This public comment period runs from December 8, 2023 to February 16, 2024.
What is this engagement about?
The Provinces of Quebec, Ontario and British Columbia are collaborating on a joint provincial task group that has developed proposed changes to further enable the use of Encapsulated Mass Timber Construction (EMTC) in Canada.
The Joint Task Group – Harmonized Variations for Mass Timber is soliciting technical feedback on proposed changes to enable EMTC for building occupancy types beyond the residential (Group C) and business and personal services (Group D) types currently permitted under the National Model Codes, to allow for taller EMTC buildings, and to vary the amount of encapsulation required in EMTC buildings.
What topics do the proposed code changes address?
The proposed code changes and their associated rationale, as developed and provided by the Joint Task Group – Harmonized Variations for Mass Timber, address the following topics:
- EMTC – Building heights for various occupancy types and encapsulation ratings
- Encapsulation of mass timber elements
- Encapsulation materials
- Combustible cladding
- Major occupancy fire separations
- Additional requirements for EMTC
How does this change relate to the National Model Code development process?
The proposed changes have been developed on an expedited basis to meet immediate provincial needs in a consistent way, and ahead of potential future consideration by the Harmonized Code Development System for the National Model Codes.
While the Canadian Board for Harmonized Construction Codes (CBHCC) has agreed to host this public comment period to amplify its reach as part of a pilot to foster harmonization, neither the CBHCC or its committees have reviewed the changes.
