About Horosko Planning Law

Horosko Planning Law was a one-lawyer firm in Toronto that practiced land development and municipal planning law rather than general law. An archived version of the firm's website, last captured in June 2023, described a practice built around the municipal side of the development process: greenfield development, environmental issues, expropriation, urban boundary expansions, employment conversion, cost sharing matters, retail development and intensification projects. The firm's office was a suite at 300 North Queen Street.

The firm's lawyer, Barry A. Horosko, holds a Bachelor of Environmental Studies (B.E.S.) and a Juris Doctor (J.D.), pairing planning training with legal training. Horosko has appeared as counsel before Ontario's Local Planning Appeal Tribunal (the successor to the Ontario Municipal Board) in reported decisions, including cases arising in Vaughan and Toronto in 2019.

Milestones & recognition

  • In a 2019 decision, the Local Planning Appeal Tribunal allowed an appeal brought on behalf of the applicants, permitting a redevelopment of two lots into six residential lots at 23 Rockview Gardens and 10 Southview Drive in Vaughan's Concord neighbourhood, after the City of Vaughan had refused the official plan and zoning by-law amendments needed for the project.
  • In a separate 2019 case management motion in the City of Toronto's Official Plan Amendment 231 proceeding, the tribunal granted a motion brought on a client's behalf, confirming the amendment was in effect on two properties on The Queensway that no longer had any outstanding appeals.
