Licence class by trailer weight, by province
CanadaEvery province lets you tow on the ordinary licence up to a line. Here is each line, what it weighs, and what you need above it.
What can I tow on my licence?
On the ordinary car licence, Class 5 in most provinces and Class G in Ontario, you can tow a trailer up to the province's weight line. Of the 7 provinces we have read, 5 draw that line between 4,500 kg (9,921 lb) and 4,600 kg (10,141 lb). Alberta and Quebec draw no trailer weight line at all. The other 6 are marked "Not yet verified".
What differs most is what gets weighed: the loaded trailer, the weight it is registered for, or every towed vehicle added together. That changes the answer for a trailer near the line. To run your own rig, use the licence checker on CDL thresholds and towing licences, which applies the same rows.
Law, not advice. The licence decides who may drive the rig, not how much it can tow. Your vehicle's GVWR, GCWR and hitch rating still apply; Can I tow this? checks those.
Trailer licence by province and territory
The line is given in kilograms, the unit the law uses, with pounds after it.
| Province or territory | Ordinary licence | You need more when the trailer is | Then you need | Law |
|---|---|---|---|---|
| Alberta | Class 5 | No trailer weight line No weight line: a two-axle vehicle may tow any trailer without air brakes | Class 1 if the trailer has air brakes Alberta draws no trailer weight line for the licence. Class 5 also covers a recreational vehicle with up to 3 axles. A tow vehicle with 3 or more axles needs Class 3. | Operator Licensing and Vehicle Control Regulation (Alta. Reg. 320/2002), ss. 21 to 25 and 27 |
| British Columbia | Class 5 | over 4,600 kg (10,141 lb) the towed vehicles in the combination (ICBC: the loaded trailer) | House trailer endorsement (Code 07), heavy trailer endorsement (Code 20), or Class 3; Class 1 with air brakes BC measures the loaded trailer, so weigh it full of water, propane and gear. A tow vehicle with 3 or more axles needs Class 3. | Motor Vehicle Act Regulations (B.C. Reg. 26/58), s. 30.01(2) ; ICBC, Are you planning to tow a trailer weighing more than 4,600 kg? (PI270) |

| New Brunswick | Class 5 | over 4,500 kg (9,921 lb) the towed vehicle's registered gross vehicle mass | Class 3; Class 1 if the trailer has air brakes New Brunswick uses the weight the trailer is registered for. | General Regulation (New Brunswick), N.B. Reg. 83-42, s. 22(1) |

Trailer licence in Ontario
On a Class G you can tow a trailer up to the line: you need more when the trailer is over 4,600 kg (10,141 lb), measured on the total gross weight of the towed vehicles. Above it: Class A (a restricted Class A covers trailers without air brakes). Ontario also caps a Class G combination at 11,000 kg total; over that, with a towed weight within 4,600 kg, it is Class D. The regulation measures gross weight (and registered gross weight for the vehicle), so entering the GVWR is the cautious reading. Source: O. Reg. 340/94 (Drivers' Licences), s. 2, under the Highway Traffic Act (Ontario); O. Reg. 340/94 (Drivers' Licences), s. 4; Ontario Ministry of Transportation, Get a truck driver's licence.
The restricted Class A (condition R) is for smaller truck and trailer combinations, such as a recreational, horse or utility trailer, without air brakes. It does not cover a tractor-trailer or doubles (Ontario Ministry of Transportation, Get a truck driver's licence). There is also an exception for fifth-wheel campers in O. Reg. 340/94 (Drivers' Licences), s. 4; the details and the arithmetic are on the CDL thresholds page.
Trailer licence in BC
On a Class 5 you can tow a trailer up to the line: you need more when the trailer is over 4,600 kg (10,141 lb), measured on the towed vehicles in the combination (ICBC: the loaded trailer). Above it: House trailer endorsement (Code 07), heavy trailer endorsement (Code 20), or Class 3; Class 1 with air brakes. BC measures the loaded trailer, so weigh it full of water, propane and gear. A tow vehicle with 3 or more axles needs Class 3. Source: Motor Vehicle Act Regulations (B.C. Reg. 26/58), s. 30.01(2); ICBC, Are you planning to tow a trailer weighing more than 4,600 kg? (PI270).
And in the United States?
The US has a federal commercial licence test (the CDL) and each state's own classes beneath it. The federal lines, the states we have read so far (California, Florida, New York, Texas) and a checker for your own rig are on CDL thresholds and towing licences.
