With summer temperatures reaching peak levels, our local Vale of Avoca ravine continues to provide a natural refuge for Deer Park residents doing their best in the heat. This underlines the importance of longer-term actions to address erosion of the ravine’s slopes and creek channel, and the dilapidated state of the park’s trail network.
Measures leading to rehabilitation of the ravine will soon be entering a more active phase. The City of Toronto has recently awarded a contract for the development of a master plan for the ravine to engineering, architectural and environmental consultancy GHD. Australia-based GHD has extensive operations across Canada.
GHD offers a strong set of interdisciplinary capabilities, which is critical for the integrated approach required to address the disparate factors that have contributed to ongoing degradation of the Vale. Most importantly, GHD is intimately acquainted with Yellow Creek and the Vale of Avoca since it produced the Geomorphic Systems Master Plan (GSMP) for the ravine that was released in 2025.
Although labelled as a master plan, the GSMP was primarily focused on the impact of ravine hydrology on the channel configuration and water infrastructure. The GSMP study will be a foundation for the more general stabilization and remediation work to come.
GHD’s work on the plan will continue through 2027 and will be directed by the Toronto and Region Conservation Authority (TRCA) with input from the Vale of Avoca Working Group. The Midtown Ravines Group, of which the Deer Park Residents Group is a member, represents the community on this working group through its ten member residents’ associations.
