Canada's two new astronauts received a rousing ovation from staff at the Canadian Space Agency on Tuesday as they took questions from children in the audience and toured the facilities.

"I've started new jobs before but I've never ever in my life received this type of a welcome on Day 1,'' Joshua Kutryk of Fort Saskatchewan, Alta., told the gathered crowd in Saint-Hubert, Que.

Kutryk and Calgary's Jennifer Sidey, who will both head to Houston for training next month, were named by Prime Minister Justin Trudeau on Saturday as the country marked its 150th birthday.

Sidey is a lecturer with the University of Cambridge who has worked as a mechanical engineer, while Kutryk is an air force pilot with a bachelor's degree in mechanical engineering and a master's degree in defence studies.

Sidey, who turns 29 in August, says her dreams of becoming an astronaut date back to 1992 when Roberta Bondar went into space aboard the space shuttle Discovery.

'Starting to sink in'

It has been a whirlwind few days and Sidey said she's trying to absorb as much of the experience as she can.

"Things are starting to sink in and coming back to CSA is very special,'' she said.

Jenni Sidey and Joshua Kutryk will begin a two-year training program in Houston this August 5:41

Kutryk, 35, was fascinated with space as a child and said he knew his life would focus on helping to explore it.

The two Canadians will have a two-year training program in Houston along with a dozen new American recruits under the supervision of fellow Canadian astronaut Jeremy Hansen.

"It's adapting to the environment and really settling in so much so that we can learn,'' Sidey said. "Because we need to learn a lot and we need to learn it pretty quickly, so that's a big challenge.''
