“it’s difficult for many landlords when vacancies are high, and the landlords paid high prices for their buildings and have mortgage payments to make,” messier said. landlords can’t afford not to raise their rents when maintenance, heating and other costs are going up, he said.
the cmhc findings on vacancy rates for the most affordable apartments versus expensive apartments reveal two realities.
in the montreal region, the average vacancy rate for the most affordable units under $1,299 per month was 1.5 per cent for 2025, and the vacancy rate for the most expensive units over $1,900 per month was 5.9 per cent.
the availability of apartments on the island also varies greatly by lower- and higher-income neighbourhoods.
for example, the vacancy rate for two-bedroom apartments in downtown montreal and nuns’ island, which the cmhc combines into one sector, was 8.3 per cent this year. it was 4.6 per cent in 2024. by comparison, montreal north had a vacancy rate of 0.9 per cent for two-bedroom apartments this year, compared with 0.1 per cent in 2024.
the overall vacancy rate on the island of montreal alone rose to 3.1 per cent in 2025 from two per cent last year.
there was increased supply of new apartments, while demand for rental units slowed in the montreal region — particularly on the island of montreal – cortellino said, noting that demand was reduced by fewer immigrants, fewer international students and a more difficult labour market for young people.
