Requirements Overview
The most critical requirement for operating a dimension stone mining and quarrying business in Windsor is Occupational Health and Safety Act Compliance. This is a legal obligation you cannot sidestep. Meeting OHSA standards means creating a safe workplace, providing proper training, implementing safety plans, safeguarding equipment, and maintaining ongoing reporting and inspections. It is non-negotiable: you cannot legally mine or quarry without proving and maintaining compliance.
Beyond OHSA, your day-to-day operations must align with mandatory safety, permits, and environmental rules. This includes Industrial Safety Standards to protect workers, a Mining Permit and Closure Plan to govern your activities and eventual site restoration, and Environmental Compliance for infrastructure and site impacts. You’ll also need to follow Employment Standards Compliance to ensure fair wages, hours, and working conditions. Keeping these elements in place helps you run a responsible, legally compliant operation.
On the business side, you’ll need the formal registrations that let you legally operate, bill clients, and manage taxes. This means obtaining a Business Licence, registering your Business Number (BN), and completing Ontario Business Name Registration with ServiceOntario. You’ll also need GST/HST Registration, Payroll Deductions Registration, and WSIB Registration and Coverage to handle tax status, payroll deductions, and workers’ compensation.
Next steps: map out the regulatory steps, gather your documents, and set a realistic timeline. Start with OHSA readiness and safety plans, then contact the provincial mining regulator for permit and closure-plan details. At the same time, set up your registration accounts with CRA and ServiceOntario. If you’d like, I can turn this into a practical 90-day checklist to help you track progress and stay on course.
