I still disagree. There’s a lot more cooperation with the US and Canada in Canada on both of those fronts. Small US military contingents train in Canada with our military and vice versa. Furthermore the United States has provided intelligence information multiple time now that have stopped terrorist attempts in Canada. I don’t believe there’s a similar depth of cooperation with the UK — what could the UK even provide to Canada that the US doesn’t already.
Furthermore we’re integrated with the US in ways that we aren’t with the UK, Canadians can stay in the US visa free for six months and when a Canadian enters the US by air they use the US immigration line, whereas UK citizens would not. There’s also freer movement between Canada and the US in that designated professional classes can get NT work visas easy and can be continually renewed with no limitations.
The Canadian UK relationship is just about tradition, and us being polite. At the end of the day, in modern times, countries like Japan or Germany have more sway in Canada simply because we invest and trade more with them. I know some British really want to believe it’s possible to bring back the empire, but it’s really not, Canada is a completely different country now from what it was 80 years ago.
