Requirements Overview
The most critical requirement for operating a business in Windsor is Occupational Health and Safety Act Compliance. This is a legal obligation you cannot operate without—your safety program, training, hazard controls, and incident reporting must meet Ontario’s OHSA standards. There is no room for shortcuts, and non-compliance can lead to fines, orders to halt operations, or worse. Start with building a solid, documented safety plan that matches local rules and keeps your workers protected.
Mandatory Operational Requirements: In addition to OHSA, you’ll need the practical pieces that keep daily operations lawful and safe. Obtain a valid Windsor business licence to legally operate, and ensure you have WSIB registration and coverage for your workers. You must also comply with Ontario Employment Standards (things like minimum pay, hours, overtime, and leaves). If your international affairs work involves government activity, you may also encounter Security Clearance and Screening requirements and Government Program Administration Standards. These items collectively ensure your business runs smoothly, safely, and in line with official expectations.
Business Registration & Tax: The formal registrations and numbers you’ll need include the Canada Revenue Agency Business Number (BN) for payroll, taxes, and invoicing. You’ll likely register your Ontario business name with ServiceOntario if you’re trading under a specific name. For tax purposes, obtain GST/HST registration, and set up Payroll Deductions registration if you have employees. Keeping these registrations current helps you stay compliant and prepared for audits or reporting deadlines.
Encouragement: Take it step by step and keep momentum. Start with the OHSA compliance plan, then secure the necessary licences and worker coverage, followed by the essential registrations and tax numbers. Windsor’s small business resources and government websites can guide you through each step. If you’d like, I can outline a simple
