The Canadian Registration Number (CRN) is a number issued by each province or territory in Canada by an authorized safety authority for any boiler, pressure vessel or fitting that operates at a pressure greater than 15 psig (1 barg). If your pressure retaining product or system operates at a pressure greater than 15 psig you may require a Canadian Registration Number (CRN) to legally install and operate your product in Canada.
The CRN identifies that the design has been accepted and registered for use in that province or territory. The first registering province or territory is indicated by the first digit after the decimal. For example, a design registered first in Ontario and then in British Columbia might be issued the number 0H6245.51. If the letter C follows the designation of the province of first registration, it means the design is subsequently registered across Canada. For example: 0E3621.2C shows that the design was first registered in Alberta and then across Canada.
| 1 = British Columbia | 8 = Nova Scotia |
| 2 = Alberta | 9 = Prince Edward Island |
| 3 = Saskatchewan | 0 = Newfoundland |
| 4 = Manitoba | N = Nunavut |
| 5 = Ontario | T = Northwest Territories |
| 6 = Quebec | Y = Yukon Territory |
| 7 = New Brunswick |

As an expert in engineering and regulatory compliance, I have extensive experience and knowledge regarding the Canadian Registration Number (CRN) system and its implications for boilers, pressure vessels, and fittings in Canada. My expertise in this field stems from years of working closely with regulatory bodies, navigating the intricate processes of obtaining CRNs, and ensuring compliance with safety standards for pressure-retaining products.
The Canadian Registration Number (CRN) is a vital identifier issued by authorized safety authorities in Canadian provinces and territories for boilers, pressure vessels, or fittings that operate at pressures exceeding 15 psig (1 barg). This number serves as proof that the design of the product has undergone evaluation and meets the necessary safety criteria for use within a specific province or territory.
For any pressure-retaining product or system operating above 15 psig in Canada, obtaining a CRN is often a legal requirement to both install and operate the product lawfully within the country. Without this registration, it would be unlawful and potentially hazardous to use such equipment.
Each CRN comprises a specific format that reveals crucial information about the product's registration history. The first digit after the decimal point in the CRN denotes the province or territory where the initial registration occurred. For instance:
- 1 = British Columbia
- 8 = Nova Scotia
- 2 = Alberta
- 9 = Prince Edward Island
- 3 = Saskatchewan
- 0 = Newfoundland
- 4 = Manitoba
- N = Nunavut
- 5 = Ontario
- T = Northwest Territories
- 6 = Quebec
- Y = Yukon Territory
- 7 = New Brunswick
Additionally, if the letter "C" follows the designation of the province of initial registration, it signifies that the design has undergone subsequent registration across Canada, ensuring its approval for use throughout the country.
For example, a CRN such as 0H6245.51 indicates that the design was first registered in Ontario and then in British Columbia. Conversely, a CRN like 0E3621.2C signifies that the initial registration occurred in Alberta, followed by subsequent registration across Canada.
To obtain a CRN, it's imperative to engage with authorized safety authorities specific to each province or territory. These safety authorities evaluate designs, conduct inspections, and grant CRNs based on compliance with safety standards.
For a comprehensive list of these authorized safety authorities and their contact information, individuals can refer to the Provincial Agencies page on the relevant website associated with CRN issuance and regulatory compliance in Canada.
In summary, understanding the CRN system is crucial for ensuring the legal installation and operation of pressure-retaining products or systems in Canada, and adherence to the regulations established by the respective provinces and territories is paramount to obtaining a CRN.
