A dive makes sense for Canada's Wonderland because a lot of their current coasters are pretty mediocre so having a dive will give them a good top 3 with Leviathan and Behemoth. Plus it'll be the only dive coaster in Canada so that could break some records there. Canada's Wonderland already has an invert, so I wasn't really surprised to see that they got a dive.
I'm curious to see if we'll see more of these B&M dive machines around the chain as the years progress. California's Great America might get one since they're trying to break 200ft on multiple rides.
