The federal government has appointed former Mountie Kevin Brosseau as Canada's new "fentanyl czar," a role created as part of a last-minute deal to avert a major trade war with the United States.

Some readers may be surprised to learn that, as an official job title, “czar” is as new to the U.S. as it is to Canada, debuting just this year — brand new Trump appointees David Sacks, the crypto czar, and Tom Homan, the border czar, are the first U.S. officials in history to be formally given the title.
