Const. RenéDubreuil of Sherbrooke police said the threatening call was placed to the venue’s box office around 6:45 p.m., before Sugar Sammy’s 8 p.m. show.
About a dozen police officers checked in and around the Maurice O’Bready Theatre on the University of Sherbrooke campus before the comedian took the stage.
They were also present in the aisles and near the stage during his performance.
Sugar Sammy filed an official complaint with police, Dubreuil said.
"He was nervous. He didn’t like being in that situation," he said.
Sugar Sammy, who often opines on language during his comedy routines, was most recently in the headlines for having intentionally provoked adverse reaction with his latest ad campaign.
Advertising and marketing firm Sid Lee placed ads in the Montreal Metro promoting Sugar Sammy's upcoming performances with slogans like "For Christmas, I'd like a complaint from the Office de la langue française."
After the show, Sugar Sammy was escorted out of town by police.
