Two families were required to quarantine for 14 days last year after a wrong turn led them across the U.S.-Canada border.

Debra Blackmore was headed to her son’s hockey game in St. Stephen, New Brunswick — a town across the Saint Croix River from Maine — with another family on Dec. 14, 2020, when her GPS incorrectly took her to the border, the CBC reported.

Not wanting to create suspicion by doing a U-turn, Blackmore thought it was best to approach the gate, explain her predicament, and then border agents would let her turn around, the CBC reported.

U.S. border guards gave Blackmore a letter for the Canadian guards saying that the crossing was an accident and sent her back.

However, Blackmore’s vehicle was subjected to a search by Canadian guards before she got turned around, the CBC reported. She didn’t know that entering a building on U.S. soil during the search would have the outcome that it did.

Due to ​​ former federal rules about international travel during the pandemic, travelers entering Canada were required to quarantine for 14 days — even though they didn’t have any symptoms.

As a result, Blackmore and her three passengers — who showed no symptoms of the virus — were required to quarantine.

“We were just doing what the border patrol told us to do,” Blackmore told the CBC. “It didn’t even dawn upon us that quarantine would be an issue.”
