The latest numbers from the Canadian Real Estate Association help to explain why worries about a bubble are on the rise.

Sales activity in February jumped nearly 40% compared to a year earlier, setting a new record.  Sales rose nearly 7% compared to January.  The national average price surged by 25% year-over-year.  New listings rebounded month-over-month in February but inventories remain at record lows.  Nationally there is just 1.8 months of supply. 

The Bank of Canada has expressed concerns about overheating.  Governor Tiff Macklem has noted that there are signs that real estate speculation is on the rise.

"What we get worried about is when we start to see extrapolative expectations, when we start to see people expecting the kind of unsustainable price rises we've seen recently go on indefinitely, and they're basing their decision on those kinds of assumptions," Macklem warned earlier this month.
