MONTREAL—Former astronaut and Westmount-Ville-Marie MP Marc Garneau is expected to launch his bid for the Liberal leadership on Wednesday morning, joining an already crowded field.

First elected to the House of Commons in 2008, the 63-year-old was the first Canadian in space and headed the Canadian Space Agency from 2001 to 2005. With two Ontario high schools named after him, Garneau is a party stalwart who serves as the Liberal leader in the House.

With Justin Trudeau widely considered the frontrunner for the top job, Garneau will also face Toronto MP Martha Hall Findlay, B.C. MP Joyce Murray, Toronto lawyer Deborah Coyne, Ottawa lawyer David Bertschi, Vancouver prosecutor Alex Burton and former president of the party’s B.C. wing, David Merner.

In the coming days, at least two other Ontario candidates are expected to announce their intention to run.

The third-place Liberals will choose a successor to interim leader Bob Rae on April 14, 2013 at a leadership convention in Ottawa.

Garneau has been married to his wife Pamela Soame for 16 years, and the couple has two children together. He also has two children from a previous marriage.
