Is this once, or many times, or far? What kind of road? Mountains? You can bolt on a bumper hitch onto the Accord and flat tow for a couple miles, and likely much farther if the Accord is idling in N. IIRC, in Ontario you can flat tow almost anything with anything, but that's irrelevant to you.
Probably easiest is go to a trailer place that installs hitches and get the legal run down on what your location requires for what you want to do. The actual person with the expertise, not the sales guys. Typically anything that you can get a class 3 hitch for with a 2" reciever will tow a car on a dolly, so almost every midsize SUV, minivan has that available, I put one on my Outback, and even my 2003 4 cyl tracker.
The legal vehicle requirements in Ontario for a private citizen aren't even really mentioned in the highway traffic act, so if you install a 3500lb rated hitch system on your Smart Car, you can tow a 2990lb gross weight unbraked single axle trailer, legally, as long as you don't exceed the rear axle rating of the car, but you could get a weight distribution hitch and load up both axles. Not a great idea, but totally legal to do.
Uhaul lists in Ontario, that only a 2000lb 2" ball is required for their tow dolly rental, and the tow vehicle needs to weigh more than the towed vehicle, so maybe tow dollys require much less hitch rating?
I have a 3500lb rated tow system on my 2.5 Outback and recently towed ~3000lbs for several short trips on back roads hauling round bales, and it was 100% fine. If it was legal to use a tow dolly with your Accord on it, I would have no worries towing it at 55-60 mph anywhere but the mountains, and then its only the drivetrain I'm worried about.
