The idea of warm destination where Canadians can travel without worrying about Customs or converting their currency to the Yankee dollar would be welcome by many and it would put the Liberals over the top I believe.
There are only 30,000 of them and they are relatively wealthy so the economic burden on Canada would be light. Let them keep their open banking system but require them to give Canada a piece of that action and it would be a wash.
The advantages for them are incalculable.
Make it happen Mr. Trudeau!
