Developers and project teams are increasingly being asked to deliver lower-carbon, faster-to-market housing, while system selection decisions are often made amid uncertainty around cost, risk, and constructability. Drawing on Urban Equation’s experience with Windmill’s Hälsa project, the session shares insights from a completed market and viability study, alongside a like-for-like cost and schedule comparison for a planned 12-storey, 159,000-sf project case study in Ottawa. This session will examine when modular mass timber makes financial sense for multi-residential development, and when it does not. A direct comparison of Intelligent City’s Cross-Laminated Timber (CLT) system with cast-in-place concrete will shed light on where costs truly shift, where schedule and financing efficiencies are realized, and how labour availability, material volatility, and preferential funding influence adoption decisions. The session also offers a national perspective on the policy, financing, and industry conditions required to accelerate CLT adoption and mature Canada’s mass-timber market.
