General Contractor Agreement Cost Plus Fee Template for Canada

A General Contractor Agreement Cost Plus Fee is a construction contract where you pay your contractor for the actual costs of labor, materials, and equipment, plus an additional fee for their services. This agreement type offers transparency in project costs while providing flexibility to accommodate changes during construction, making it ideal for complex projects where traditional fixed-price contracts may not be suitable.

When do you need this document?

You need this agreement when undertaking construction projects where the final scope cannot be precisely determined upfront. It's particularly valuable for renovation projects where hidden structural issues may emerge, custom home builds with high-end finishes, or commercial projects requiring specialized materials. This contract type works well when you want full visibility into project costs and prefer to pay for actual expenses rather than estimated amounts. You should also consider this agreement for projects involving new technologies or construction methods where cost estimation is challenging, or when working with trusted contractors on long-term projects where partnership and transparency are prioritized over fixed pricing.

Key legal considerations

The most critical aspect of this agreement is clearly defining what constitutes reimbursable costs versus contractor fees. You must establish detailed procedures for cost documentation, approval processes for expenses, and regular reporting requirements. The contract should specify markup limitations on subcontractor costs and materials, define overhead allocation methods, and establish maximum project cost limits to prevent budget overruns. Payment terms must align with provincial lien legislation, including proper holdback procedures and payment timelines. Risk allocation clauses should address cost overruns, schedule delays, and change order procedures. Insurance requirements, bonding provisions, and safety compliance responsibilities must be clearly outlined to protect all parties and ensure regulatory compliance.

Legal requirements in Canada

Canadian construction contracts must comply with provincial Construction Acts or Builder's Lien Acts, which govern payment procedures, lien rights, and holdback requirements. In Ontario, the Construction Act mandates specific payment timelines and adjudication processes, while other provinces have similar but distinct requirements under their Builder's Lien Acts. Your agreement must address Goods and Services Tax (GST) or Harmonized Sales Tax (HST) obligations under the Excise Tax Act, particularly regarding the tax treatment of reimbursable expenses. Workers' compensation coverage requirements vary by province and must be explicitly addressed in the contractor's obligations. Occupational Health and Safety Act compliance is mandatory, requiring specific safety protocols and protective equipment provisions. The agreement should include dispute resolution mechanisms that align with provincial construction legislation and ensure proper notice procedures for lien claims and payment disputes.
