Canada Post vs UniUni

Where each one delivers

Canada Post says it delivers to every residential and business address in Canada. That includes PO boxes, general delivery, rural mailboxes and the territories, where northern and remote points take 5 to 14 business days.

UniUni is a last-mile company built for e-commerce parcels going to homes. It says it reaches 80% of Canada, and its coverage map shades all ten provinces and marks Yukon, the Northwest Territories and Nunavut as not yet covered. It delivers to street addresses only, never to PO boxes or post offices, and it doesn’t say in words which rural areas it covers. Some UniUni parcels are handed to Canada Post for the last leg, and the tracking then shows a transfer. A ProtonShip quote only shows UniUni when it serves both ends of the route.

Delivery times

Canada Post publishes delivery standards. Between major urban areas, Regular Parcel takes one to three business days locally, three to six regionally and four to ten nationally. Expedited Parcel takes one to two, one to four and two to eight days, Xpresspost next day, next day and two days, and Priority next day. The On-Time Delivery Guarantee covers all of them except Regular Parcel. Canada Post delivers Monday to Friday, and weekend delivery is starting in parts of Toronto, Ottawa and Montreal.

UniUni describes its range as “from next-day delivery to up to 7 days” and publishes no zones or transit chart. It advertises seven-day service in major metropolitan areas but gives no weekend schedule or delivery hours. In a ProtonShip quote, UniUni’s own delivery date appears when it gives one, and otherwise the estimate counts business days.

Size and weight

Canada Post publishes its limits: 30 kg (66 lb), 2 m (78 in) on the longest side and 3 m (118 in) in length plus girth, with dimensional weight at 166 for Regular Parcel and 139 for its other services. A 12 × 9 × 4 inch box that weighs 2 lb comes to 2.6 lb by Regular Parcel and 3.1 lb by the faster services.

UniUni says its network is optimized for parcels of 10 lb or less, and it doesn’t publish one set of limits for business shipments. Its terms for sellers who ship with UniUni directly allow up to 60 lb and 80 inches for the three sides added together. UniUni doesn’t publish how it works out dimensional weight either, so a ProtonShip quote asks UniUni about each parcel and shows UniUni’s own price.

Signatures and proof of delivery

Canada Post offers a signature option. UniUni drivers take photos at the drop-off as proof of delivery. UniUni sells a PIN or signature check on its own platform, but it isn’t offered through ProtonShip, and UniUni drops out of a quote when you ask for a signature.

Both lean on those photos when a parcel goes missing. Canada Post won’t pay a loss claim when a photo shows the parcel delivered, and UniUni won’t when its tracking shows delivery, unless there’s evidence of the loss.

Claims and what each won’t carry

Canada Post gives 90 days after shipping to claim for loss or damage, and pays only the sender. Its Regular Parcel includes no coverage, and it accepts no damage claims for ceramics, glass, porcelain or perishables. UniUni gives sellers on its own platform 15 days, and sends recipients to the seller. A label bought through ProtonShip is claimed through ProtonShip, from the shipment in your account. See claim deadlines for every carrier.

UniUni’s list of what it won’t carry is the stricter of the two. It refuses all alcohol and perishables, cannabis, tobacco and vape cartridges, firearms, knives and tasers, dangerous goods, cash, and very fragile items such as glassware and porcelain. Canada Post takes perishables at the sender’s risk, with no damage coverage. Compare all five carriers on our prohibited items page.

What recipients say

On October 11, 2026, UniUni’s Trustpilot profile scored 1.1 out of 5 from 2,945 reviews, and the Better Business Bureau rated it A. Trustpilot notes that UniUni hasn’t invited reviews recently, so they may not be representative. Our UniUni delivery guide explains each tracking status.

Which costs less?

Neither is cheaper every time. UniUni is built for light parcels going to homes in cities, and Canada Post’s Regular Parcel bills a light, bulky box at the 166 divisor. Neither lists a separate charge for homes. The weight, the size and the distance decide it for each parcel.

Once Canada Post joins ProtonShip quotes, one quote will price both for your parcel, with fuel and the surcharges known at booking already included. Until then, a quote shows UniUni next to Purolator, UPS and FedEx, so you can see for each parcel whether UniUni is the right pick.
