The steps to start your environmental remediation business
- 1
Incorporate your company
Most contractors incorporate (Ontario or federal) to limit personal liability, look credible to larger clients, and access tax advantages once profitable. You choose a named or numbered company, set directors and share structure, and file the articles. Budget roughly $400–$600.

Register your CRA accounts
Get a Business Number, then register for HST/GST (mandatory once you exceed $30,000 in revenue, and worth registering sooner to claim input tax credits), a payroll account if you will hire, and corporate income tax. This is free and done through the CRA.

Register for WSIB
Construction is a mandatory WSIB sector. Independent operators and partners in construction generally must register even with no employees, and clients and general contractors will require a valid WSIB clearance certificate before letting you on site.

Handle environmental remediation licensing & permits
No single trade licence, but remediation is heavily regulated: the Ministry of the Environment, Conservation and Parks (MECP) governs contaminated-site cleanup and Records of Site Condition; asbestos/lead/mould abatement follows O. Reg. 278/05 and 490/09; and Hazardous Materials Worker (253H) certification applies. Qualified Persons (often engineers) sign off remediation.

Get insured
Carry Commercial General Liability (typically $2M, $5M for commercial/industrial work), plus tools and equipment, commercial auto, and — depending on scope — builders risk and professional liability. Many contracts and clients specify minimum coverage before you can quote.

Set up health, safety & compliance
Meet your Occupational Health and Safety Act duties: a health and safety policy, required training (WHMIS, Working at Heights where applicable), and — for commercial and public work — often COR® certification. This is also where any trade-specific safety tickets live.

Stand up your operations
Open business banking, set up construction-specific accounting, and understand your trust obligations under the Construction Act (holdback, prompt payment, and adjudication). This is the back office that keeps you paid and out of trouble.

Get bid-ready and win work
Assemble your prequalification package — incorporation and WSIB documents, insurance and bonding letters, safety program, key personnel, and project references — then quote, send proposals, and collect on invoices. This is where a construction business actually makes money.
