I'm not sure if you will be able to find the same brands in Canada as I can buy here.. but the one that I tend to buy is called 'vio life'. It's not 'amazing' but it is just a simple cheese replacement, that if you gave to a dairy eater who didn't know it was non dairy then they would just think it was an uninspired dairy cheese.
I have had some fairly nasty vegan 'cheeses' too though!
The cheese that's used on that pizza is called 'Sheese' - but I haven't tried it on it's own, so I don't know if it is good or not outside of the pizza context ;)
