Gambling, for sure. Once it's legalized nationally, you won't be able to go 5 seconds at a sporting event (there or on TV) without seeing something from Bet365, William Hill, Ladbrokes, etc. (Other gambling sites are available.)
Cannabis, I'm not as sure about, though. It's been legal in Canada for just over a year now, and I haven't seen a lot of movement in the sponsorship area. Some of it may be that the industry is fairly tightly regulated (so sponsorship may not be legal, I don't know - tobacco companies were banned years ago from sports sponsorship), but the only thing close that I've seen is that a Toronto-based rugby team has a CBD oil company that is owned by the same group as its shirt sponsor.
