Your right Bob, most province in Canada required a Brake system on Dolly with total weight over 3,000 pd. How ever no one will stop you to check your total weight. The only time you would get pull over for a Dolly is if there a safety issue that a policemen would notice, like light not working, no safety chains or safety chains dragging on the pavement, stuff like that. Plus here in Canada we need to register and plate our Dolly like a regular Trailer. But then again if your from the US and don't have plate on your Dolly, don't worry about it, your still OK due to the fact it a US Dolly.
