Why this matters for Canada trades
Trade certification is provincial (with the interprovincial Red Seal endorsement), and payroll/accounting software must handle CRA source deductions, GST/HST/PST, and — for Quebec — French-language and Revenu Québec requirements.
Canadian trades vendor selection is shaped by provincial trade certification (often Red Seal), CRA payroll remittances, GST/HST/PST handling, and bilingual (English/French) requirements in some provinces.
