Medical coverage in Canada for U.S. Resident

I have tried to search for info on this subject but as we long term members know the search engine here isn't especially effective. So, that's why I am starting a new thread.

My wife and I will be vacationing in Canada for about 2 months. Our U.S. Coverage is Medicare with a Blue Shield supplement. Neither gets me coverage in Canada for doctors, hospitalization, etc. I am looking for a med policy probably with a high deductible to make sure that I will be covered in Canada. To all U.S. folks who have purchased short term medical coverage for Canadian travel please let me know the name of the company that wrote the policy. Thanks so much.
