The Alaska loophole has been making headlines in Canada lately, with multiple Americans caught leisurely dining in Banff National Park despite the border being closed to all non-essential travel until at least mid-August.

The loophole allows people from south of the border to enter Canada if they claim to be en route to Alaska.

And fortunately, Canada is cracking down on it.

As of July 31, the Canada Border Service Agency (CBSA) will require all in-transit foreign nationals to enter the country via one of five specified ports of entry:

• Abbotsford-Huntingdon (British Columbia)
• Coutts (Alberta)
• Kingsgate (British Columbia)
• North Portal (Saskatchewan)
• Osoyoos (British Columbia)

Americans will also be required to avoid "all national parks, leisure sites and tourism activities," and to check in with a border agent before leaving Canada once more.

And to take things a step further, CBSA will even require Alaska-bound travellers to hang a tag on their rearview mirror with the date that they must depart Canada, as well as a list of public health measures that they must abide by.

CBSA will also give out a leaflet asking Americans to pay at the pump should they require gas, wear a face mask, and use a drive-thru if they need food while in transit.

The same rules will apply to any foreign national who lands in Alaska and drives down through Canada to reach the U.S.

"These measures are put in place to further reduce the risk of introduction of COVID-19 cases and to minimize the amount of time that in-transit travellers are in Canada," the press release says.

Any travellers that fail to comply with the rules could be slapped with a $750,000 fine and/or imprisoned for six months, in addition to being banned from Canada indefinitely.
