Brokerage fees and taxes are the buyer's responsbility.
Any time you import items into the country they can be assessed and taxed. If your shipment arrives with UPS, expect a large brokerage fees and taxes due.
If your shipment arrives Canada Post, taxes and a $10 flat rate handling fee may be due.
Anything valued at more than $20 can be taxed....UPS pretty much gets you every time. Canada Post is hit and miss.
I avoid sellers who ship UPS into Canada and I always count on taxes when importing. I'm usually happily surprised that it doesn't happen but prepared when it does.
