A decision by British voters later this spring to leave the European trade bloc could ultimately make life a lot easier for Canadians — especially for Canadians who don’t want to stay in Canada.

That’s because it would ease the path for a “free labour mobility zone” between the U.K., Canada, Australia and New Zealand.

The U.K. move toward a vote on exiting the European Union is stirring turmoil in foreign-exchange markets and elevating fears for bottom lines in the U.S.

The mobility-zone idea, put forward by London Mayor Boris Johnson, would allow residents of four commonwealth states to live and work in member countries without bureaucratic hassles. Under current EU rules, it is easier for citizens of France, Germany and the other countries in the EU to live and work in the U.K. than it is for citizens of Australia, New Zealand and Canada.

Johnson wrote a column in the Telegraph telling the story of an Australian who has been working in London as a teacher. “She has been told to bog off by the authorities in our country because it was, they said, too much of a palaver to go through the business of ‘sponsoring’ her to stay,” Johnson wrote. The London mayor and Tory MP has also argued that the U.K. could follow Canada’s model of negotiating independent trade agreements with other nations, when and if it leaves the EU.

Polling by the Royal Commonwealth Society released this month showed strong support for the mobility zone, with 75% of Canadians supporting the idea. It was also supported by 70% of Australians, 82% of New Zealanders and 58% of Britons.

A 2009 study found that about 2.7 million Canadians — roughly 8% of them — live abroad.

U.N. data from 2015 showed nearly 750,000 Canadian migrants in the United States, vs. 239,000 U.S. migrants in Canada.
