As a Canadian ESC fan, my answer is no. There's little to no excitement in my country over the contest outside the fan bubble, and I bet not a lot of Canadians even know that Celine Dion participated and won before she became a megastar
Another thing: scheduling. CBC/SRC is the Canadian associate member of the EBU, however their schedules are very much set (Toronto is 6 hours behind CET, so we watch here at 3 in the afternoon). Depending on when the contest proper is scheduled, it could conflict with more important programming such as the NHL playoffs
Omni Television, a multicultural channel on basic cable, did air the show in 2019 (on same day delay) and 2021(semis live, final on delay) - it was supposed to air in 2020 but then the cancellation happened due to the pandemic, then they lost the rights in 2022
