TORONTO — Federal officials are set to say how much more likely Eastern Canada’s heat wave was because of human-caused climate change.

Environment and Climate Change Canada is scheduled to unveil the results of its rapid analysis into last month’s heat wave that enveloped parts of Ontario, Quebec and Atlantic Canada.

It will mark the public debut of Canada’s new rapid extreme weather event attribution pilot program, which officials say can determine whether and to what extent climate change made a specific heat wave more likely or intense.
