What is CSTS 2020?
CSTS 2020 (Construction Safety Training System 2020) is Alberta's foundational construction safety orientation course, administered by the Alberta Construction Safety Association (ACSA). It is the updated version of the original CSTS-09 course and covers essential safety topics including hazard identification, personal protective equipment, emergency response, and workers' rights and responsibilities under Alberta's OHS legislation. CSTS 2020 is the entry-level safety certification required by virtually all construction employers in Alberta.
Nearly every worker entering a construction site in Alberta is required to hold a valid CSTS 2020 certificate. This includes labourers, tradespeople, supervisors, engineers, and even visitors who spend time on active construction sites. Many general contractors and project owners list CSTS 2020 as a minimum requirement for site orientation, alongside other certifications like WHMIS and First Aid.
Why Expiration Tracking Matters
CSTS 2020 certificates are valid for 3 years from the date of completion. In Alberta's construction industry, showing up to a site with an expired CSTS means being turned away — no exceptions. General contractors performing site orientations will check CSTS validity as one of the first items. An expired CSTS can delay project timelines, cost workers a day's wages, and create scheduling headaches for employers managing crews across multiple sites.
The Cost of Non-Compliance
Ontario — OHSA
$2,000,000
Max fine per offence, corporations
$1,500,000
Max fine, directors & officers
$500,000
Max fine, individuals — plus up to 12 months imprisonment
An expired certificate is not a paperwork slip: a worker with lapsed required training (e.g. Working at Heights) is an untrained worker, and letting them work is an offence for both employer and constructor. Since 2025, inspectors can also issue administrative monetary penalties directly, without a prosecution.
Statutory maximums as of 2026 · OHSA Part IX — Offences and Penalties. Regimes and amounts vary by jurisdiction and case; this is general information, not legal advice.
Provincial Requirements & Regulations
CSTS 2020 is specific to Alberta and is recognized as the standard construction safety orientation by Alberta's OHS system. While other provinces have their own safety orientation programs (for example, Ontario's Basic Occupational Health and Safety Awareness Training), CSTS 2020 is uniquely Alberta's industry-standard course. Some national companies operating in Alberta accept CSTS 2020 for their Alberta projects while requiring different certifications in other provinces. Workers moving between provinces should verify which safety orientation is required at each job site.
Renewal Process
Workers must retake the CSTS 2020 course every 3 years. There is no separate refresher — the full course must be completed again. CSTS 2020 is available both in-classroom and online through ACSA-approved providers. The online course typically takes 6-8 hours to complete. Workers receive a new certificate with a new 3-year expiry date upon successful completion.
Common Mistakes to Avoid
- Assuming the old CSTS-09 certificate is still accepted — CSTS 2020 replaced it and is now the required version
- Waiting until the last minute to renew — online courses still take 6-8 hours to complete
- Not carrying proof of CSTS on your first day at a new Alberta site — you will be turned away
- Thinking CSTS from one provider is different from another — all ACSA-approved courses cover the same standardized content
