This is not a fair comparison. Russia is built for Religion and its intersection with Culture. Canada is rather about Diplomacy, an aspect of the game which is still relatively ambiguous.
Directly from the Youtube video:
"Canada is built for a strong culture victory and it can make a good run at a diplomatic one as well".
My comparison to Russia is fair. Russia receives faith bonuses from tundra at a much earlier stage in the game. The value over time is exponentially better than ice rink culture bonus which will be later. To make ice rinks good you need a lot of end game civics which do not out weight the Lavra value over time.
Another point. Canada basically gets +1 food from tundra and Russia gets +1 faith/production. I know what yield I would take.
I am really disappointed with how they designed Canada.
