What an hour of your crew actually costs you once CPP, EI, WSIB, vacation pay, stat holidays, benefits and EHT are on top of the wage. Statutory-only residential lands near 18%; with tenure, benefits and a G3 rate it reaches 25–26%.
CPP and EI are capped, so the percentages depend on what a worker earns in a year — that is why the wage and hours matter here.
