Cumulative impacts of aggregate discussions in Trent Lakes


November 03, 2017


On November 9, 2017, Spencer Gilbert-Parkes will be presenting his self-guided research project on the cumulative impacts of aggregate development at the Mining & Aggregate Committee meeting in Trent Lakes.


The Cumulative Impacts of Aggregate Development project included a literature review of the concept of Cumulative Impact Assessment as well as preliminary mapping of existing underlying aggregate resources, natural features and development within Trent Lakes Municipality boundary, culminating with recommendations on further analysis, mapping, and planning strategies that could be implemented to better facilitate sustainable aggregate development in the area.


Spencer graduated with an Honours BSc. from the Ecological Restoration concurrent joint diploma/degree program at Trent University and Fleming College. Spencer undertook an Honours thesis in his fourth year of study, where he worked with Unimin Canada Ltd. at the Nephton site, where he assessed the implications of dust suppressants on biological soil crust development on mine wastes. This research was part of a larger initiative to quantify and provide alternatives to current fugitive dust emission management strategies.


Gilbert-Parkes’ current MSc. research is part of a larger project through the Federal government environmental damages program, which partnered industry proponents Vale SA., Glencore PLC., and Denison Mines Corp., with academic institutions Trent, Guelph and Laurentian Universities. This collaborative effort aims to advance the understanding of Boreal mine biogeochemistry through the focus of reducing environmental impacts of mineral extraction and facilitating mine site closure through remediation techniques. Specifically, Spencer is addressing the geochemical and microbial processes responsible for the immobilization of uranium within treatment wetlands downstream from historic tailings ponds in Elliot Lake, Ontario.


The November 9 presentation will cover:

1. State of Aggregate Resources in Ontario

2. Legislation

3. Associated Impacts and Reclamation Outcomes

4. Cumulative Impact Assessments

5. Preliminary Mapping of Trent Lake Municipality

6. Going-Forward – Mapping, Planning, and Assessment Tool


Spencer was awarded 1st for his honours thesis presentation at the Canadian Land Reclamation Association symposium at Guelph University. He also received the Kawartha Region Conservation Authority Board of Directors Award for his academic excellence and community involvement in advancing resource management within the Kawartha Lakes over the course of his undergraduate degree.
