The Canadian comic icon announced the news in one of his signature rants, posted to Twitter.

“‘Rick Mercer Report’ has evolved over 15 years but one thing that has always remained consistent is that I have always known that I have the best job in the country,” Mercer said. “That has never changed. I can’t tell you how much fun it’s been.”

The “Rick Mercer Report” will air its final, 15th season in spring 2018 on CBC, and will have aired 277 episodes since its launch in 2004.

The show, originally called “Rick Mercer’s Monday Report”, followed the Newfoundland native as he satirized Canadian politics and culture.

“For the past 25 years, Rick has been part of the very fabric of CBC and part of the family in homes across this country, helping us laugh at ourselves and define what it means to be Canadian,” said Heather Conway, Executive-Vice President, English Services, CBC. “Rick has always made us think as much as he has made us laugh, and we can’t thank him enough for his contribution to public broadcasting.”

Over the years, the show has won four Gemini and 12 Canadian Screen Awards, including in 2015 when Mercer won the CSA for Best Performance in a Variety or Sketch Comedy Program or Series.

Mercer’s future is wide open, but right now he’s focused on the upcoming final season of the show. “As far as what’s next, I have no idea,” the 47-year-old said. “All I know is that the entire team is hard at work and we have started shooting what I think will be our best season yet.”

Some on Twitter took the news hard, while other fans thanked Mercer and celebrated his show’s remarkable run.
