How to setup Canadian Tax Zones for expense receipts

I am not in any way knowledgable on how to setup tax zones for a Canadian client.  Are there detailed instructions on how to setup tax zones for an Acumatica tenant that does have Canadian Localization turned on?
For example : I want two tax zones setup for British Colombia
CADBC with GST 5% and PST 7% (GST GL# 2510, sub 00009.900)(PST GL# 2510, sub 00100.900)

CADBCSR with only GST 5% (GST to GL# 2510, sub 00009.900)

What are the steps I need to perform to do this?

And then be able to assign those tax zones to Employees, which I know how to do.
(BTW, these will exclusively be used for Expense receipts)
