A couple of things about Canada Post really bugs me.
One is when I mail out a package from Alberta to Nova Scotia, the Canada Post started charging me 15% HST. Alberta don't have HST, just 5% GST. When asked about it, I was told that NS has HST and therefore I should pay HST in Alberta when sending mail to NS. If that's the case, why not Nova Scotians are allowed to pay on 5% tax when they send mail to Alberta? (No Answer for it)
2. I mailed a package to UK, and the clerk charged me GST. totaling $15.49. There is no GST when mailing to foreign countries. I went to Canada Post website to check their ruling on GST, and is says: "Mail addressed to Foreign countries requiring shipping charges of $5 or more...are not subject to GST" When I phoned the Canada Post customer service at 1-800-267-1717, the person answered the phone had no clue about the subject.
My understanding is that the Federal government decides on taxes and revisions of tax code. Canada Post is a crown corporation, run by highly paid executives with no sign of intelligence or any respect for the law of the country. They are not authorized to collect HST in Alberta or GST from any Canadians when mailing packages to foreign countries.
Canada Post made it impossible for small business to survive due to their atrocious rates, coupled with volume measurement, fuel surcharge and now this ridiculous illegal tax collecting.
