Hmm I set it up with two new taxes and set them to Taxed line items: shipping I've also set up workflow to charge PST and GST on shipping to orders in my province but the taxes seem way out of whack

This is what it looks like. This item only has one tax since its considered food.

Subtotal: $12.00
Canada Post Regular: $5.93
Subtotal excluding taxes: $17.93
PST on Shipping: $1.26
PST: $0.04
GST: $0.60
GST on Shipping: $0.90
Order total: $20.73

What should be the weight of each tax?
