CRN registration is a core component of the services we supply to our customers. We are Canada’s largest supplier of combined design and registration services. We have helped customers from around the world obtain over 2000 CRN numbers, many in multiple provinces.
Many companies that are expert in the pressure vessel field find that they can no longer successfully navigate Canada’s complex system which is increasingly varying between provinces, or even just between reviewers within a given province. Our services go beyond just handling paperwork – our in depth review process removes many issues prior to submission of documents. We also have the knowledge to help resolve many technical and procedural questions from jurisdictions on our own reducing the burden on our customers.
Canada’s CRN system is getting more difficult, more expensive and slower. Do you need expert help getting your products registered?
