General Contractor Agreement (Canada)

A General Contractor Agreement in Canada engages a general contractor for construction work and sets the scope, price, and schedule, governed primarily by provincial construction and lien legislation.

Canadian construction law is heavily regulated at the provincial level. Each province has its own construction lien legislation — Ontario's Construction Act (formerly the Construction Lien Act), British Columbia's Builders Lien Act, and Alberta's Prompt Payment and Construction Lien Act — that imposes mandatory holdback requirements, typically 10% of each progress payment. These statutory holdbacks exist to protect subcontractors and material suppliers, and property owners who fail to retain them can face lien claims even after paying the general contractor in full.

Beyond lien legislation, the agreement must address workplace safety insurance. In Ontario, the Workplace Safety and Insurance Act requires all construction employers to carry WSIB coverage. British Columbia mandates WorkSafeBC registration, while Alberta requires WCB coverage. A properly drafted agreement requires the contractor to provide proof of active coverage before work begins, shielding the owner from vicarious liability for workplace injuries.

The General Contractor Agreement (Canada) also establishes whether the contractor relationship is fixed-price, cost-plus, or time-and-materials, each carrying different risk profiles under Canadian contract law. Section 22 of Ontario's Construction Act (S.O. 2017, c. 24) mandates the 10% statutory holdback from each progress payment; Section 31 of BC's Builders Lien Act (S.B.C. 1997, c. 45) imposes a 10% holdback requirement; Section 18 of Alberta's Prompt Payment and Construction Lien Act (S.A. 2018, c. P-26.4) governs holdback in Alberta. Part I.1 of Ontario's Construction Act introduced mandatory prompt payment: Section 6.2 requires owners to pay within 28 days of a proper invoice and Section 6.4 requires contractors to pay subcontractors within 7 days of receiving payment. Part II.1 of Ontario's Construction Act provides statutory adjudication for disputed invoices without stopping construction work. Section 14 of Ontario's Workplace Safety and Insurance Act (S.O. 1997, c. 16) governs WSIB obligations for construction employers; Section 10 of BC's Workers Compensation Act (R.S.B.C. 2019, c. 1) governs WorkSafeBC registration; Section 89 of Alberta's Workers' Compensation Act (R.S.A. 2000, c. W-15) governs WCB requirements. Section 25 of Ontario's Occupational Health and Safety Act (R.S.O. 1990, c. O.1) imposes duties on constructors at project sites, while Section 26 governs owner obligations. Under the National Building Code of Canada (NBC), construction must meet minimum structural, fire, and safety standards enforced by municipal building permit authorities. The Personal Information Protection and Electronic Documents Act (PIPEDA, S.C. 2000, c. 5), enforced by the Office of the Privacy Commissioner of Canada (OPC), governs any personal information collected from workers or subcontractors during the project. Disputes are adjudicated before the Ontario Superior Court of Justice, Alberta Court of King's Bench, and British Columbia Supreme Court.

When hiring a general contractor for a home renovation exceeding $10,000, where multiple trades (electrical, plumbing, framing) will be coordinated under one project manager.

When building a new residential or commercial structure that requires municipal building permits, inspections, and compliance with the National Building Code of Canada.

When a property owner needs to formalize the contractor's obligation to carry WSIB/WCB coverage, provide certificates of insurance, and maintain workplace safety standards under provincial occupational health legislation.

When the project involves subcontractors, and the owner needs contractual assurance that the general contractor will manage statutory holdback obligations under provincial construction lien acts and pay subcontractors on time.

When converting or renovating a commercial space where the lease requires landlord approval and the contractor must comply with specific building standards or restoration obligations.

Skipping a written general contractor agreement exposes the property owner to uncontrolled costs, lien claims from unpaid subcontractors, liability for workplace injuries, and the absence of any enforceable warranty on completed work. Section 22 of Ontario's Construction Act imposes holdback obligations on owners; failure to comply exposes the owner to lien liability even after paying the contractor in full. Section 14 of Ontario's Workplace Safety and Insurance Act (S.O. 1997, c. 16) can hold owners jointly liable for uninsured contractor workers' compensation claims. Section 8 of British Columbia's Builders Lien Act (S.B.C. 1997, c. 45) and Section 18 of Alberta's Prompt Payment and Construction Lien Act (S.A. 2018, c. P-26.4) impose equivalent holdback obligations in those provinces. Section 25 of Ontario's Occupational Health and Safety Act (R.S.O. 1990, c. O.1) requires the constructor to take every precaution reasonable in the circumstances for worker protection. Without a written contract specifying the contractor's constructor status, owners risk being deemed the constructor under Section 1 of the OHSA and assuming full constructor liability. Part I.1 of Ontario's Construction Act introduced prompt payment: Section 6.2 requires owners to pay proper invoices within 28 days; Section 6.4 requires contractors to pay subcontractors within 7 days of receiving payment. Tarion Warranty Corporation in Ontario administers new home warranty obligations under the Ontario New Home Warranties Plan Act (R.S.O. 1990, c. O.31). Disputes are adjudicated before the Ontario Superior Court of Justice, Alberta Court of King's Bench, or British Columbia Supreme Court, or through statutory adjudication under Part II.1 of Ontario's Construction Act for payment disputes.

Scope of Work and Specifications — A detailed description of all work to be performed, materials to be used, and applicable building codes. Vague scope descriptions are the leading cause of construction disputes in Canadian courts.

Payment Schedule and Statutory Holdback — Progress payment milestones tied to completion stages, with the mandatory provincial holdback (10% in Ontario under Construction Act s. 22, 10% in BC under Builders Lien Act s. 4) clearly identified and held until the lien period expires.

Change Order Procedures — A formal process requiring written approval before any changes to scope, timeline, or cost. Without this, contractors may claim additional compensation for work the owner considered included in the original price.

Insurance and WSIB/WCB Requirements — The contractor must maintain thorough general liability insurance (typically $2 million minimum) and provide a valid WSIB/WCB clearance certificate. Owners who fail to verify coverage may be held personally liable.

Project Timeline and Delay Penalties — Start date, milestone dates, and substantial completion date, with liquidated damages for unjustified delays. Force majeure provisions should address weather, supply chain disruptions, and government-ordered shutdowns.

Warranty and Deficiency Provisions — A minimum one-year warranty on workmanship with a clear deficiency correction process. Provincial new home warranty programs (Tarion in Ontario, BC Housing's 2-5-10 warranty) may impose additional obligations.

Dispute Resolution — Specify mediation or arbitration before litigation, which is standard practice in Canadian construction contracts and can save tens of thousands in legal fees.

Termination Clauses — Conditions under which either party may terminate, including contractor default, owner insolvency, or mutual agreement, with procedures for paying for completed work and returning materials. Section 22 of Ontario's Construction Act (S.O. 2017, c. 24) governs statutory holdback obligations; Section 31 of BC's Builders Lien Act (S.B.C. 1997, c. 45) and Section 18 of Alberta's Prompt Payment and Construction Lien Act (S.A. 2018, c. P-26.4) impose equivalent requirements. Section 14 of Ontario's Workplace Safety and Insurance Act (S.O. 1997, c. 16) governs WSIB obligations for construction employers; Section 25 of Ontario's Occupational Health and Safety Act (R.S.O. 1990, c. O.1) sets constructor duties. Section 5 of PIPEDA (S.C. 2000, c. 5), enforced by the Office of the Privacy Commissioner of Canada (OPC), governs any personal information collected during the project. Part II.1 of Ontario's Construction Act provides statutory adjudication for construction payment disputes, with adjudicators appointed by the Authorized Nominating Authority and decisions issued within 30 days.

Governing Law and Dispute Resolution — The agreement should specify the province whose law governs the contract and the dispute resolution mechanism: mediation, followed by arbitration under the applicable provincial Arbitration Act, or litigation before the provincial superior court. For federal government projects, the Federal Courts Act (R.S.C. 1985, c. F-7) may confer jurisdiction on the Federal Court of Canada. Where the project is a public procurement, the Canadian Free Trade Agreement (CFTA) and the Agreement on Government Procurement may impose additional competitive bidding requirements. The Income Tax Act (R.S.C., 1985, c. 1 (5th Supp.)) governs the tax treatment of construction payments, and the Canada Revenue Agency (CRA) may require GST/HST to be charged on construction services under Section 240 of the Excise Tax Act (R.S.C., 1985, c. E-15). Section 12 of the Canada Business Corporations Act (R.S.C. 1985, c. C-44) governs corporate name requirements for incorporated contractors.
