vacancy rate: The CMHC's annual rental market survey found that Ontario, B.C. and Manitoba all saw an increase in vacancy rates, while Quebec, Alberta, Saskatchewan and the Atlantic provinces all saw declines, according to Toronto Star. Stephen Vanhorn / File photo Dreamstime CMHC said demand for rental housing grew at a faster pace than supply. In its annual rental market survey, the housing agency said Wednesday in 2018, the vacancy rate across the country was 2.4 per cent, down from three per cent in 2017. It found that the number of occupied units climbed by 2.5 per cent in October 2018, compared with an increase of 1.9 per cent in the same month a year earlier. The decrease in the vacancy rate was attributable in part to the strong increase in international migration, said Aled ab Iorwerth, CMHC's deputy chief economist. Ontario, B.C. and Manitoba all saw small increases in its vacancy rates, while Quebec, Alberta, Saskatchewan and the Atlantic provinces all saw declines amid steady demand for rental units, the agency said.
