The arrogance is astounding. You think Britain can cope because Canada does?
What does Canada have that Britain doesn't? well, a massive amount of oil for starters, a growing economy compared to our rapidly shrinking one, and oh yeah, they have trade deals are part of a trading bloc.
Australia, well they masses of land, coal, natural gas, renewable energy sources with the space to build build more, gold, uraniam, copper and of course, bi-lateral trading agreements and they're working on creating a new trade bloc with Canada, the US, Mexico, Chile, Singapore and more. They also have a growing economy compared to our shrinking one.
The US aren't doing so well on the natural resources front but they are the most powerful economy in the world and at the forefront of technological, military and areospace development. And oh, yeah, they have trade agreements too.
What does the UK have? Well, it has a well respected financial services industry which it relies on to keep it's economy
afloat. There'll be no issues at all with the financial services industry if we crash out of the EU with no deal, none whatsoever
