Contracts

Construction pricing is determined exclusively by contract; legislation governs payment timing and remedies, not price calculation or price reasonableness.

General contract law

Prompt Payment and Adjudication legislation (where applicable)

Builders’ / Construction Lien legislation

No statutory pricing formulas, benchmarks, unit rates, or productivity standards exist.

Price disputes arise from an unclear or inconsistent pricing basis (hourly vs unit price vs lump sum).

Change orders are contractual instruments; legislation governs payment timing and enforcement, not valuation or pricing methodology.

Prompt Payment and Adjudication legislation (where applicable)

General contract law

Methods for valuing changes are often undefined in advance or agreed only after work is performed.

Unpriced or ambiguously priced changes cause delayed payment, scope disputes, work suspension, or litigation.

Construction timelines are governed exclusively by contract; legislation addresses delay consequences and payment remedies indirectly, not scheduling standards or productivity benchmarks.

General contract law

Prompt Payment and Adjudication legislation (where applicable)

Builders’ / Construction Lien legislation

No statutory definition of reasonable construction timelines, baseline schedules, or productivity-based planning standards.

Delays become disputable due to undefined baseline schedules, unclear responsibility allocation, and poorly drafted delay provisions.

Construction liability and insurance are governed primarily by contract and general law; legislation sets minimum statutory obligations but does not prescribe risk allocation or insurance adequacy for specific scopes of work.

Occupational Health and Safety legislation

Provincial insurance law

Legislation does not define how liability must be allocated among project participants or what insurance types and limits are appropriate for a given scope of work.

Unclear liability allocation and inadequate insurance lead to uninsured losses, contractual disputes, and potential personal exposure.

Termination 

Termination of construction contracts is governed by contract terms and general contract law; legislation does not prescribe mandatory grounds, procedures, or consequences for termination.

General contract law

Construction / Builders’ Lien legislation

Prompt Payment and Adjudication legislation (where applicable)

Contracts often lack clear termination triggers, notice requirements, cure periods, and defined post-termination consequences.

Unclear termination provisions lead to disputes over payment entitlement, damages, demobilization costs, and responsibility for completing the work.

Construction dispute resolution is governed by contract terms and applicable legislation; no single mandatory process applies to all construction disputes.

General contract law

Prompt Payment and Adjudication legislation (where applicable)

Builders’ / Construction Lien legislation

Provincial civil procedure rules

Contracts often fail to define a clear dispute pathway, escalation sequence, or coordination between adjudication, lien remedies, and court proceedings.

Poorly defined mechanisms cause delays, higher legal costs, procedural inefficiency, and parallel proceedings.

Unclear governing law causes disputes over applicable statutes, remedies, limitation periods, and procedural rules.

Contracts rarely specify concrete consequences for undefined scope, delays, or disputed changes beyond general legal remedies.

Where consequences are undefined, outcomes are determined case-by-case through adjudication or court proceedings.
