Outdoor water storage is it possible outside of BC?

[corpusse]

I am not aware of anyone doing this but I've also never considered it. I've just moved into a basementless house and for the first time in my life the tanks will be in the living space of the house not tucked away in the basement. That being said a fishroom is impossible for now and I need somewhere to store water.

Ideally I will have my 2 55 gallon drums one for RO and one for salt water. I am considering everything from a solar powered shed that powers either a spaceheater or the water heaters to using a woodstove, to keeping the water super salty and avoid major winter water changes. Basically I'm throwing this out there for ideas. I am in Northern Ontario so it's going to get COLD.

The backup plan is sticking one barrel in a corner of the house and covering it with wood to look like a table or something but ideally I can find a way to make this work outside.
