What’s new in CAN/ULC‑S536‑19 (Ontario 2026)

• Deeper, device‑level testing. More steps for control units, power supplies, voice systems, wireless/air‑sampling/CO devices, & circuit supervision.
• New battery test method. Moves beyond a simple voltage check to a load/functional test with recorded values.
• Mandatory report forms. The standard’s official annual & monthly forms are now required—no abridged checklists.
• Clear deficiency vs. recommendation. Deficiencies must be corrected; recommendations are optional improvements.
• Attendance & accountability. Technician names, dates, times on site recorded; owner acknowledgment captured.
• Monthly logs formalized. A defined form/log for monthly checks is part of your compliance record.

S536‑19 vs S536‑13: what actually changes

What this means for owners & property managers (Toronto & Ontario)

Operational changes

• Longer service windows. Allow more time per annual inspection; complex sites may span multiple visits.
• Suite access planning. Device‑level testing increases the need for coordinated entry in residential towers.
• Monthly discipline. Ensure monthly checks are done and logged on the correct form.

Budget & contracts

• Expect higher inspection effort. Many portfolios see ~20–35% more labor/time under S536‑19.
• Update service agreements. Specify compliance with CAN/ULC‑S536‑19 & delivery of the official report forms.
• Allocate for fixes. Deeper testing finds more issues; set aside funds to clear deficiencies quickly.

Risk & governance

• Fewer gray areas. Deficiencies are unambiguous—and must be corrected.
• AMPs (fines) possible. AHJs can issue penalties for missed/insufficient inspections and uncorrected hazards.
• Insurance readiness. Clean, standardized reports support underwriting and claims.

Scheduling & budget planning (at‑a‑glance)

Your 6‑step plan

1. Map your portfolio (panels, device counts, access needs).
2. Pre‑book 2026 inspection windows now to avoid capacity crunch.
3. Train/build policy for monthly checks with the new log.
4. Prepare documents (see list below) in a single binder/cloud folder.
5. Close deficiencies fast and capture proof of correction.
6. Align budgets for longer inspections & likely remedial work.

Documentation you must keep on‑site (and show on request)

• Annual inspection report (CAN/ULC‑S536‑19 official form)
• Monthly inspection logs (official monthly form)
• Verification certificate for new/altered systems (CAN/ULC‑S537‑19)
• Device lists & as‑built drawings (panel program printouts help)
• Battery test records with measured values
• Deficiency list & proof of correction (work orders, invoices, re‑tests)
• Monitoring certificates & contact details
• Fire Safety Plan updated to reflect new procedures

Compliance, AMPs & liability

Why it matters: after incidents, investigators review your latest ULC‑S536 report. A documented unresolved deficiency can raise liability. Conversely, a complete, clean file demonstrates due diligence.
