Boiler & Pressure Vessel Compliance
Boilers and pressure vessels carry their own century-old safety regime: design registration (CRNs), installation permits, periodic inspections with certificates, and — above power thresholds — certified operators. Alberta’s ABSA, Ontario’s TSSA, Saskatchewan’s TSASK and provincial branches elsewhere run the programs, and an expired certificate of inspection is a genuine shut-down offence, not paperwork trivia.
What owners must keep current
Registered vessels require periodic inspection — internally and externally on schedules set by class and service — with the certificate of inspection posted or filed. Heating boilers in apartment and commercial buildings, compressed-air receivers in shops, and refrigeration pressure equipment all commonly fall in scope; owners are frequently unaware their air receiver is a registered vessel at all until an inspector or insurer asks.
Operators and logs
Above provincial thresholds (measured in boiler horsepower/kW and pressure), plants require certified operating engineers, with class requirements scaling by plant size. Modern low-water-cutoff and automation rules have relaxed attendance for some plants — knowing where your plant actually sits often saves staffing money or reveals an exposure.
Insurance interplay
Boiler & machinery insurers conduct their own jurisdictional inspections in several provinces, acting as authorized inspection agencies. Coordinating authority, insurer and maintenance schedules into one calendar is most of what “compliance” means here — and what we set up.
How the process works
- Inventory: tell us or let us survey what pressure equipment exists on site.
- We verify registration and inspection status with the provincial authority.
- Overdue inspections are booked; deficiencies quoted and corrected.
- Operator requirements are assessed against plant ratings.
- A unified inspection calendar keeps every certificate current going forward.

Frequently asked questions
Does my apartment building’s heating boiler need inspections?
Almost certainly, above small domestic sizes — periodic authority or insurer-jurisdictional inspections with certificates. Ask when it was last inspected; if nobody knows, that is the answer.
What is a CRN?
A Canadian Registration Number proving a vessel or fitting design is registered for use in that province. Equipment imported without CRNs — a common online-purchase mistake — cannot legally be installed.
Do I need a stationary engineer on staff?
Only above thresholds that vary by province and plant automation. Many owners either overstaff from old habit or understaff from ignorance; a ratings review answers it definitively.
What about my compressor’s air tank?
Receivers above modest size/pressure thresholds are registered vessels requiring inspection in most provinces. Shops discover this during insurer surveys — better to discover it deliberately.
