Absolutely no need to winterize. I’ve lived here 20+ years and have not seen low 20s. Mid to high 20s yes but never multiple days hard freeze. Drain all tanks well and you are good to go. Note that as an ex-Canadian I can tell you that freezing damage to pipes/tanks usually occurs when pipes or tanks are full or under pressure. The issue with water is that it is one of the few materials that expands when it goes from liquid to solid. This is a good thing since it results in ice that floats as opposed to sinking to the bottom of a lake or river. If it sank all of our waterways would be permanently frozen solid. Getting back to freezing damage, if your pipes/tanks have little amounts of water left in them and enough space for the expanding ice to go to you will not experience damage just like freezing water in an open glass does not damage the glass. A bottle of beer under pressure is another story.
