The Canadian economy contracted by 0.6% in May as a slowdown in manufacturing and the Alberta wildfire combined for the worst Gross Domestic Product figure since March 2009.

The Fort McMurray wildfire sent oilsands output down 22% for the month, and following an 8.1% drop in April, the output level’s at its lowest since May 2011.

Remove the impact of the wildfire from the equation the economy still would have shrank by about 0.1%.

Bank of Montreal economist Doug Porter says the good news is ”the fall should prove to be a one-month wonder”.
