Spring Seminar

Spring Seminar – First-Surface Bird-Friendly Requirements
as per Toronto Green Standard, Version 4

OGMA hosted its first seminar of 2023 on May 18, 2023, at Richmond Hill Country Club. The topic was First-Surface Bird-Friendly Requirements as per Toronto Green Standard, Version 4.

The Toronto Green Standard Version 4 has completely changed the way we can apply bird-friendly markings to glazing. This seminar brought together two influential people who consulted on the Toronto Green Standard, Version 4, and who helped write the CSA standard for bird-friendly design upon which it is based.


Michael Mesure, Executive Director, Fatal Light Awareness Program Canada. A founding member of FLAP Canada, Michael has been with the organization since it began operations in 1993. An author and speaker, Michael regularly delivers presentations on the topic of bird-building collisions, bringing attention to the reflective light issue that impacts over one billion birds across North America every year. His work increasingly focuses on solutions to help mitigate and remediate the challenges of bird migrations in built environments, having led the BirdSafe® Building Standards and risk assessments, to helping develop the Canadian Standards Association’s (CSA) Bird-Friendly Design standard as a technical committee member. Michael tirelessly advocates for bird protections at various levels of government, as well as consults with city planners across North America on developing bird-friendly guidelines and standards.

In addition to his ongoing bird rescue and recovery patrols, Michael’s time is spent partnership-building and enabling collaboration to promote bird conservation programs and other renowned initiatives—including Global Bird Rescue and Bird-Safe Campus—and contributing content to ornithological-focused papers such as Collision Course: The Hazards of Lighted Structures & Windows to Migratory Birds and Window Collisions by Migratory Bird Species: Urban Geographical Patterns and Habitat Associations.
