By Amanda Stephenson CALGARY (Reuters) -Wildfires burning in Canada's oil-producing province of Alberta have affected more than 344,000 barrels per day of oil sands production, or about 7% of the country's overall crude oil output,

The massive wildfire that destroyed part of Fort McMurray in May, 2016, resulted in oil sands production losses as high as one million barrels a day at the height of the disaster. The production outage caused by the wildfire resulted in a 14-per-cent decline of crude oil exports loaded in Alberta.

Wildfires near the Saskatchewan border have prompted Cenovus, MEG and Canadian Natural to scale back operations.
