How to start an environmental consulting firm in Ontario
Environmental consultants assess and clean up the relationship between projects and the land — Phase I/II Environmental Site Assessments, contaminated-site work, Records of Site Condition, and designated-substance surveys. It is a distinct business from the remediation trade: consultants assess and sign off; contractors do the cleanup.

The steps to start your practice
- 1
Stand up your environmental consulting firm
If the firm offers engineering, it needs a PEO Certificate of Authorization; geoscience work runs under P.Geo qualification. Carry professional liability (E&O) and pollution liability, incorporate, and build relationships with property owners, lenders, and developers who need ESAs before they transact or build.

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.
