More & more Canadians are packing overnight bags for roadtrips to the US.

Statistics Canada says the number of overnight cross-border trips to the states jumped 7.5% in June to the highest level since 1972.

Most of those overnight trips were by car.

It isn't clear if new cross-border shopping rules that kicked in June 1st had anything to do with the spike.

Now, after a 24-hour stay, you can bring back $200 worth of stuff duty-free.  If you stay at least 48 hours, the maximum is $800.  There still aren't any exemptions for same-day trips.

Some local businesses & economists predicted the change would hurt Niagara retailers.

The number of trips to Canada grew a little in June, up 0.5%.
