Contractor prequalification in Canada: ISN, ComplyWorks and Avetta

April 24, 2026ยท5 min read

In much of Canadian industry, oil and gas, mining, utilities, large facilities, winning work depends not just on holding COR but on being prequalified through a contractor management platform. ISNetworld, ComplyWorks and Avetta are the ones you'll meet most often.

What they check

These platforms collect and grade your health and safety program: written policies and procedures, training records, insurance certificates, WCB/WSIB clearance, and your safety statistics (incident and lost-time rates). Owners set the pass mark, and a poor grade can quietly cost you the bid before you ever quote.

Where contractors lose points

The usual gaps are out-of-date documents, missing procedures for hazards the owner cares about, and statistics that can't be substantiated. Because grading is periodic and continuous, a program that was compliant last year can slip below the line without anyone noticing.

Keep it current, not annual

The contractors who stay prequalified treat it as a living system: policies reviewed, certificates renewed on time, training tracked, and stats kept accurate, so when the platform re-grades or an owner checks, everything's already there.

Questions, answered

Is ISNetworld the same as COR?

No. COR is a certification of your safety management system audited to a provincial standard. ISNetworld, ComplyWorks and Avetta are contractor-management platforms owners use to collect, grade and monitor your documents and statistics, often in addition to COR.

Why did our grade drop without anything changing?

Usually because a document expired, an owner added a new requirement, or your safety statistics moved. Grading is continuous, so currency matters as much as having the documents in the first place.

Be prequalification-ready

Complys keeps the policies, certificates, insurance and stats these platforms ask for in one place, always current, free for 30 days.
