Grant is one of XCG’s Expert People.  He’s a Partner of XCG based out of the Kitchener, Ontario office and has been helping clients solve environmental issues since 1994.  Grant is a licensed Professional Engineer and designated as a Consulting Engineer in Ontario, as well as recognized as a Qualified Person (QP) in Ontario (as per O. Reg. 153/04 and O. Reg. 406/19, as amended). He is also registered as a Professional Engineer in Alberta and Nova Scotia. In his over 27 years at XCG, Grant has honed his expertise in Site Assessment and Remediation, Groundwater Remediation, Excess Soils Management and Corporate Compliance Auditing -- providing expert environmental consulting services to corporate and municipal clients across Canada.

Grant’s dedication to the environment industry and his integrity have gained him the trust of many clients, regulators, and stakeholders. Grant is involved in the industry which he serves.  He is Past-Chair of the Ontario Environment Industry Association (ONEIA) and has served on the Board of Directors since 2011. He is currently co-Chair of ONEIA’s Excess Soils Advocacy Committee.  His tenacious leadership as member of the Ontario Excess Soils Engagement Group and as a past-Chair of the Canadian Brownfields Network have directly translated into positive government policy outcomes like the “On-Site and Excess Soil Management” regulation under the Ontario Environmental Protection Act.  Grant takes pride in helping to educate and implement the new Excess Soil Regulation across Ontario, wherever possible.

Recognizing a need within Ontario, in 2021 Grant proudly championed the creation of the Qualified Persons Community of Ontario (QPCO) to bring together the common interests of QPs with the regulatory requirements of the Ontario Ministry of Environment, Conservation and Parks.


As a voice for responsible site remediation activities, Grant assists in finding economic benefits to both developers and the local communities they serve. For that work he was awarded the 2015 Brownfielder of the Year by the Canadian Urban Institute. He continues to raise awareness of important environment industry issues through his many speaking engagements and collaboration on advocacy with other associations and businesses to better assist government policy decisions. To acknowledge his leadership, the Ontario Environment Industry Association selected Grant as the recipient of the prestigious 2020 Skip Willis Memorial Award.

Grant is a leading senior environmental engineer with a communications flair. He is as comfortable sharing complex science and project management solutions with Environment Ministers and Policy Advisors as he would be helping solve environmental issues for clients at a social setting. His practical, cooperative approach and unique management experience of client projects makes Grant a valued member of the XCG #ExpertPeople team.
