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.

Across the building sector, expectations for speed, clarity, and consistency in regulatory processes are rapidly evolving. At the same time, the complexity of building codes, regulations, and compliance pathways continues to grow.
In this session, the Trax team will share an early look at a new set of tools designed to support building officials in navigating and applying regulatory requirements. Without revealing full details ahead of release, this preview will highlight emerging approaches to structuring and working with regulatory information in practice.

Green roofs have evolved from specialty features to mainstream building‑envelope systems, driven in part by their stormwater‑management benefits. In this session, Ginkgo will break down the main types of green roofs, their functions and advantages, and the performance standards that guide their use. The presentation will also highlight how proper design, construction, and maintenance are essential to ensuring public health and safety.

Urban development is increasingly constrained by diminishing building lot sizes, necessitating a significant rise in the use of earth retaining structures for light residential and commercial applications. As urban areas continue to grow and available land becomes scarcer, developers are compelled to maximize the utility of smaller plots, leading to heightened demand for innovative civil engineering solutions. Among these solutions, the implementation of earth retaining structures has become prominent for stabilizing soil and preventing erosion and control drainage. The adoption of mid-size segmental and mechanically stabilized earth (MSE) walls has emerged as a preferred approach due to their versatility, cost-effectiveness, and ability to accommodate various design requirements.
This session will explore the application of earth retaining structures in light residential and commercial contexts, emphasizing both civil and geotechnical design considerations and the lack of design requirement in the current building code. The session will cover current design practice and compare different design codes and manual used across Canada and the United States. Case studies of past and ongoing projects will illustrate different design considerations and practical applications, highlighting successful implementations and lessons learned from projects that encountered unforeseen challenges. By analyzing real-world examples, attendees will gain insights into best practices and innovative approaches applicable to future projects.
