Propane bottle replacement
Raystream- Please check out propane bottle replacement under forums, squarestream. I think your bottles may be the same aluminum worthingtons, but your made date may be too late and canada laws may be different but some squarestream owners have found there is an exemption for their laydown 40 pounders if they are inspected and placarded. There is also reference for U.S. governing bodies for these and they may be able to steer you to like canadian governing rules. I can't see they would ever go bad unless in a high salt air environment or damaged by a physical blow. Cheers.
