Most of the small sellers I talk to are paying more to ship than they need to, and it almost always traces back to one habit: they opened a single carrier account on day one and never looked again. Domestic shipping in Canada isn't expensive because the carriers are greedy. It gets expensive the moment you stop shopping around.

Send it ground unless someone's waiting

Speed is the biggest lever on price, so be honest about how fast a package really needs to move. If it doesn't have to arrive tomorrow, send it ground. Canada Post, UPS, FedEx and Purolator all run economy ground services that reach most of the country in two to five business days, often for a fraction of the express rate. A customer who chose standard checkout isn't sitting by the door expecting it overnight — so don't pay as if they are.

No carrier wins every route

Here's the part that trips people up: there is no single "cheapest carrier." There's only the cheapest carrier for this box, to this postal code, today. Canada Post usually comes out ahead on small, light items and on rural or northern addresses where couriers pile on surcharges. The couriers tend to win on heavier parcels and busy lanes like Toronto to Montreal. The only way to actually know is to put the live rates side by side before you buy the label — which is the entire reason rate comparison exists.

Stop paying to ship air

Every carrier bills on dimensional weight, so an oversized box gets charged as if it were heavy no matter what's inside. A 12-kg carton that's mostly bubble wrap can cost more than a snug 14-kg parcel. Keep three or four box sizes on hand, switch to padded mailers for anything soft, and fight the urge to over-pack. Going down one box size is often the difference between two price brackets.

Get off the counter

Walk-up counter rates are the worst deal in shipping. Book the same label through an online account and you'll usually drop onto commercial pricing automatically. Once you're shipping steadily, ask about volume rates — they should improve as your monthly count climbs, not sit frozen where they started.

A few smaller habits that quietly add up:

Drop off instead of booking pickups. Scheduled pickups carry a fee that drop-offs don't.
Batch your day. Print labels in the morning and make one trip, not six.
Re-check your numbers every month or two. A rate that looked great in January can be middling by summer.

None of this is clever, which is sort of the point. Ship ground, compare before you buy, pack tight, and glance at the bill now and then. Sellers who do those four things consistently aren't winning on tricks — they've just stopped overpaying. If you want a number to start from, run a quick quote and see what the same parcel costs across every carrier.
