Each province has its characteristics. I work in Ontario as an accountant. Do you have an explanation and instructions for the provinces’ differences in bookkeeping their accounts for small businesses? Especially sales tax?
Explanation is that each province has the right to establish their own provincial sales tax, and the rules for it. Some have opted for a system that is harmonized (combined) with the federal GST (see link below). You can find the different provincial rates and rules posted online - probably in multiple places, but most obviously on each province’s government website. A basic Canadian tax class would probably be helpful for you - see links below.
