Canada Post has low rates and delivers everywhere in Canada. Through the provisions of the Universal Postal Union Treaty of 1874, Canada Post also delivers everywhere in the world.
To buy Paypal or Shippo shipping labels you will need a Solutions for Small Business number which is free from Canada Post, but you can buy shipping from several private couriers.
If you have a freight forwarder like chitchatexpress near you, you can also have your shipments taken across the border and shipped by USPS.
The only thing you may want to confirm is that the shipper you choose offers Confirmation of Delivery, which you need only in case of an Item Not Received dispute.
