^ not to nitpick but in your first post you simply mentioned courier, which includes a national courier
Canada Post is always the safest option to go for Canadians, and even then, Canada Post charges brokerage should they have to process your package due to high value. They'll add a $10-15 brokerage fee.
UPS and Fedex charge insane amounts. For BC it's 12% tax + duties + brokerage fee. Avoid avoid avoid.
