Guide to Encapsulated Mass Timber Construction in the Ontario Building Code

The Guide to Encapsulated Mass Timber Construction in the Ontario Building Code – Second Edition is a comprehensive resource designed to help designers, code officials, and building professionals understand and apply the latest Ontario Building Code provisions for Encapsulated Mass Timber Construction (EMTC), effective January 1, 2025. Developed by the Canadian Wood Council / WoodWorks Ontario in collaboration with Morrison Hershfield (now Stantec), the guide explains the technical requirements, fire safety principles, and design considerations unique to EMTC, with clear references to relevant OBC articles. It covers everything from structural mass timber element specifications and encapsulation materials, to use and occupancy limits, mixed-use scenarios, and related provisions for structural design, environmental separation, and fire safety during construction. Intended to be read in conjunction with the Ontario Building Code, this is not a design guide, but rather a tool to distill complex regulations into practical, accessible information—equipping professionals to confidently design, review, and approve EMTC projects while ensuring compliance and optimizing performance. Notice of Correction: A previous version of this document contained a small error on page 19. In this electronic version of the document (updated August 12, 2025) the 3rd major bullet of Section 5.1.1 has been corrected.
