There is no true Canadian bourbon. In reality, only Kentucky bourbon should be called Bourbon. But over the years, somehow, any US Bourbon could hold the appellation (I haven't read how that happened).
I used to (I stopped drinking completely in early 2024) like Scotch or whisky much more than Bourbon, which I usually find way too strong in the mouth. But saying those are piss compared to Bourbon simply means you have no taste at all or you have this blind love for the US stuff only.
The funny thing is some of the best Canadian whisky (12-year Canadian club) is actually aged in Bourbon-based oak barrels, and so are some of Jameson's best Scotch. So you see these makers are not pissing on any other brand and are ready to mix the best to produce the best.
As for wine in America (Canada, US, Chile, Argentina...), most production comes from Europeans who bought land in America (which is next to impossible in Europe) to make production of wine. And they now produce wines on par with European wine. Heck, they simply applied their savoir-faire over here
