Jean Charest is not exactly loved in quebec. The end of his provincial premiership was pretty rough and his name is a bit synonymous with "corrupt slimey politician". But I'd bet Québec would still vote for him just because he's from "our team" and he's a very familiar figure
I see a lot of dislike from his past, but I would love to see an older-school politician back in the fray. The CPC needs a strong figure to rebuild.
Charest is a former Huawei employee and a lobbyist for them
