This study examines the demand for mass timber and solid wood in Ontario under climate change scenarios. The use of mass timber and solid wood is important in reducing carbon emissions in construction, but sawmills and building developers are conservative due to uncertainties in supply and demand. In addition, different pathways of future economic and socioeconomic development could significantly affect the supply and demand of wood market. Therefore, this project investigates future wood demand in Ontario subject to multiple plausible scenarios in 21st century. The scenarios make use of established stumpage price system in Ontario to provide insights into potential market trends and inform decision making for not only forest sector but also and more specifically sawmills and building developers.
