Ottawa-Gatineau’s annual pace of housing starts in August plummeted 65 per cent compared with July, the Canada Mortgage and Housing Corp. says.
The national housing agency says the region’s seasonally adjusted annual rate of housing starts came in at 6,001 units in August, down from 17,294 in July.
Most of the decline was due to a steep drop in the annual pace of multi-unit starts such as apartments and condos, which fell a whopping 73 per cent to 4,248 last month from 15,540 in July.
