A sole proprietorship is subject concurrently to federal law and to the law of each province or territory in which it carries on business. This page identifies, for a sole proprietorship, which requirements are federal, which are provincial or territorial, and how they differ across the thirteen jurisdictions.
FEDERAL REQUIREMENTS
Income Tax Act: computation of business income on Form T2125 and federal tax on the proprietor's T1 return; personal instalments; record-keeping (section 230).
Canada Pension Plan: contributions on self-employment earnings at 11.9% (base and first additional) and 8% (CPP2), except in Quebec, where the Quebec Pension Plan applies.
Employment Insurance: employer and employee premiums where employees are engaged; optional EI special benefits for the proprietor.
Excise Tax Act: GST/HST registration, collection, and remittance once the $30,000 small supplier threshold is exceeded.
Federal programmes administered by the CRA: business number, payroll deductions, and import-export accounts.
Federally regulated activities: the Canada Labour Code applies instead of provincial employment standards where the business is a federal undertaking (such as interprovincial trucking); federal licensing applies in sectors such as broadcasting and aviation.
Other federal statutes of general application: the Competition Act, the Personal Information Protection and Electronic Documents Act (outside Quebec, Alberta, and British Columbia), Canada's anti-spam legislation, and the Trademarks Act for protection of the business name as a mark.

The business name must be registered in each province or territory in which the business is carried on under that name.
GST/HST is charged at the rate of the province of supply, and provincial sales tax registration may be required in provinces in which taxable goods or services are sold.
Employees are governed by the employment standards and workers' compensation regime of the province in which they work.
