What’s New in NBC 2025: Key Code Changes Shaping Residential Construction

The 2025 National Building Code of Canada introduces important updates that will directly influence how homes are designed, built, and evaluated across the country. From enhanced radon protection and evolving window performance requirements to new energy provisions, operational GHG considerations, and updated approaches to lateral loads, these changes signal a continued shift toward healthier, more durable, and higher-performing homes.

Join Mark Rosen for a practical, industry-focused discussion with Frank Lohmann, Director of Building Science at the Canadian Home Builders’ Association, and Mike Memme of Mountainview Building Group. Together, they will walk through the most impactful NBC 2025 changes affecting residential construction and share perspectives on what they mean in practice for builders, designers, and building officials.

This session will help housing professionals understand not just what has changed, but why it matters — and how to prepare for implementation as the new code begins to shape projects on the ground.
