To serve our customers across Canada, whether you're in a major city or completely off the grid, many of our products are shipped via freight delivery to ensure safe and efficient transport. Depending on your location and the item, you’ll have the option to pick up from a nearby warehouse terminal or request home delivery.
Free Terminal Pickup on Most Large Items
Most large items we sell, including appliances, solar kits, and other freight-shipped products, include free shipping to your closest warehouse terminal.
Your order will be delivered to the nearest terminal based on your location, where you can pick it up at your convenience.
Need it delivered to your home or cabin? We can set that up for you. There is a small additional fee for residential delivery.
Remote and Hard-to-Reach Locations
If you live in a remote area or outside standard freight zones, please contact us before placing your order.
Some rural locations may require additional charges or special delivery arrangements. We'll confirm everything with our freight partner before shipping.
Local Pickup Options Across Canada
We work with warehouse terminals in every province, so many of our products can be picked up locally to save on shipping costs.
Not all items are eligible, so if you're unsure at checkout, give us a call or send us an email and we'll confirm the best option for your area.
Shipping Times and Order Processing
Orders are typically processed within 1 to 3 business days from the time of purchase, excluding holidays and weekends.
Shipping times will vary depending on the product and your location. On average:
- Ontario and Quebec: 2 to 5 business days
- Western Canada: 4 to 7 business days

We will provide tracking details when available once your order has shipped.
Receiving Freight Shipments
For large freight deliveries, you will receive a call from the carrier or your nearest terminal when your order is ready for pickup or delivery.
Important: Always inspect your shipment before signing any paperwork.
If the box or pallet is damaged:
- Do not sign the Bill of Lading (BOL) as "received in good condition"
- Instead, note the damage clearly on the BOL
- Or refuse the shipment if damage is significant
If no damage is recorded and the shipment is accepted, the freight carrier will consider it delivered in perfect condition. In that case, we cannot issue a refund or replacement. This is a strict freight carrier policy and applies to all deliveries.
Damaged or Missing Items
If there’s an issue with your shipment (whether it’s damage, missing parts, or anything unusual) please contact us within 48 hours of receiving the item. Be sure to include photos whenever possible, as these are often required to file a freight claim on your behalf. If the item was shipped to a terminal, it must be picked up within 48 hours or a $45/day storage fee will apply.
We have a 30-day return policy, which means you have 30 days after receiving your item to request a return.
To be eligible for a return, your item must be in the same condition that you received it, unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase. Shipping costs back to Canadian Off Grid are the responsibility of the customer and 15% restocking fee will apply.
To start a return, you can contact us atryan@canadianoffgriddepot.com. If your return is accepted, we’ll contact you to discuss options, as well as instructions on how and where to return your item. Items sent back to us without first requesting a return will not be accepted.
