The CEO of Air Canada will retire later this year, after being criticized for failing to speak French in a condolence video following last week's fatal collision at LaGuardia Airport that killed two of the airline's pilots. Michael Rousseau informed the airline that he will be stepping down by the end of the company's third quarter, Air Canada said in a statement on Monday. Rousseau had faced calls to resign after delivering his condolences in English only. One of the pilots who died, Antoine Forest, was from French-speaking Quebec. He later apologized and said he was unable to express himself adequately in French - an official language in Canada - despite taking lessons over the years. Announcing his retirement, Rousseau said: It has been my great honour to work with the dedicated and talented people of Air Canada and to represent our outstanding organisation. I look forward to supporting our company during this important transition period. In the same statement, Air Canada noted Rousseau was stepping down after nearly two decades of strong and dedicated leadership with the airline. Rousseau's English-only condolence video was criticized by Canadian politicians, including Prime Minister Mark Carney, who said it showed a lack of compassion. Quebec Premier François Legault also stated that Rousseau should step down if he was unable to speak French. The condolence video was released after an Air Canada plane collided with a fire truck at LaGuardia airport in New York shortly after landing, killing Forest and another pilot, Mackenzie Gunther. Rousseau expressed deepest sorrow for everyone affected in the video, which was posted on X and included both English and French subtitles. He was quickly criticized afterwards for failing to speak French in it and was summoned to Ottawa by Canada's parliamentary committee on Official Languages to explain himself before MPs. He later apologized in a written statement released in both English and French, stating he was deeply saddened his inability to speak French diverted attention from the pilots' grieving families and Air Canada staff. I sincerely apologise for this, but I am continuing my efforts to improve, he said. Rousseau had previously faced scrutiny regarding his French language skills shortly after becoming CEO in 2021, and at that time, he had committed to enhancing his proficiency. Air Canada, originally a federal public corporation, has been private since 1988 but is still subject to Canada's Official Languages Act, necessitating that announcements onboard are made in both official languages.
