Ontario Farm Boilers and Pressure Equipment Online Reports Now Online


Ontario greenhouse owners and operators can now report existing agricultural boilers and pressure vessels online.

The Technical and Safety Standards Authority (TSSA) rolled out the new online form on its website effective July 1, when new requirements came into effect under the Technical Standards and Safety Act 2000 Ontario Regulation 220/01: Boilers and Pressure Vessels and the Canadian Standards Association (CSA) B51: 19 Code for boilers, pressure vessels and pressure piping.

This applies to steam boilers, water boilers, pressure vessels and refrigeration equipment using ammonia, carbon dioxide, refrigerants of group A1 and all other refrigerants.

The deadline to submit the online form is September 30.

First announced last year, the exemption that was previously in place for agricultural BPVs was revoked last summer due to growing safety concerns. The TSSA published detailed requirements for boilers, pressure vessels (BPVs), fittings and piping used for agricultural purposes earlier this year. These requirements began on July 1, 2021.

The TSSA says it will use the information gathered to document existing devices in the province and conduct a risk-based assessment. In addition, they “will establish a priority list to plan an initial inspection over five years. The sites will be prioritized for a first inspection depending on the type of device, its location and whether it is covered by insurance. Priority for a first inspection will be given to farms with high risk sites.

Operators will be notified by email one month before the first inspection date. Those wishing to reschedule the first inspection should contact [email protected] or call 1-833-937-8772 (or 1-833-WFP-TSSA). TSSA will respond to questions sent to [email protected]

After September 30, any unreported site may incur additional charges for the owner.

The TSSA said it “will continue to work with agricultural partners to implement the new regulatory requirements. We will also work with BPV agricultural equipment insurers to ensure a smooth transition between the first TSSA inspection and periodic inspections by insurers, if applicable.

New installations

For new installations, a TSSA BPV inspector performs an installation inspection of all pressure equipment before it is put into service. If successful, the TSSA issues an inspection certificate (COI).

Once owners and operators have received a COI, certified equipment will then be subject to periodic inspection by a qualified inspector – owners should request an inspection either from their insurer or from the TSSA, as applicable, before the expiry date of their inspection certificate. More information is available online and a reference document here:

Manufacturers of pressure equipment must register their designs with the CTS, and designs must meet the requirements of the applicable North American code. Once approved, a Canadian Registration Number (CRN) is issued, which must be listed on the nameplate of each boiler and pressure vessel by the manufacturer. Manufacturers, manufacturers, contractors, assemblers or repair organizations of pressure equipment must have a valid certificate of authorization.

Existing installations

All existing and unregistered Boilers and Pressure Vessels (BPVs) that need to be repaired, modified, upgraded and / or replaced; and their associated piping systems, will be regulated on July 1. For more details, download the bulletin here:

The TSSA is currently developing a plan, which will be spread over five years, to bring all BPVs currently installed and used for agricultural purposes into compliance. The March 1 deadline for registering existing installations has been changed to July 1.
