Requirements Overview
The most critical requirement for operating a motor vehicle supplies and new parts merchant wholesaler in Windsor is product safety and recall obligations. This is a legal requirement, and you cannot legally operate without having processes to verify product safety, manage recalls, and communicate safety information to customers. In addition to this non-negotiable foundation, you also need to meet essential compliance steps such as Occupational Health and Safety Act compliance and obtaining a proper business licence, which are equally fundamental to lawful operation.
Beyond safety and licensing, expect mandatory operational requirements that keep your workplace compliant and functional. Ensure strict Occupational Health and Safety Act adherence, and maintain appropriate coverage through WSIB, along with Commercial General Liability Insurance to protect your business and customers. You’ll also need to comply with Employment Standards in Ontario and, where applicable, secure a Vendor Permit for Retail Sales Tax Exemption. These items help you run a safe, fair, and legally compliant operation day to day.
For registration and tax matters, set up your business numbers and registrations with the right agencies. This includes a Business Number (BN) registration with the Canada Revenue Agency, Ontario Business Name Registration (ServiceOntario), and GST/HST registration. You may also need an Import/Export Business Number for cross-border trade, Payroll Deductions Registration for employee withholding, and the Vendor Permit for any applicable sales tax exemptions. Having these in place streamlines accounting and regulatory reporting.
