For a few months in 2014 I worked as a non-resident alien under a TN Visa in the U.S. I am a Canadian citizen and resident. I only worked a few months so I shouldn't have to pay much in taxes, but they withdrew taxes anyway. Now I need to file for a refund but I'm not even sure where to start. Resources, contacts to speak to, anything would be helpful.
I also need to report the income to the Canadian government; from what I've read, you're not supposed to be taxed twice, because of a US/Canada treaty.
