Nonessential travel restrictions from Canada and Mexico do not apply to air, freight rail or sea, and traveling by land is still allowed for many reasons, including business, medical purposes and education. All international air travelers into the United States have to present a negative coronavirus test taken within three days of departure or proof of recovery from the virus within 90 days.
Canada made the decision to reopen its border based on its vaccination progress — more than three quarters of the country has received at least one dose of vaccine, according to governmental data, a far higher percentage than the United States, where a little more than 56 percent of the population has received at least one dose, according to the Centers for Disease Control and Prevention.
Residents within the United States and across its land borders have pressed for reopening, and more than 2,800 people have joined a private Facebook group organized by Let Us Reunite, an advocacy group.
One of the group’s members is Heather Kienle, a U.S. citizen who lives in Montreal. Crossing the border has not been a problem for Ms. Kienle, but her husband, a Canadian, cannot.
So Ms. Kienle, who is six months pregnant, often drives alone or with her 4-year-old daughter more than eight hours to West Babylon, N.Y., to care for her mother, who has endometrial cancer.
“It was just very stressful because I had to travel by myself, without my husband, and I had to take care of my daughter in the back seat,” Ms. Kienle said on Wednesday.
U.S. politicians from both parties have also objected to the restrictions.
Brian Higgins, a congressman who represents a district in Western New York that borders Canada, said in a statement on Wednesday that “today’s decision by the Biden administration harms economic recovery and hurts families all across America’s northern border; this is completely unnecessary.”
