FWIW, Canadian taxes are similarly quite uniform within a province.

Canadians also have a Federal GST, and provinces add their own tax, which gets added together into one Harmonized Services Tax (HST) in all provinces but Quebec and British Columbia, which have their own rules (QC collects an additional Provincial Sales Tax (PST))

Of course, there are fun additional taxes as well like the Environmental Handling Fee (EHF) on electronics.
