Which Freight Needs Freeze Protection
Plenty of products are damaged by freezing even though they are not perishable in the usual sense. Water-based liquids, paints and coatings, adhesives, cleaning products, beverages, canned goods, and some chemicals can separate, burst their containers, or lose their properties after being frozen once. Electronics and certain batteries can also be affected by extreme cold.
If you are not sure whether your product can handle a Canadian winter, check the manufacturer's storage temperature range. If the minimum is above the lowest temperature your freight might see in transit, you should plan for freeze protection.
Heated Service Versus Reefer
A reefer trailer is a refrigerated unit, but most modern reefers can also heat. That makes a reefer set to a protect-from-freezing temperature a common way to keep winter freight above the danger zone. It is a different job from keeping product frozen or chilled, and it is usually set to a moderate temperature rather than a cold one.
Not every dry van can be heated. Some carriers use insulated trailers or heating equipment, while others will not take freeze-sensitive freight at all. We confirm exactly what equipment is being used before booking so there are no surprises on the dock.
Planning Transit Around Winter Weather
Winter adds real variability to transit times. Snow squalls, lake-effect storms, and highway closures can delay a truck by hours or days, particularly on routes through Northern Ontario, the Prairies, and the mountain passes in BC. A delayed truck is also a truck sitting longer in the cold.
For freeze-sensitive freight, we favour direct routing, avoid unnecessary stops, and build extra buffer into delivery windows during winter months instead of promising a best-case timeline.
LTL and Freeze Protection
LTL freight spends time on terminal docks, in cross-dock buildings, and on multiple trucks, and each of those handoffs is a chance for exposure to cold. Standard LTL service does not guarantee heated handling, and many LTL carriers offer protective service only on certain lanes and for an additional charge.
If your product is freeze-sensitive and you are shipping a small quantity, ask us about protective LTL options or whether a dedicated truck makes more sense once you factor in the cost of a ruined shipment.
Packaging and Loading Tips
Good packaging helps but does not replace a heated trailer. Insulated wraps, thermal blankets, and keeping product off the trailer floor and away from the walls can slow heat loss. Pre-warming the product and the trailer before loading, and minimizing the time the doors stay open during loading, matter just as much.
Make sure your paperwork clearly states the freeze-protection requirement and the minimum temperature. Drivers and dock staff cannot protect what they do not know about.
What It Costs and What It Saves
Heated or protect-from-freezing service costs more than standard dry van because of the equipment and the fuel to run it. That cost is small compared with the value of a frozen load, the replacement shipping, and the delay to your customer.
We quote protected service clearly upfront so you can compare it against the real risk to your freight, rather than finding out the hard way in January.
Winter Weather Delays: What Shippers Should Expect
In Ontario, lake-effect snow squalls can close stretches of highway quickly, especially in the snowbelt regions east of the Great Lakes. Northern routes, including those toward Sudbury and Thunder Bay, can see difficult conditions and long stretches without services. In the west, mountain passes and open Prairie highways can close during storms, and delays often cascade from one day to the next.
Plan for a day or two of additional buffer on long winter hauls, and tell your receivers to expect variability. A realistic timeline communicated early is far better than a best-case promise that falls apart when the first storm arrives.
A Cold-Weather Shipping Checklist
Before booking, confirm your product's minimum safe temperature and whether it needs heated service. Ask the carrier what equipment is being used and whether it will be running during the entire trip, including stops. Make sure the freight is not left sitting on a cold dock before loading, and have the doors closed as quickly as possible once the truck is loaded.
Put the freeze-protection requirement on the bill of lading, give the driver a contact for questions, and check that the receiver is open and staffed when the truck is due. A frozen load that sits outside a closed warehouse overnight can be lost even if the trip itself went perfectly.
Frequently asked questions
What temperature should freeze-protected freight be kept at?
It depends on the product. Many shippers use a protect-from-freezing setting well above zero. Check your product's minimum storage temperature and tell us so we can set the right target.
Can any carrier provide heated trucks?
No. Only some carriers have heated or insulated equipment, and availability varies by lane and week. We confirm the equipment before booking.
Is a reefer the same as heated service?
A reefer unit can heat as well as cool, so it is commonly used for freeze protection. The set point is different from a frozen or chilled load.
Is LTL safe for freeze-sensitive products?
Standard LTL does not guarantee heated handling. Protective LTL service exists on some lanes at extra cost, or a dedicated truck may be the safer choice.
When should I start planning for winter freight?
Before the first hard freeze. Confirm your product's temperature limits and your carrier's equipment in October or early November rather than after the first cold snap.
