The flight is scheduled for 2023.
Canada will send an astronaut into lunar orbit for the first time as part of a US mission planned for 2023, Innovation Minister Navdeep Baines said, announcing a formal agreement with Washington.
The goal of Artemis is to send several expeditions to the Moon.
The Canadian astronaut, who has not yet been named, will participate in the second expedition, which is planned to fly around the Moon during a 10-day mission in 2023.
“All eyes will be on the sky when one of our astronauts becomes the first Canadian to fly around the Moon,” Baines said at a news conference.
