Yeah, that "Bill" rumour has been floating around for years. If you look at the NAFTA list of potential jobs, all require university degrees. That is not issued by the airline, but by the government.
The last time they took pilots from Canada was in the early '80's under strict rules and regulations. I met a retired United skip that did that. He had no regrets.
Go to the US congress web site and look for that Bill and do a search under 'aviation' or 'airline'. You will find that no such Bill has even made the Congress, Senate, nor had a petition filing for it.
Happy Hunting.
