the pace of the five years before the pandemic – have outpaced net absorption despite strong population growth. That national figure, however, masks two very different stories. The vacancy rate for low-end (affordable) units sits at just 3% today, while the rate for higher-end units has jumped from about 7% in 2022 to roughly 15% today, since most new units delivered in recent years have skewed toward the high end.

"When people talk about a shortage of homes in Canada, they are almost always talking about a shortage of affordable homes – there is no shortage of luxury units available," said Mario Lefebvre, Chief Economist for Canada at CoStar Group.

CoStar's new forecast calls for net absorption to begin rising at the end of 2026 – one quarter earlier than in the firm's previous forecast – a trend that may seem surprising given Canada's declining population but is attributable to pent-up demand and declining rent.

"The balance of risks in this forecast remains tilted to the downside," Lefebvre said. "Trade and tariff uncertainty, higher fuel costs, and a declining population could further weigh on the economy and alter expected absorption results. Over the longer term, equilibrium will be restored in the multifamily sector, though the timing will be heavily influenced by future decisions on immigration targets."
