Hi nickita,
This is also curious, but I don't know if it is related to Jennie's issue. In your case, the grand total is still OK but hers is not.
Can you describe to me the order that gave these numbers? How many items, what were their values... were they priced by attribute... things like that. The more detail the better. Also, are you running any other mods? Does the tax total come out OK when you turn off the split tax lines mod?
That depends on how you have your tax rates set up, and doesn't have anything to do with this mod. I'm not a tax accountant but I'm under the impression that in Ontario you do have to charge PST on shipping. Here's a good thread (link) on setting up taxes for Canada. Maybe someone there will have a better answer for you...
