Thanks for the replies. Rec'd the following from a contact. Looks like I'm in good shape. Hope other folks headed north to leave some $$ will have the right gear on their trailers....
British Columbia
(Please note: Due to past confusion regarding BC's braking laws, this section includes more details than just the requirements for tow bars/trailer brakes.)
Trailer Brake Requirements
• Gross trailer weight of 1,400 kg (3,080 lbs) or less - Brakes are required if the trailer and its load weigh is more than 50% of the licensed weight of the vehicle towing it.
• Gross trailer weight of 1,401 kg (3,081 lbs) to 2,800 kg (6,160 lbs) - Brakes are required, including a breakaway brake.
• Gross trailer weight of more than 2,800 kg (6,160 lbs) - Brakes are required, and the trailer brakes must be capable of being applied by the driver independently of the towing vehicle's brakes. A surge brake does NOT meet this requirement. A breakaway brake is also required. Brakes are required on all axles. The sole exemption to this rule is for a 3 axle house trailer, in which case brakes are only required on 2 of the 3 axles.
Towing Dolly Brake Requirements
• Gross weight of dolly and motor vehicle carried is 1,400 kg (3,081 lbs) or less.
• Brakes are not required on the dolly if the net weight of the dolly plus (+) the gross weight of motor vehicle carried plus (+) the gross weight of tow vehicle equals (=) less than the gross vehicle weight rating of the towing vehicle.
• Combinations other than the two outlined above require brakes on the towing dolly. Brakes are not required on the motor vehicle being carried by the dolly.
Tow Bar Brake Requirements
• Motorhome and Towed Motor Vehicle - If the towed motor vehicle has a gross vehicle weight of less than 2,000 kg (4,400 lbs) and is less than 40% of the gross vehicle weight rating of the motorhome, brakes and co-ordinated brake control are not required.
• Commercial Vehicle with GVWR over 5,500 kg (12,100 lbs) and Towed Motor Vehicle - If the aggregate weight of the combination does not exceed the GVWR of the commercial vehicle brakes are not required on the motor vehicle being towed.
• Other Combinations - If the combination is not included in the two situations outlined above, brakes are required on all wheels of the motor vehicle being towed in the same manner as trailer brake requirements.
• General Brake Requirements.
• Brakes with which a trailer is equipped when applied must be adequate to maintain control of the trailer; when applied must not affect the direction of travel of the trailer.
• Breakaway Brake Must automatically apply when the trailer separates from the tow vehicle and when applied must be capable of remaining fully applied for at least 15 minutes.
Detached Trailers
No person shall park or leave a detached trailer at any place on a highway unless the wheels are locked so that the trailer will remain stationary at that place.
A message from BC regarding Brake Controllers
Never use a brake controller that taps into the hydraulic brake system of a tow vehicle equipped with ABS brakes unless the manufacturer specifically intends the controller for this situation.
If your tow vehicle has ABS brakes, Transport Canada recommends that you use an inertial* brake controller to operate the trailer brakes rather than a controller that operates the trailer brakes when it senses the tow vehicle brake lights turn on. This will prevent possible electronic interference with the ABS controller.
*An inertial controller has a small weight inside that moves in response to the tow vehicle decelerating and sends electrical power to the trailer brakes in proportion to how much the tow vehicle decelerates. An inertial brake controller does NOT tap into the existing hydraulic brake system of the towed vehicle (trailer); hence it does not interfere with the electronic components of the existing ABS brake system of the towed vehicle.
