(Copied from the general forum...)
My teammate Bing recently emailed McMaster to ask about their shipping policy, which they stated as thus:
"We will ship to the University of British Columbia, but we do not ship to individuals in Canada.
If your order is associated with the University, feel free to contact us or place an order by any of the following methods:
We ship to British Columbia in 1-2 days from our Ohio facility. Shipping is based on weight, and we cover any brokerage costs."
(We are ordering through our university).
I am not entirely sure what motivated their decision to stop shipping to Canadian individuals. But consider placing an order through an institution, if you can.
