Ken Jennings, the recently crowned greatest Jeopardy! contestant of all time, shared a photo of himself taking a selfie with the host on set, writing: "Alex wasn't just the best ever at what he did. He was also a lovely and deeply decent man, and I'm grateful for every minute I got to spend with him."

Ken Jeong, who shared the screen with Trebek on Hot in Cleveland in 2014, tweeted a photo of the pair, with the caption: "Rest In Peace, Alex Trebek. Sending all my love, thoughts and prayers."

Fellow Canadian, Ryan Reynolds, shared that Trebek had recently filmed a scene in his upcoming movie Free Guy. "Alex Trebek was kind enough to film a cameo for our film Free Guy last year despite his battle. He was gracious and funny. In addition to being curious, stalwart, generous, reassuring and of course, Canadian. We love you, Alex. And always will."

Canadian prime minister, Justin Trudeau shared the impact Trebek had after nearly three decades on TV. "We have lost an icon. Almost every night for more than three decades, Alex Trebek entertained and educated millions around the world, instilling in so many of us a love for trivia," he tweeted. "My deepest condolences to his family, friends, and all who are mourning this tremendous loss."

The PBS children's show Arthur shared a shot of an animated game show host Trebek had once played on the show, writing: "Thank you, Alex Trebek. Elwood City misses you already."
