Yep. Just look at the globe and mail. Today they published a hit piece fomenting Alberta separatism. They are owned by the Thomson family. The richest family in Canada. Surprise surprise.

Did some searching online... In the USA, the average salary for a General Practice Physician (according to salary.com) is $234,090 (USD); according to Indeed it's $218,056 (USD) per year. In Canada, the median annual salary for a General Practitioner (GP) is $227,218 (CAD).

So not exactly at par but probably likely still attractive. When you factor in the political climate, I can see how some may choose to move here.
