From my experience unless its a vehicle, furs, or alcohol/tobacco you don't deal much with duties, but you will always pay HST if the purchase is over daily limit or whatever the customs agent feels is the limit for that day, have declared $1K on a 15min trip across and was waved thru without paying tax

This. Tax only
