Why it matters: This is the fifth extension of border measures first introduced in March as both countries got surges in Covid-19 cases. As Canada coated its epidemiological curve, the US saw caseloads sink in the summer as the disease spread to some regions.
Canadians are more supportive of restrictions, fearing the consequences of American visitors being allowed to drive to popular tourist destinations. The provincial chiefs urged the Trudeau government to continue the measures.
Ottawa was recently closed to a loophole that allowed Americans driving to Alaska to pass through Canada; now, these travelers can only enter five ports of call and must display hang tags indicating that they have been approved to travel to Canada. They should go out on a specific date and check in with border agents as they do so.
