The Rick Mercer Report has been a staple on Canada's public broadcaster for 15 years.

But today, the popular host said he's going to call it quits at the end of this season.

"It's still the best job in the world. In many ways, I could do it forever," Mercer told CBC. "But things don't last forever and the shows that I respect the most, they wrap them up on their own terms and that's exactly what I'm doing."

The often amusing program includes segments of Mercer doing wacky things, such as dog sledding and tree climbing, in different parts of the country.

In one episode, Rick Hansen went bungee jumping in his wheelchair in Whistler.

Mercer also includes regular rants that focus public attention on issues that are concerning him.

Over the years, these commentaries have addressed bullying, teen suicide, and Donald Trump, among other topics.

Mercer, an out gay man, also took aim at Stephen Harper and the Conservatives for their approach to same-sex marriage. 

Mercer, 47, was born and raised in St. John's, Newfoundland and Labrador, and has won more than two dozen Gemini Awards for various shows. They've included Made in Canada, This Hour Has 22 Minutes, and Rick Mercer's Talking to Americans.

He's also written three books.
