According to page two of the small business guide to pst anything brought,shipped or delivered for use in bc gets taxed the pst. If you check the same bc website under business required to register and collect the tax it includes business in other provinces that sell to people in bc. Cra also says Ontario businesses must collect it. But what does the bc government or the cra know about taxation. According to the Khalsa law firm website an Ontario business must register and collect pst if selling goods to people in bc. It took me 30 seconds to google and get this info. But experiences may differ
Finally able to copy from the bc website
From the bc government pst website. You must register to collect and remit PST if you are located outside B.C. (see Location of Your Business below) but within Canada and do all of the following in the ordinary course of your business:
Sell taxable goods to customers in B.C.
Accept orders from customers located in B.C. (including by telephone, mail, email or
Internet) to purchase goods
Deliver the goods you sell to your B.C. customers to locations in B.C. (this includes goods you deliver through a third party, such as a courier)
Solicit persons in B.C. (through advertising or other means, including mail, email, fax, newspaper or the Internet) for orders to purchase goods
