For over 20 years, our team has helped businesses across Ontario handle the complex regulations around pressure vessels, piping systems, boilers, and fittings, making compliance straightforward and efficient.

Understanding TSSA Registration & CRN Compliance in Ontario

Operating pressure equipment in Ontario requires strict adherence to provincial safety regulations. TSSA registration makes sure that boilers, pressure vessels, piping systems, and fittings meet the standards necessary for safe operation. CRN certification complements this by confirming that your equipment design satisfies both provincial and national safety codes.

At Titan Research Group, we specialize in helping Ontario businesses with these regulatory requirements. With over two decades of experience, we manage every step, from design verification to documentation and regulator coordination, so your equipment meets all legal and safety obligations, allowing you to focus on your operations without regulatory concerns.

FAQs About TSSA & CRN Compliance in Ontario

What types of pressure equipment require TSSA registration in Ontario?
TSSA registration applies to boilers, pressure vessels, piping systems, fittings, and other pressure-retaining equipment used in commercial or industrial applications.
How long does it take to complete CRN registration in Ontario?
The timeline depends on the complexity of the design, required testing, and regulatory review, but Titan Research Group helps with the entire process for faster approvals.
Are CRN and TSSA registration the same thing?
No. CRN is a unique number assigned to pressure equipment after design approval, while TSSA registration verifies that equipment meets Ontario-specific safety and operational regulations.
Can unlisted pressure equipment get a CRN in Ontario?
Yes. Unlisted equipment can be submitted for CRN approval, often requiring engineering review, testing, and documentation to meet ASME, CSA, and TSSA standards.
What role does testing play in TSSA compliance?
Hydrostatic, burst, proof, and leak testing validate that pressure vessels and piping systems meet MAWP, safety, and design requirements for TSSA approval.
Are there renewal requirements for TSSA registration and CRN?
Yes. Equipment registration may require updates or renewals if there are design changes, new installations, or changes in provincial regulations.
Do all provinces in Canada have the same CRN requirements as Ontario?
No. Each province has specific rules and safety authorities. TSSA oversees Ontario, but requirements may differ in BC, Alberta, or Quebec.
Can you help with TSSA inspections?
Absolutely. Our engineers and QA specialists can prepare documentation, support inspections, and coordinate with TSSA to confirm full compliance.
What standards are referenced for pressure equipment in Ontario?
TSSA often references ASME Boiler and Pressure Vessel Codes, CSA standards, and applicable provincial safety regulations when reviewing designs and issuing CRNs.
Can companies perform CRN registration and TSSA compliance themselves?
While possible, the process is complex. Working with experienced engineers and regulatory experts, like Titan Research Group, helps avoid errors, delays, and costly resubmissions.
