Kate Lyons is a partner at Goodmans. She dedicates her practice to representing both private and public sector clients in municipal and environmental law.

Her expertise includes official plan, zoning and subdivision approvals, in particular in situations where there are disparate public, private and institutional stakeholders.  In the urban setting, she was instrumental in the Yonge Summerhill 20-acre subdivision, the first of its size in Toronto in two decades, the 25-acre Wittington subdivision at Yonge Street and Highway 401 and the 20-acre subdivision at Tradewind and Highway 401. She acted for Tennis Canada in obtaining site plan approval and building permits for its National Tennis Centre at York University.  She acts for SickKids Hospital with respect to their expansion and renovation plans. 

She also has extensive suburban experience and acts for the Town of Oakville in respect of the 7,500 acre area known as “North Oakville”.  As lead counsel for the Town, she successfully obtained a landmark Ontario Municipal Board approval for a community plan which included the preservation of over 1,000 acres of natural heritage land.   A recent article in the Ontario Planning Journal noted that Kate and her partner Rob Howe “marshalled the [3 levels of government] into a formidable negotiating team”.   The Town’s team is described as “the dream team, capable of dealing with everything thrown at it.”

Her experience in Brownfield redevelopment includes involvement with the Goodherham & Worts historic Distillery District in Toronto, the Shipyards redevelopment in Collingwood, Toronto Waterfront Revitalization Corporation, and major Canadian retailers.

Her Brownfield and Greenfield redevelopment experience includes cost sharing agreements, infrastructure financing and environmental approvals associated with infrastructure requirements.

Kate’s environmental expertise extends to providing advice on corporate transactions involving the evaluation and allocation of environmental risks and costs and matters of social licence.  She has acted in numerous transactions in sectors which include mining, natural resources, and manufacturing.

Kate is recognized as a leading lawyer by The Canadian Legal Lexpert Directory for property development and by The Best Lawyers in Canada for real estate. Kate is the former President of the National Club and a former Director of the Textile Museum of Canada.
