How to start a framing business in Ontario

Framing crews build the structure — walls, floors, and roofs — for builders and GCs, usually at piece rates per square foot. No licence is required; speed, crew, and a builder relationship are the business.

The steps to start your framing business

  1. 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.

  2. 2

    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.

  3. 3

    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.

  4. 4

    Handle framing licensing & permits

    No provincial trade licence — carpentry (403A) is voluntary. You need a municipal business licence, WSIB, insurance, and mandatory safety training (Working at Heights for anything off the ground). The work itself is governed by the builder's permits and the Ontario Building Code; framers work under the builder's permit rather than pulling their own.

  5. 5

    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.

  6. 6

    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.

  7. 7

    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.

  8. 8

    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.

Insurance for a framing business

Framing carries serious fall and structural-collapse exposure — among the higher WSIB rate groups. Carry $2M CGL minimum and keep Working at Heights current across the crew.
