A Canadian construction executive and environmental activist who lived in Denver is among the 157 people who died in an Ethiopian Airlines jet crash.

A statement from Edmonton-based PCL Construction says Darcy Belanger was on a personal trip when the plane crashed Sunday shortly after takeoff from Addis Ababa, Ethiopia, en route to Nairobi, Kenya.

The environmental organization Parvati.org says Belanger was an active volunteer for the group that advocates for a protected marine area in the Arctic Ocean.

The organization posted a video of Belanger saying was traveling to Nairobi for a United Nations event, where he planned to meet with government officials.

The organization says Belanger was married.

PCL Construction officials say the 46-year-old Belanger had lived in Denver for two years and was the company’s U.S. director of professional development.
