If "UPS Ground" is the same as "UPS Standard" service, it should be avoided at all costs for shipments to Canada. This is the one that does not include the brokerage fee in the rate. Also, from some of the posts here, there seems to be some confusion about what a brokerage fee is. All delivery methods and all couriers are required to collect GST (federal tax), PST (provincial sales tax) plus any additional duties or tariffs that apply to some product types (usually stuff made outside of the NAFTA zone has a duty on top of the taxes.) On top of these fees, some couriers charge a brokerage fee, which is a fee for filing the import paperwork with the government.
Anyway, because the brokerage fee is not included, UPS Standard service often ends up being more expensive for smaller shipments.
You can see the brokerage fees for UPS at the following table, and see which methods include the brokerage fee in the service:
UPS: Rates for Customs Clearance into Canada
So, for my typical order of $100-$200, UPS Standard would charge me $29 in brokerage on top of the GST, PST, etc.. I can pretty much guarantee NutraPlanet that they will get the highest level of customer dissatisfaction for orders shipped via UPS Standard.
The only shipping method that has any sort of cost advantage is postal mail, as Canada Post usually does not bother collecting duty or even taxes on small value shipments. (Though I can't recall offhand what the dollar amount is.)
These days, pretty much all other couriers include the brokerage fees in their rates. By the way, the DHL service was awesome.
