I frequent several haulers/truckers forums and many Canada LTL owners/operators use LT tires on their GN trailers and go through scale houses in every province and have no issues. RV should be no different.
Canada follows fed FMVSS safety standards on tire selection so just like the states the myth like not being able to use LT tires on a trailer comes under the heading of misinformed myth from individuals and a few rooky tire dealers.
THE SAFETY ACT โ CANADA
Transport Canada has established Canada Motor Vehicle
Safety Regulations (CMVSR) for various categories of
motor vehicles and motor vehicle equipment under the
provisions of the Motor Vehicle Safety Act, R.S.C. 1993.
The Canadian standards generally coincide with those of
the United States, except for speedometer callouts, cluster
indicators, daytime running lamps (optional U.S.A.),
reflecting surfaces, steering control system, impact
protection, occupant crash protection, occupant restraint
systems, interior/exterior noise and radio interference
(CRFI) requirements.
