The order does not apply to some US nationals, temporary foreign workers approved by the federal government and other select individuals, including diplomats and flight crews.
"We are extending the existing restrictions on non-US international travel into Canada until 31 October 2020", Blair said via Twitter on Wednesday.
The strict quarantine protocols upon entry in Canada will remain in place. As of 25 March, Quarantine Act violators may be subject to a fine of up to $537,000 and/or a prison sentence in the duration of six months.
In addition, if a violator is found to have contributed to a risk of death of another individual, they can be subject to a fine of up to $720,000 and/or a prison term of three years.
Meanwhile, some Canadians, including parliamentarian Michelle Rempel Garner, have criticized the sweeping travel bans urging the government of Prime Minister Justin Trudeau to introduce exceptions for foreign national partners and adult children.
In mid-March, Prime Minister Justin Trudeau announced that the government is halting the entry of most foreign citizens into Canada.
