I'm going to try to update this thread with free magazine subscriptions when I come across them.
They are all US only.
Trick to get these free magazine subscriptions in Canada:
1. Have the magazine sent to a US address. It could be a hotel.
2. Wait 6-8 weeks, at the very least.
3. Go to the magazine publisher's website, and login with your existing American address.
4. Change American address to Canadian address.
5. Enjoy your magazine.
If you are asked for occupation, Other/Student usually works.
