Actually, Health Canada has been cracking down on E-juice shipments containing Nicotine that are coming into the country in the last couple months.
If the package is labeled as having nicotine in it, there's a very good chance that it won't make it through customs, and will get sent back to China.
If it's not labeled as having nicotine, there is still a chance it won't make it through, but your odds are better.
I will PM you a list of Canadian suppliers.
Edit: Nevermind, it appears you have your profile set up to not accept PM's.
