Requirements Overview
The most critical requirement for operating a private household business in Mississauga is Occupational Health and Safety Act Compliance. This is a legal obligation you cannot override, and you cannot legally operate without meeting these safety and workplace rules. It sets the minimum standards to keep you and any household staff safe on the job, and non-negotiable.
In terms of day-to-day operations, you’ll want to align health, safety, and permits. This means following the Occupational Health and Safety Act, establishing safe working conditions, and providing any necessary training or safety measures. If you hire staff, you’ll also handle private household employer obligations and Employment Standards Compliance (covering things like minimum pay, hours, overtime, and leaves). If you hire workers, you should arrange for WSIB coverage to protect both you and your employees.
For the business side, you’ll need the right registrations and numbers. This includes obtaining a Business Number (BN) from the Canada Revenue Agency, securing any required local business license, and registering the Ontario Business Name (ServiceOntario) if you operate under a name other than your own. You’ll also determine GST/HST registration based on your revenue, and set up payroll deductions for your employees (CPP/EI and income tax) through the appropriate CRA accounts. These registrations help you stay compliant with tax, licensing, and payroll rules.
You’ve got this! Start with the safety basics and then tackle registration steps in small, doable bites. If you’d like, I can map out a practical 2-week action plan with concrete checklist items and timelines tailored to your situation in Mississauga.
