Here's the Canadian version of the Hydrofarm, a good and affordable option. Most pet stores don't carry them, but you can usually find them easily online. If you go to a local pet store, try looking for the R-Zilla dial thermostat (like this). It's not as frequently recommended, but it'll do in a pinch.

PVC enclosures are those like Animal Plastics or Boaphile. I bet someone here could recommend a Canadian option. They're made from plastic and hold heat and humidity much better than a tank. They are also front-opening, so you don't have to deal with moving lids or lamps to access your snake. They're a good long-term option to consider if/when you find maintaining proper husbandry is a hassle with a tank.

You may also consider keeping your snake in a clear Sterilite/Rubbermaid/RUB plastic bin. As above, because it's plastic it hold heat and humidity better than glass. It's also much cheaper. However, it's not as easy to view your snake so it's not the best option for everyone.
