Help for getting gas in Canada

[Road_To_Nowhere]

Hello everybody,

as the title says, I'm currently living in Canada. I'd like to ctb with the exit bag method, but I have no idea about how I could get the gas (nitrogen or argon, doesn't really matter). Can anyone help me?
Thank you

It depends on where you live.

Some Tractor Supply Stores rent out large cylinders for metal work/sauntering. Deposit ~$500 plus cost of gas.

But you'll require a safe transportation method (upright), preferably in the bed of a truck.
They will want to hear a story what you need it for if you are not a regular.
You can't lay the cylinder flat in your trunk (risky if you get into an accident). You'll need a cart/trolley to transport it and it's a bit conspicuous to carry into an apartment building.

Lots of things to think about.
