Or family visits. My wife and I make frequent trips to the USA to visit family and often with nothing to declare. Nexus lets us breeze through the lines. Love it.
True. However I think most family visits to US usually have overnight stays so most people would want to take advantage of duty free stuff on way back into Canada.
Until Ontario removes the 80 proof alcohol limit in liquor sales, I will always go to duty free store and get cheaper 100 proof or higher from US duty free whenever I stay in US longer than 48 hours
