What is Canada Post Flat Rate Boxes?

Canada Post offers its flat rate boxes to businesses and personal shippers across the country. These boxes, which come in three sizes, can be purchased in bulk from any Canada Post office.

For one fee per box, up to a specific weight (5 kg or 11 pounds or about two chihuahuas), you can fit as much as you can inside and send the box anywhere in Canada for the exact same price. Nothing is hidden or added later and you don’t need to guess how much shipping will be. Even your customers will know the exact cost of shipping to get their purchase to them.

Cost and Delivery Time for Canada Post Flat Rate Boxes

Canada Post offers different shipping rates based on the size of the box required.

SizesDimensions (L x W x H in inches)Price
Small10 3/8 x 14 x 2 1/8$17.99
Medium10 3/8 x 15 3/8 x 4 7/8$22.99
Large12 x 16 x 7 1/2$29.99

Depending on where your shipment is going, the delivery time varies. It’s the same though as expected from Regular parcel shipments and letter mail. Flat rate boxes, like letter mail, can be dropped into the red Canada Post mailboxes if needed or can be dropped off at any of the many Canada Post offices across Canada.

The difference between flat rate and letter mail is that you will be required to add stamps based on the weight and size of the box (if it’s not prepaid), which is usually only an estimate and more easily will incur extra costs or be sent back if not properly labeled and stamped.

Why choose Canada Post Flat Rate Boxes for your eCommerce shipping needs?

There are multiple reasons why you may choose to go with the flat rate box option for your eCommerce business.

  • You have no hidden fees. Each shipment costs exactly the same and won’t have costs added if you’re shipping to Vancouver or to St. John’s, Newfoundland. If you normally ship right across the country, then it would be a wise choice to go with Canada Post’s flat rate boxes.
  • Your products fit within the box. If the products you sell and ship fit well into one of the flat rate box sizes, then you can predict that the cost will usually be the same. Of course, if your customer purchases one product, it won’t fill the box, but by promising the same shipping rate up to a certain limit or free shipping over a certain cost, customers will be tempted to add more to their cart.
  • Overall, shipping costs will even out for your business. You will no longer have to pay over $50 shipping to remote areas, etc. The savings on those shipments will balance those that are closer to home but still cost around the same price. Your brand will quickly see the savings add up. If you choose to use Canada Post’s Flat Rate Boxes for your eCommerce business, it is still important to integrate your eCommerce website/platform with an automated shipping software that can instantly fill and print multiple shipping labels to affix to your boxes without any manual data input. You save time and money by partnering with PluginHive.
