I've (temporarily) misplaced the file on toad braking laws in the U.S., but we have one for Canada in our library. Click the Library button above, select RV'ing in Canada and click Canada brake laws by province.
Although I have the M&G air brake system, I also tell people that the Brake Buddy is a good option for folks who either don't have air on their coach or don't want to bother with the installation required for an M&G system. M&G requires tapping into an air junction box on the coach and installing, at minimum, an air cylinder between the toad's master cylinder and boost. The Brake Buddy merely requires placing the box on the floor of the toad, hooking up a lever to the brake pedal and plugging into a cigarette lighter. If you buy another toad you just move the BrakeBuddy to the new one, but M&G would require installing an air cylinder on the new vehicle; M&G does offer a trade-in allowance on the old air cylinder.
Pros and cons (simple version): There's no permanent installation required with the Brake Buddy, but there's no box to put in and out (and store) every time with the M&G system.
The only other system I've used and can therefore comment on is the Roadmaster BrakePro sold by Camping World. That system, which is also a box that you put on the floor of the toad but operates on a different principle from BrakeBuddy, was just a disaster and I couldn't recommend it to anyone. Had it worked the way my borrowed neighbor's BrakeBuddy worked, I probably would have been a happy camper and would not have needed to buy the M&G.
There are other alternatives, including the Blue Ox Apollo (another box on the floor) which gets good reviews, and M&G's option for folks who have hydraulic brakes on their coach, but I haven't used any of these alternatives and so can't comment.
