If Canada wants to jump on situations like this (attendees can't get in), they should simply stop the grilling of U.S. professionals traveling to Canada for conferences and meetings. Determine and tell Border Patrol that this is not work or a form of work they need to hinder. Make this clear to the public, including the U.S. public. Market the amenities and relative affordability of Canadian venues. And the coincident "tourism" appeal for many U.S. attendees. Profit. I don't know. I don't participate in these things, for many years. But, it seems attractive to me...
