How this is worked out
Subtotal = labour + parts + shop supplies.
A tire fee line = the fee on one new tire of that class × the number of tires. The fee is the one the province's own program sets.
Each tax = its rate × the amount it is calculated on. That amount is labour, parts, shop supplies and the tire fees, each only where the province charges that tax on it, and it is shown in the tax's line.
No tax is calculated on another tax. Where a province has two, each is calculated on the price before either.
Each tax is rounded once, on its whole amount, to the nearest cent, and a half cent goes up. Total = subtotal + the tire fee lines + the taxes, as they are shown.
What this covers
This covers a retail repair invoice to a consumer, in Canadian dollars (CAD), from a shop that is registered to collect each tax.
It does not cover a customer who is exempt from a tax, or a vehicle that is being repaired for resale.
It does not cover fees other than the fee on a new tire, such as those on oil, oil filters, antifreeze and batteries.
It does not cover tire classes other than the ones listed for the province, such as agricultural, off-road and other commercial tires.
Not yet covered
Nothing is worked out for these, because a rule has no source yet:
Northwest Territories: No source says whether a fee on a new tire exists. A tire recycling program was announced as planned in 2021, and no fee schedule was found.
Nunavut: No source says whether a fee on a new tire exists. None was found.
This is arithmetic, not accounting or tax advice.
