-The CRA conducts draconian data sweeps for Canadians using PayPal, but in conjunction with the CBSA fails to collect import duty, GST, HST, PST, and Customs Brokerage Fees from international sellers who don't pay a cent of taxes in Canada. In the case of China, Canadian businesses actually subsidize the shipping costs of their competition through Canada Post.
-Walmart was allowed to roll out free shipping in Canada by their other businesses in order to gain market share at the expense of Canadian retailers. Now that Walmart has knocked the competition out of the market, they are charging full price for shipping.
-The privacy office requires opt-in e-mail lists for retailers with extensive compliance requirements. Foreign vendors don't have to worry about complying with these laws so they can create mailing lists for their customers and build a loyal customer base. I can't even e-mail my customers for the past three years to proactively explain what the CRA has done through this court order and that their personal information will not be shared with the CRA.
-CRA allows Amazon (who now have a virtual monopoly over small business e-commerce in Canada) to require Canadians to pay $40 per month to become a pro seller in order to collect GST/HST while Amazon doesn't require this fee in most, if not all other countries that have a VAT/GST tax.
I could go on, but our government (under the leadership of our current and previous PM, this is a non-partisan issue) has repeatedly worked against small business in Canada, the lifeblood of our economy. If you don't call your MP to complain, this trend will continue over the next 5 years with Amazon Canada's 75% growth rate from 2 billion in 2015 to 3.5 billion in 2016 crushing Canadian small businesses.
