The move - effective July 5 - is a first, incremental step to ease restrictions amid mounting impatience for the government to reopen the border between the US and Canada.
According to officials speaking during a technical briefing on background, those entering will need to show documents proving they received doses of the vaccines approved in Canada at least 14 days prior to entering the country.
Following the announcement from the Canadian government Friday, Congressman Brian Higgins, who serves as co-chair of the Canada-U.S. Interparliamentary Group, used an expletive in describing the border closure extension.

Hajdu was tight-lipped Monday on what would be required before Canada moved to the second phase of border reopening, saying simply the decision would be based on metrics like case rates and vaccination domestically, and the progression of COVID-19, notably the delta variant, internationally. This is the first step towards a vaccination passport, and the onus of using a digital program prompted questions to officials about the potential limitations this poses for those who are unable to utilize the technology.
"Clearly, as those vaccines arrive and as Canadians continue to get in those lines and get vaccines into their arms, we're really optimistic that we can meet that threshold of 75 per cent", he said.
