"Jeopardy!" host Alex Trebek is going to be the next host of CBC-TV's "Canada's Next Great Prime Minister."

The game show veteran will lead four ambitious young candidates as they're grilled on political issues by former prime ministers Paul Martin, Brian Mulroney, Kim Campbell and Joe Clark.

They'll be competing for a $50,000 prize and a six-month paid internship with Magna International, The Dominion Institute and The Canada-U.S. Fulbright Program.

A studio audience will vote for the winner.

The one-hour show, previously hosted by comic Rick Mercer, airs March 18.

The final four will be announced online March 11.
