Registering a sole proprietorship or partnership in Ontario is generally the fastest and lowest-cost way to start operating legally under a business name. It's a separate process from incorporation — the business and its owner remain the same legal entity — and the registration typically needs to be renewed every five years to stay valid and in good standing.
Ideal forNew business founders, sole proprietors, and partnerships registering or renewing in Ontario.
Certified expertise, proactive planning, and clear communication — on every engagement.
Sole proprietorship, partnership, or trade name registrations each have specific requirements with the Ontario Business Registry that need to be met to avoid delays.
A CRA Business Number, and the tax, payroll, or GST/HST program accounts tied to it, are typically set up as part of the same registration process.
Ontario business name registrations are generally valid for five years and lapse if not renewed, which can create gaps in a business's legal standing.
Straight answers about how this service works and what we need from you.
Generally five years, after which it needs to be renewed to stay valid and in good standing.
Registering a sole proprietorship or partnership lets a business operate under a name, but the owner and business remain the same legal entity. Incorporating creates a separate legal entity with its own liability protection — a meaningfully different structure.
It's not always mandatory for a sole proprietorship, but a preliminary name search is commonly recommended to confirm the name isn't already in use before registering.
Not automatically — a CRA Business Number and the relevant program accounts (income tax, payroll, GST/HST) are typically set up as a related but separate step.
