How to Select a Trailer Hitch
Hitch class and door-sticker limits still matter before brake type. The trailer has to be legal and controllable under the tow vehicle you actually own.
Watch on YouTubeTrailer Surge Brakes versus Electric Brakes (Canada)
Surge brakes versus electric brakes is a practical Canada trailer question, not a brochure argument. Surge brakes are hydraulic and self-actuate when the tow vehicle decelerates into the coupler. Electric brakes need a brake controller in the tow vehicle and a working trailer circuit. Many boat trailers still arrive with surge hardware. Utility and travel trailers more often run electric drums or discs. We stock live CURT electric brake-control gear on this store. We do not invent a surge-specific CURT SKU that is not on the shelf.

Watch these CURT videos first
All four videos are from the official CURT YouTube channel (@curtmfg). Use them for hitch class, install habits, wiring basics, and ball-mount height before you dig into brake-type decisions below.

Trailer Hitch Installation Techniques
Install habits include coupler height and latch feel. Surge actuators dislike a coupler that sits wrong or a latch that is half closed.
Watch on YouTubeHow to Connect a Trailer Wiring Harness
Electric brakes need a working brake circuit from vehicle to trailer. Surge trailers still need sound lighting even when the actuator is hydraulic.

Level the trailer so the surge actuator or electric brake geometry works the way the trailer builder intended.
Watch on YouTubeWhat each brake type actually does
Surge brakes use a hydraulic actuator on the trailer tongue. When you slow the tow vehicle, the trailer pushes into the coupler and the actuator applies trailer brakes. No in-cab controller is required for ordinary surge operation. That is why so many boat trailers ship with surge hardware. Backing up can need a lockout or careful technique, and the actuator still needs fluid, seals, and a coupler that sits square.
Electric brakes use magnets or calipers on the trailer that respond to a signal from a brake controller in the tow vehicle. You gain adjustable gain, often manual apply, and better control on hills when the system is set up correctly. You also take on controller install, a brake circuit through the harness, and a breakaway battery path that can apply trailer brakes if the trailer separates.
We are not inventing provincial weight cutoffs on this page. Rules vary by province, trailer type, and registration details. Read your trailer plate, the trailer builder notes, and the local requirements that apply to your tow. If the trailer already has surge, do not assume you need a controller. If the trailer already has electric brakes, do not assume surge parts will bolt on without a real conversion plan.
Surge
Hydraulic self-actuation
Common on boat trailers and some utility decks. The coupler push applies the brakes. No cab controller for normal stops.
- Watch coupler height and latch feel
- Service fluid and actuator seals
- Plan for reverse lockout habits when the trailer uses them
Electric
Controller in the cab
Common on travel trailers and many utility trailers. Needs a controller, a brake wire, and a breakaway battery path.
- Set gain for the load you actually tow
- Test manual apply before the trip
- Confirm breakaway battery charge
Honesty
No invented cutoffs
We do not invent a Canada-wide weight number on this page. Match the brake system already on the trailer, then confirm local rules for your province and trailer registration.
- Read the trailer plate and builder notes
- Open the related brake guides linked above
- Ask before converting brake types
When each type shows up in the driveway
Step 1Look at the trailer
Find the actuator box on a surge tongue, or magnets and a breakaway switch on an electric trailer.
Step 2Match the tow vehicle
Electric needs a controller path. Surge needs a solid coupler setup and honest lighting.
Step 3Check breakaway gear
Electric trailers need a charged breakaway battery. Surge trailers still need chains and a coupler that stays latched.
Step 4Do a first-tow walkaround
Lights, chains, coupler, tire pressure, then a short controlled stop in a safe lot.
Live CURT gear we can point to honestly
For electric brake control we stock live CURT controller and bracket hardware on this storefront. For surge-specific actuators and hydraulic kits we do not invent a CURT SKU that is not live here. If your trailer is surge, service the actuator you have and keep the coupler honest. If your trailer is electric, start with the controller decision and the breakaway path.

No live surge-specific CURT actuator SKU is linked here because we do not stock one on this storefront today. That is honesty, not a soft promise.
