General Construction Contract Template

A General Construction Contract is a bilateral contract between an Owner and a general / prime Contractor for the performance of construction work on a single project. Our free Canadian template is aware of Ontario's Construction Act as amended by Bill 216 and Bill 60 (in force 1 January 2026), Alberta's Prompt Payment and Construction Lien Act (in force 29 August 2022), British Columbia's Builders Lien Act, and Saskatchewan's Builders' Lien Act + Prompt Payment Construction Act. Built so that the contract is enforceable in every common-law province and addresses the high-stakes statutory traps — statutory holdback, lien preservation, prompt payment, change-order discipline, warranty, insurance and adjudication.

Contract: 850,000.00 CAD · Date: 2026-06-01
THIS GENERAL CONSTRUCTION CONTRACT (the "Contract") is made on 2026-06-01 between 180 Lake Shore Holdings Ltd. (the "Owner") and Maplewood Construction Group Inc. (the "Contractor"). The Owner wishes to engage the Contractor to perform the construction work described in this Contract on the project site located at 180 Lake Shore Boulevard East, Unit 100, Toronto, ON M5A 3X7, in the Province of Ontario, Canada (the "Project"). This Contract is governed by the Construction Act, R.S.O. 1990, c. C.30, as amended by the Construction Statute Law Amendment Act, 2024 (Bill 216) and Bill 60 (in force 1 January 2026).
1.
SCOPE OF WORK
The Contractor shall perform the following construction work (the "Work"):

Full interior fit-out of approximately 4,200 sq ft of ground-floor commercial space for a new restaurant tenant. Scope includes:
Demolition of existing fixtures and non-load-bearing partitions.
Mechanical, electrical and plumbing rough-in including new washrooms, kitchen exhaust hood, grease interceptor and 200-amp electrical service upgrade.
New partition walls, custom millwork (bar + service stations + banquettes), commercial kitchen equipment installation, finishes (porcelain tile, engineered hardwood, acoustic ceiling).
Fire-protection upgrade including new sprinkler heads and fire-alarm zone reconfiguration.
Final inspection and commissioning to Toronto Building Code occupancy permit.

The Work shall be performed in a good and workmanlike manner, in accordance with all applicable building codes, the Ontario Building Code or equivalent provincial code, all applicable bylaws, regulations and permits, and the plans and specifications (if any) annexed to this Contract.
2.
CONTRACT SUM
The Owner shall pay the Contractor the sum of 850,000.00 CAD for the complete performance of the Work (the "Contract Sum"). This amount is exclusive of GST / HST / PST, which shall be charged in addition at the applicable rate.
3.
TIME OF PERFORMANCE
The Contractor shall commence the Work on or before 2026-06-15 and shall achieve substantial performance of the Work (as that term is defined in the Construction Act, R.S.O. 1990, c. C.30, as amended by the Construction Statute Law Amendment Act, 2024 (Bill 216) and Bill 60 (in force 1 January 2026)) on or before 2026-12-15. Time is of the essence of this Contract.
4.
PAYMENT SCHEDULE
The Owner shall pay the Contract Sum on the basis of monthly progress draws on certified completion percentages.

Particulars:
Monthly progress draws based on a third-party Quantity Surveyor's certified percentage of work-in-place. Draws are submitted on the 25th of each month with payment within 28 days under the Construction Act prompt-payment scheme. The 10% statutory holdback is retained against each draw until released in accordance with the Annual Holdback Release clause below.
5.
STATUTORY HOLDBACK
The Owner shall retain a statutory holdback of 10% of the amount otherwise payable to the Contractor on account of each progress payment, in accordance with the Construction Act, R.S.O. 1990, c. C.30, as amended by the Construction Statute Law Amendment Act, 2024 (Bill 216) and Bill 60 (in force 1 January 2026). The holdback shall be released following the expiry of the applicable lien-preservation period, unless a lien has been preserved or perfected against the Project.

Annual holdback release (Ontario, 1 January 2026 amendments). For Projects spanning more than one (1) year, the Owner shall publish a notice of annual release of the accrued holdback within fourteen (14) days after each anniversary of the date of this Contract. The Owner shall then wait sixty (60) days from publication of the notice, after which the Owner shall release the accrued holdback to the Contractor within fourteen (14) days, unless a construction lien has been preserved or perfected against the Project.
6.
PROMPT PAYMENT
The Contractor may issue a "proper invoice" to the Owner at the intervals specified in this Contract (or, by default, monthly). A "proper invoice" must comply with the requirements of the Construction Act, R.S.O. 1990, c. C.30, as amended by the Construction Statute Law Amendment Act, 2024 (Bill 216) and Bill 60 (in force 1 January 2026). If the Owner does not deliver a written notice of non-payment within fourteen (14) days after receiving a proper invoice, the Owner shall pay the invoiced amount to the Contractor within 28 days after the proper invoice is received. The Contractor shall in turn pay each subcontractor the proportionate amount owing to that subcontractor within 7 days after receiving the corresponding payment from the Owner. Failure to comply with the prompt-payment timelines entitles the unpaid Contractor or subcontractor to interest at the rate prescribed by the Construction Act, R.S.O. 1990, c. C.30, as amended by the Construction Statute Law Amendment Act, 2024 (Bill 216) and Bill 60 (in force 1 January 2026) and, in Ontario, to refer the dispute to interim adjudication.
7.
LIEN PRESERVATION TIMELINES
The Parties acknowledge that any construction lien arising out of the Work must be preserved (registered against title to the Project) within 60 days from the earlier of (a) the date of substantial performance of the Work, (b) the date of completion or abandonment of the Work, and (c) the date the lien claimant last supplied services or materials to the Project, as those terms are defined in the Construction Act, R.S.O. 1990, c. C.30, as amended by the Construction Statute Law Amendment Act, 2024 (Bill 216) and Bill 60 (in force 1 January 2026). Failure to preserve a lien within the statutory window irrevocably extinguishes the lien rights and the unpaid party becomes an ordinary unsecured creditor.

Express acknowledgment by the Parties:
Both Parties acknowledge that the 60-day lien-preservation window under the Ontario Construction Act is a strict statutory deadline that cannot be extended by agreement or by the conduct of the Parties. The Contractor undertakes to track the lien-preservation deadline for every subcontractor and material supplier engaged on the Project.
8.
CHANGE ORDERS, WARRANTY, INSURANCE AND ADJUDICATION
Change orders. No change to the Scope of Work, the Contract Sum or the Time of Performance shall be valid unless documented in a written change order signed by both Parties. Changes with a Contract Sum impact below 5,000.00 CAD may be authorised verbally by the Owner's designated representative; changes at or above that threshold require a written change order signed by both Parties. The Contractor shall not proceed with any change without a valid change order, and the Owner shall not refuse to issue a change order for work the Owner has directed the Contractor to perform.

Warranty. The Contractor warrants the Work to be free from defects in materials and workmanship for a period of 24 months from the date of substantial performance. During the warranty period, the Contractor shall promptly remedy at its own expense any defect or deficiency in the Work, exclusive of fair wear and tear and damage caused by the Owner's misuse. This warranty is in addition to (and not in substitution for) any new-home warranty required by provincial law (Tarion Warranty Corporation in Ontario; Travelers Canada / National Home Warranty in BC; New Home Buyer Protection in Alberta).

Insurance. Throughout the performance of the Work and through the warranty period, the Contractor shall maintain in good standing: (a) Commercial general liability insurance with an inclusive limit of not less than 5,000,000.00 CAD per occurrence; (b) all-risks builders risk insurance covering the full replacement value of the Work, naming the Owner as additional insured; (c) any provincial workers' compensation coverage required by law (WSIB in Ontario, WorkSafeBC in BC, WCB-Alberta); (d) any motor-vehicle insurance required for vehicles used in performance of the Work. The Contractor shall provide a current certificate of insurance to the Owner before commencing the Work and on each renewal.

Adjudication. Any dispute arising under this Contract relating to a proper invoice, a notice of non-payment, a payment of holdback, services or materials supplied or to be supplied, a payment under a subcontract, a change order or any matter related to the prompt-payment scheme, may be referred by either Party to interim adjudication under the Construction Act, R.S.O. 1990, c. C.30, as amended by the Construction Statute Law Amendment Act, 2024 (Bill 216) and Bill 60 (in force 1 January 2026). The adjudicator's determination is binding on the Parties on an interim basis pending final resolution by agreement, mediation, arbitration or court order.
9.
TERMINATION FOR CAUSE
Either Party may terminate this Contract for cause on five (5) Business Days' written notice if the other Party (a) commits a material breach of this Contract that is not cured within those five (5) Business Days, (b) becomes insolvent, files for bankruptcy or makes an assignment for the benefit of creditors, (c) abandons the Work for more than five (5) consecutive Business Days without reasonable excuse. On termination, the Owner shall pay the Contractor for Work properly performed up to the date of termination (less any setoff for the Owner's damages), and the Contractor shall promptly remove its equipment from the Project site and provide the Owner with any drawings, specifications and shop drawings relating to the Work.
10.
GOVERNING LAW
This Contract shall be governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein, including the Construction Act, R.S.O. 1990, c. C.30, as amended by the Construction Statute Law Amendment Act, 2024 (Bill 216) and Bill 60 (in force 1 January 2026).

What Is a General Construction Contract?

A General Construction Contract is a written contract between the Owner (who commissions the work) and the general or prime Contractor (who performs and coordinates the work) for the performance of construction work on a single defined project. It records the scope of work, the contract sum, the time of performance, the payment schedule, and the statutory protections that apply under the construction-lien legislation of the project's province.

Every Canadian common-law province has a construction-lien statute that imposes a mandatory statutory holdback (typically 10 percent; 7.5% in Manitoba; 20% in New Brunswick and PEI) and a strict lien-preservation period (60 days in Ontario, Alberta, Nova Scotia, New Brunswick, PEI; 45 days in BC; 40 days in Saskatchewan and Manitoba; 30 days in Newfoundland and Labrador). Missing the lien-preservation period irrevocably extinguishes the lien claim — the unpaid party becomes an ordinary unsecured creditor with no priority against the Project.

Ontario, Alberta and Saskatchewan now operate a statutory prompt-payment scheme in addition to the lien regime. The Owner has 28 days to pay a "proper invoice" (or to deliver a written notice of non-payment within 14 days); the Contractor must pay each subcontractor the proportionate amount within 7 days. Failure to comply attracts statutory interest and an entitlement to interim adjudication by an Ontario Dispute Adjudication for Construction Contracts (ODACC) adjudicator or a private adjudicator. Effective 1 January 2026, Ontario added a new annual holdback release procedure (notice within 14 days of each contract anniversary, 60-day wait, 14-day release) for projects spanning more than one year.

How to Create Your General Construction Contract

Follow these steps to prepare a contract that is enforceable and that protects both Owner and Contractor against the typical construction-lien and prompt-payment traps.

  1. 1

    Identify the Project Province First

    Each province has its own construction-lien statute with different holdback percentages, lien-preservation timelines and prompt-payment availability. The Expert tier auto-applies the correct province-specific timelines once the province is selected.

  2. 2

    Describe the Scope of Work in Detail

    The scope description determines change-order entitlement. Vague scope = expensive scope-creep dispute. Use specific, measurable scope items, one per line.

  3. 3

    Set the Contract Sum and Tax Treatment

    Be explicit about GST / HST / PST — inclusive vs exclusive. Most commercial contracts are exclusive (taxes added at invoice), most consumer renovations are inclusive (single all-in price).

  4. 4

    Choose a Payment Schedule

    Monthly progress draws against certified percentage of work-in-place is the standard for projects > $100k. Milestone-based for fixed-deliverable projects. Lump-sum-on-completion only for small projects (< $25k) where the Contractor can absorb the financing.

  5. 5

    Add Statutory Holdback (Expert)

    Province-aware: 10% in ON/AB/BC/SK/NS/NL; 7.5% in MB; 20% in NB/PEI. For Ontario projects > 1 year, add the new 2026 annual-release procedure (14-day notice, 60-day wait, 14-day release).

  6. 6

    Add Prompt Payment (ON/AB/SK only) (Expert)

    Statutory 28-day owner-to-GC + 7-day GC-to-sub. Default values for those provinces; not applicable to BC, MB, NS, NB, NL or PEI.

  7. 7

    Add Lien Preservation Acknowledgment (Expert)

    Express Party acknowledgment that the strict 60-day (or 45 / 40 / 30) lien-preservation window cannot be extended by agreement. Contractor undertakes to track the deadline for every subcontractor.

  8. 8

    Add the Protection Quad (Expert)

    Change orders (written, with threshold for verbal authorisation), warranty (12-24 months), insurance ($2M CGL minimum, builders risk, provincial workers' comp), adjudication (ON/AB/SK).

Legal Considerations

Construction contracts are governed by an overlay of provincial construction-lien legislation, prompt-payment legislation, common-law contract principles and the applicable provincial building code.

This template is for informational purposes only and does not constitute legal advice. Construction contracts carry significant lien, prompt-payment, holdback and warranty consequences. Consult a qualified Canadian construction lawyer for advice specific to your project, particularly where the project involves public infrastructure, mining, energy or any matter that engages the OPP, federal Crown corporations or where the contract sum exceeds $1 million.

Reviewed for Canadian common-law-province requirements

Ontario Construction Act (Bill 216 + Bill 60 + 1 January 2026)

The Ontario Construction Act, R.S.O. 1990, c. C.30, was substantially amended by the Construction Statute Law Amendment Act, 2024, S.O. 2024, c. 27 (Bill 216), and by Bill 60. The amendments came into force on 1 January 2026. The key changes are: (a) annual holdback release for projects spanning more than one year (notice within 14 days of each contract anniversary, 60-day wait, 14-day release); (b) prompt-payment improvements including redefined "proper invoice" and the option of private adjudicators alongside the ODACC roster; (c) prospective application to contracts entered into on or after 1 January 2026 (for older contracts, annual release begins on the second anniversary after 1 January 2026).

Alberta Prompt Payment and Construction Lien Act

On 29 August 2022, the Prompt Payment and Construction Lien Act, R.S.A. 2000, c. P-26.4 ("PPCLA") replaced the previous Builders' Lien Act. The PPCLA maintains the 10 percent statutory holdback but extends the lien-preservation deadline from 45 days to 60 days for general work and to 90 days for work related to concrete (to reflect the time required for concrete to cure). The PPCLA adds a prompt-payment scheme similar to Ontario: 28-day owner-to-GC, 7-day GC-to-sub, statutory notice of non-payment, interim adjudication.

British Columbia Builders Lien Act

The Builders Lien Act, S.B.C. 1997, c. 45, imposes a 10 percent statutory holdback and a strict 45-day lien-preservation period from the date of substantial performance, completion or last supply of services or materials. BC does not (as at the date of this template) operate a prompt-payment scheme — payment timelines and dispute mechanisms are governed by the negotiated contract terms.

Saskatchewan Builders' Lien Act + Prompt Payment Construction Act

Saskatchewan operates a dual regime: The Builders' Lien Act, S.S. 1984-85-86, c. B-7.1 (10 percent statutory holdback, 40-day lien preservation) is supplemented by The Prompt Payment Construction Act, S.S. 2024, c. 22 (in force 1 March 2024), which imports a prompt-payment scheme materially identical to Ontario's (28-day owner-to-GC, 7-day GC-to-sub, adjudication).

Other Provinces

Manitoba — The Builders' Liens Act, C.C.S.M. c. B91: 7.5 percent holdback, 40-day lien. Nova Scotia — Builders' Lien Act, R.S.N.S. 1989, c. 277: 10 percent holdback, 60-day lien. New Brunswick — Mechanics' Lien Act, R.S.N.B. 1973, c. M-6: 20 percent holdback, 60-day lien. Newfoundland and Labrador — Mechanics' Lien Act, R.S.N.L. 1990, c. M-3: 10 percent holdback, 30-day lien. PEI — Mechanics' Lien Act, R.S.P.E.I. 1988, c. M-4: 20 percent holdback, 60-day lien. None of these provinces yet operate a prompt-payment scheme.

Provincial Workers' Compensation

Every province requires construction contractors to maintain provincial workers' compensation coverage. Ontario: WSIB (Workplace Safety and Insurance Board) under the Workplace Safety and Insurance Act, 1997. BC: WorkSafeBC under the Workers Compensation Act, R.S.B.C. 2019, c. 1. Alberta: WCB-Alberta under the Workers' Compensation Act, R.S.A. 2000, c. W-15. Coverage status must be verifiable by a Clearance Certificate before any payment is released; failure to maintain coverage exposes the Owner to liability for the Contractor's claims.

Provincial New-Home Warranty

For residential construction, the contractor warranty in this contract is layered over the mandatory provincial new-home warranty: Tarion Warranty Corporation in Ontario (under the Ontario New Home Warranties Plan Act); Travelers Canada or National Home Warranty in BC (Homeowner Protection Office); New Home Buyer Protection in Alberta (NHBPA registry, mandatory under the New Home Buyer Protection Act, S.A. 2012, c. N-3.2). Commercial construction is not subject to a statutory new-home warranty regime.

Quebec — Excluded From This Template

Quebec is governed by a separate civil-law construction regime under the Civil Code of Québec (articles 2118-2129 prestation de services et entreprise) and the Loi sur les architectes. A Quebec-specific template will follow in a future sprint.
