How do I avoid toilet freezing in the winter of Canada?

Mike:

I’ve lived in Canada for my most of my life. (Since I was 4)

I can say without a doubt that I have never, not even once, had to do anything to prevent a toilet from freezing nor have I ever had a toilet freeze nor have I ever heard of anyone having a toilet freeze. 

It isn’t “a thing” here in Canada for the simple reason that we have building codes and houses are not designed and built by morons who don’t understand the concepts of insulation and heating.

Yes, our igloos are made of snow and ice, but I can assure you that our plumbing and electricity are right up-to-date!
