Canada has multiple levels of taxation, there's a federal goods and services tax (GST) and provincial sales tax (PST). These would be equivalent to the VAT.
Where I live there's no provincial tax on natural gas but some provinces charge PST and others charge the "carbon tax" on top of that. And oh yes the federal government charges the GST on natural gas regardless of where you live.
With exceptions like fuel, the federal government can't tax natural resources as it's under provincial jurisdiction but they are trying hard to impose a "carbon tax" on provinces to virtue signal and ensure a steady flow of revenue for their vanity projects under the disguise of "environmental concern".
Liberal policies are reverse Robin Hood schemes. It's a shame so many people believe in their crap, but I guess it takes a while for people to realize they are being fooled.
