How we price this for Toronto
We take each Canadian national base range and multiply it by a local index of 0.99, built from provincial wage data (there is no Canadian equivalent of the U.S. Regional Price Parity, so the price and overhead terms are held at the national baseline):
local range = Canadian national base × 0.99
The wage term uses Canadian national wages for appliance servicers (Job Bank NOC 72402). Parts ship at national prices, so only the labour share moves with the province. All figures are in Canadian dollars — we never convert U.S. prices; the Canadian base ranges come from Canadian sources. These localized estimates are cross-checked against 2 locally published service fees in the observed stat above — CAD figures we show verbatim, never run through the index. The full method and vintages are on the methodology page.
