Marianne and Alison will bring you up to date on the latest claims against Municipalities, highlight red flags, and provide risk management tips for Building Departments.

Battery technologies have become an integral component of the modern built environment, with applications ranging from e-bikes and battery energy storage systems to electric vehicles. These widespread advancements introduce significant fire and explosion hazards and have modified the overall fire risk profile across building types, from single-family homes to complex structures. The presence of interconnected energy supply systems, such as solar panels, can further complicate this risk landscape. Addressing these challenges within the Canadian regulatory framework is multifaceted, involving the intersection of multiple codes and standards such as the OBC, OFC, and CEC. This presentation will examine these associated risks and outline fire management strategies for potential inclusion in the code framework, considering both Part 9 and Part 3 buildings.

Everyone acknowledges that we want to build homes faster and more affordably, but how do we do that? One of the best ways is with innovative building products. Hundreds of innovative building products enter the market every year, from space-age materials, to composite systems, to pre-fabricated panels, and more. But how do you know which products are code-compliant? The building
code’s prescriptive/acceptable solutions lag far behind innovation. In this session David will take you
behind the curtain of conformity assessment, into the world of innovative products, and show you how
the conformity assessment for code compliance blends expertise is materials and building science,
product testing and manufacturing, and more so you can feel confident approving innovative building
products in Ontario.
