March 30 (UPI) -- Air Canada announced Monday that its CEO Michael Rousseau would retire by the end of the third quarter after a recent condolences statement given mostly in English.

"The board will consider a number of performance criteria in assessing candidates, including the ability to communicate in French," the airline said in a statement.

On March 22, an Air Canada Express flight from Montreal crashed into an airport fire truck after landing at LaGuardia, killing both pilots and injuring dozens. The two pilots were: First Officer Mackenzie Gunther and Capt. Antoine Forest. Forest was a francophone from Coteau-du-Lac, Quebec.

Rousseau, 68, then issued a 3-minute, 44-second video statement of condolence in English. In the video, the only French he used was "bonjour" and "merci."
