Simplify your shipping
Flat rate envelopes
Send important documents, small products and standard-sized packages with our flat rate envelopes to manage your costs and save time.
Flat rate boxes
Send larger items anywhere in Canada with our flat rate boxes. The price of postage, tracking and liability coverage are included in the cost of the box. They are available in three sizes and can hold up to 5 kg. If it fits, it ships.
Flat rate service regionsFlat rate products can be sent regionally or nationally.
If you want to send your items between two points within the same region (e.g., Vancouver to Winnipeg), then you’ll need regional service.
If you want to send your items between two different regions (e.g., Vancouver to Halifax), you’ll need national service.
