If the U.S. is remaking the rules, where does that leave Canada?

The post-WWII rules-based order has been good to Canada. International trade agreements and cooperation have brought peace and prosperity. But with Trump now tearing up the playbook, will we have to follow suit? Or can we find new partners who still want to play the old game the old way? Also, why more North Americans are willing to splurge on business class flights and why long waitlists are pushing Canadians to shop for new hips abroad.
