What have you done for medical insurance while traveling in Canada? I am retired military and have Tricare and closing in on Medicare. From what I understand neither are accepted in Canada.
I would call Tri-Care and talk to a rep. In 2012 while traveling to Alaska I developed a severe sore throat and visited a clinic mostly to make sure it was not strep! Anyhow, I had to pay the bill, when I got home I filed with Tricare and they did reemburse me about 40%.
