Canadian Registration Numbers
Provincial Registration and Its Lead Time
Pressure equipment installed in Canada requires a Canadian Registration Number, and registration is granted provincially rather than nationally. A design registered in one province is not automatically registered in another.
It is a design registration, not a unit certificate. The CRN attaches to the design, so a registered model can be supplied repeatedly against that registration. Where a catalogued model is already registered in the destination province, the process is simply a matter of quoting the number.
Where it is not already registered, it takes time. Registration proceeds at the pace of the provincial authority, and that pace is outside the fabricator's control. It is the single most common reason a finished exchanger waits before shipping to a Canadian site.
ASME construction does not remove the requirement. An ASME-stamped and National Board registered vessel still needs a CRN for Canadian installation. The two systems are complementary rather than alternatives.
Raise it at enquiry. Tell us the destination province with the enquiry rather than with the order. If a registered model covers the duty, the schedule is unaffected. If it does not, knowing early is what protects the programme.
CRN Practicalities
Registration is provincial and attaches to the design rather than the individual unit.
What It Is
- Requirement: Pressure equipment in Canada
- Scope: Provincial, not national
- Attaches to: The design
- Relationship to ASME: Additional, not alternative
Affects
- Delivery schedule where not pre-registered
- Which catalogued models can be supplied
- Documentation package
- Province by province
- Design changes requiring re-registration
Tell Us Early
- Destination province
- Whether a registered model is acceptable
- Programme dates
- Any design deviation required
- Whether ASME is also specified

Raise It at Enquiry, Not at Order
Registration Is Not on the Critical Path If You Plan for It
Where a catalogued model is already registered in the destination province, supplying against that registration adds nothing to the schedule. The problem arises only when a unit is ordered, fabricated and then found to need a registration nobody applied for.
Tell us the province with the enquiry. If a registered model covers the duty we will say so, and if it does not we will tell you what the registration is likely to add before you commit to a programme date.
A Design Change Can Reset It
Because the CRN attaches to the design, a deviation from a registered model may require the deviation to be registered. That includes changes that seem minor, such as a nozzle relocation or a different pass arrangement.
Where the schedule is tight, staying within a registered configuration is frequently worth more than the convenience the deviation would have provided.
