Hi i would like to know how many layers and which clothes are necessary to keep warm in winter? likes Toronto winter.

Im frome a very warm place (Cancun) and im going to travel maybe to live in Toronto.

I have spinal cord injury level C6, so i can't feel when my legs and feet are cold.

i have to know if i need to increase the width of my seat for the clothes. my actual chair is 16.5" of seat width and i have .5" of free space.

Thanks
