Where can I find a qualified Building Code Designer? 

The Building Code Act requires that a range of individuals and firms responsible for design activities regulated under the Act be qualified in their appropriate area of design and, when required, registered with the Province. Individuals and, in some instances, their firms must file with the Ministry of Municipal Affairs and Housing to obtain a Building Code Identification Number (BCIN).

The Ministry’s Qualification and Registration Tracking System (QuARTS) includes a public registry of qualified designers and registered firms.

For more information about the Ontario Building Code in general, visit the Ministry of Municipal Affairs and Housing website at

For certain projects, such as most industrial / commercial / institutional construction, a qualified or registered designer is not sufficient and the drawings must be stamped by an architect, professional engineer or both. Refer to Division C, Section 1.2 of the Building Code for specific requirements, or contact the Building Department. The seals and signatures of architects and professional engineers are required to be original on at least one set of drawings. Please refer to the Town of Tillsonburg permit application requirements for additional information.
