Border crossings are expected to be extremely busy Monday as Canadians head home after visiting the United States over the long weekend.
INDEPTH: The soaring Canadian dollar
The high Canadian dollar, combined with the Victoria Day holiday, added up to a busy border this weekend, officials said.
At one border crossing in Manitoba, people waited at least an hour to get into the U.S. on Saturday morning.
Loretta Nyhus, a spokeswoman for the Canada Border Services Agency, said people returning to Canada can expect similar delays.
"They were backed up into Canada, so we're expecting the same number of vehicles on the way back," she said.
People heading home are advised to have all their receipts and documentation ready when they reach the border, she said.
"It is going to be a busy time, I think, for the staff down there, and we will have all the lanes open. So we're trying to get everyone through as quickly as possible," she said.
A few years ago, the loonie was worth only about 65 cents in U.S. currency and cross-border shopping became a less attractive option for Canadians.
However, in recent weeks Canada's currency has surged to levels not seen for decades. It's currently riding just below 90 cents US, which has boosted buying power south of the border.
