tax based on delivery address instead of billing

[skywriter]

I've set my Ontario Canada PST (RST) tax zones, classes, rates properly. 8% is added to the product and shipping costs to Ontario delivery addresses... GOOD!
No tax is added when shipping outside Ontario...GOOD!
If I have a billing address in Ontario, but a delivery address outside Ontario, 8% is added to the product price... NOT good.
If I have a billing address outside Ontario, but a delivery address in Ontario, 8% is added to the shipping costs only...NOT good.

So it seems to me that the Canada Post Shipping module is calling for the proper info. Great.

But what file calculates the product taxes? It seems that it is calculating on the billing, and not the delivery address.

Any help would be greatly appreciated.

Yes the way it is worded is very MISS LEADING! The "Billing Address" is the "SHIP TO" address. Where the PRIMARY ADDRESS maybe what you are thinking as your BILLING address and the selectable "Address list" is really the SHIPPING address. There is no separate "shipping" address listed/used.
