Wildfires in Canada’s energy heartland of Alberta have shut down almost 350,000 barrels of daily heavy crude production — about 7% of the country’s output — as a major blaze near the province’s eastern border menaces oil sands operations.

Cenovus Energy Inc., MEG Energy Corp. and Canadian Natural Resources Ltd. are among the companies that curtailed output because of the 61,500 hectare blaze near the Saskatchewan border. The so-called Caribou Lake Wildfire and other out-of-control blazes have grown to at least 10 hectares in size and were within roughly 10 kilometers of about 470,000 barrels a day of oil production early Monday.
