The Alberta wildfires torched the Canadian economy in May, driving the country into its worst one-month performance since the darkest days of the Great Recession seven years ago.
The Insurance Bureau of Canada says damage caused by the wildfires in Fort McMurray totalled $3.58 billion, making it the most expensive disaster for insurers in the country's history.
Residents of Fort McMurray were allowed to return earlier this month, four weeks after a wildfire cut the city in two and forced more than 80,000 residents to flee.
Shell Canada said Tuesday that it had resumed production at its Albian Sands mining operations about 95 kilometres north of Fort McMurray after a seven−day closure.
