The sudden collapse of excavation walls or trench sides onto workers below. Under provincial OHS regulations, subcontractors must implement protective systems before personnel enter any excavation deeper than 1.2 metres. Failure to comply can result in work stoppages, fines, and serious liability exposure.

A flammable hydrocarbon fuel—primarily propane or butane—stored under pressure and commonly used onsite for heating, cutting, and equipment operation. Subcontractors handling LPG must comply with Transport Canada and provincial regulations for storage, transport, and handling. Proper training and certifications are typically required before field crews can work with LPG systems.

Data ownership defines who legally controls field data collected during a job — such as inspection reports, equipment readings, or site photos. Contracts often assign ownership to the client, limiting a subcontractor's right to reuse or retain that data. Review ownership clauses carefully before signing to protect your company's records and liability position.

A formal written authorisation required before performing any work that produces heat, sparks, or open flame on a job site. Subcontractors must obtain this permit before welding, cutting, or grinding near flammable materials. Site supervisors issue and sign off on these permits, and work must stop if conditions change.

A licence that requires the holder to carry a surety bond as financial assurance that they will meet regulatory obligations, meaning subcontractors and field service companies must maintain this bond coverage to legally operate certain equipment or perform specific scopes of work on a client's site. For subcontractors, holding a bonded operator licence is often a prerequisite for bidding on contracts, as it signals to operators and general contractors that financial accountability is in place if work standards or regulatory requirements are not met.

A government-issued agreement granting a company the right to explore or extract resources on federally managed land. Subcontractors working on these sites must meet stricter regulatory and documentation requirements. Expect additional compliance checks, environmental controls, and reporting obligations on federally leased projects.
