Triple E and Big Foot are two Canadian RV makers that are designed for Canadian Weather.
You did not say where in Canada you are or where it is that you will be parking the rig. Do you have access to electricity?
We have a 1989 Triple E Class C and it has enclosed tanks, all the water lines are above the floor as well as storm (double) windows. We rarely get sustained below freezing temps on Southern Vancouver Island and a small ceramic heater is enough to keep the water lines from freezing. We do leave the cupboard doors open.
