Do get your extra post in quick if you want to make it this hour!
If you've been reading in the Canada forum, I'm sure you realize how bizarre that situation is. I've been trying to follow many of the national forums, but Canada is the one that confuses me the most! HC "doesn't approve" of e-liquids with nicotine, and although that is not legal justification for customs to reject them, they do nonetheless. Yet nic e-liquids are freely for sale in Canada?
Is there a dollar limit below what you need to declare when going through customs? If so, just stay below that limit.
Can you get concentrated nic in Canada? If so, by 0mg liquids, and add Canadian nic once you get back home.
And will Canada actually revoke your right to re-enter the country if you have problems at the border? Not sure I can see how they could (been several years since I visited, but when I did you went through US customs on the way to the US, and Canadian customs going to Canada. So you could go to the US (since US customs wouldn't give a damn) but then as a Canadian citizen they wouldn't let you back into Canada? Not a likely scenario, IMHO. But perhaps Canada is even weirder than I thought.....
