How to start a transportation engineering firm in Ontario
Transportation engineers design and study how people and vehicles move — road design, traffic signals, and the Traffic Impact Studies that almost every development needs. Municipalities, MTO, and developers are the clients.

You must be licensed first. A practice can only offer transportation engineer services to the public once it holds the regulator’s firm authorization, which requires a licensed principal and professional liability insurance. Sort the firm authorization before you take work.
The steps to start your practice
- 1
Get a PEO Certificate of Authorization
A Certificate of Authorization lets your firm offer transportation engineering to the public, with professional liability insurance in place — the gate to taking traffic and road work as a business.

Incorporate (or form a professional corporation)
Most professionals incorporate to limit liability and for tax efficiency. Several regulated professions (architects, engineers) can form a professional corporation with a Certificate of Authorization — confirm the right entity type with your regulator before filing.

Set up your CRA accounts
Register for a Business Number, HST/GST (mandatory above $30,000 in revenue), payroll if you will hire, and corporate income tax. Professional service fees are HST-taxable.

Carry professional liability (E&O) insurance
Errors & omissions insurance is the core coverage for a professional practice — and a firm-authorization condition for regulated professions. It protects against claims arising from your professional advice, designs, or certifications.

Stand up your practice operations
Business banking, professional accounting, engagement letters and contracts, and the project and document workflows a practice runs on. This is the back office that keeps you paid and protected.
