City buildings to get bird-friendly retrofits

Summary#

This item is about reducing bird deaths from window strikes at City-owned buildings in Toronto. It directs City staff to finish bird-friendly retrofits at Metro Hall, add more protections at Metro Hall and City Hall this spring, and assess and retrofit other City buildings that pose high risk to birds. The goal is to make City properties meet bird-safety standards the City promotes and to cut collisions during migration seasons.

• Main change: Finish treating Metro Hall’s windows and glass railings up to at least the fifth floor (about 16 metres) as soon as possible.
• Add “suitable mitigation measures” at Metro Hall and City Hall this spring (for example, window film, glass markers, or lighting changes during migration).
• Do a risk assessment across other City-owned buildings to find the greatest bird-collision risks.
• Create and carry out a plan to retrofit remaining City buildings, starting with the highest-risk facades.
• Timing: Metro Hall retrofits are urgent; seasonal measures begin this spring.
• What is unclear: No budget, firm timelines, or detailed technical standards are stated in the material provided.

What it means for you#

• City staff and visitors at Metro Hall and City Hall

  • You may see work crews installing window film or glass markers, mainly up to the fifth floor.
  • There could be short-term noise or access limits during installation.
  • Windows and railings may look different (patterns or markers) after retrofits.

• People who live, work, or pass near these buildings

  • This could mean fewer dead or injured birds found around Metro Hall and City Hall, especially in spring and fall migration.

• City departments and contractors

  • Corporate Real Estate Management must schedule and manage retrofits and a portfolio-wide risk assessment.
  • Contractors who supply and install bird-friendly treatments may see new work.

• Taxpayers

  • The City will likely spend money to assess buildings and install treatments. No cost estimate is provided.

• Private building owners and tenants

  • This item does not change rules for private buildings. It applies only to City-owned buildings.

Expenses#

No publicly available information.

• The actions likely require capital spending to buy and install window film or bird-friendly glass on City buildings.
• Staff time and possibly outside expertise will be needed for the risk assessment and plan.
• There may be seasonal costs for short-term measures during migration (for example, lighting adjustments or temporary markings).
• Ongoing maintenance may be needed to keep treatments effective and clean.

Proponents' View#

• The item appears intended to cut bird deaths from window collisions at City-owned buildings, focusing first where risk is highest (below about 16 metres and at known hotspots).
• Finishing Metro Hall’s retrofit could deliver quick safety gains at a site with a history of bird strikes.
• Adding measures this spring targets peak migration periods, when most collisions occur.
• A risk assessment and a prioritized plan can direct funds to the most dangerous facades first, improving impact and efficiency.
• The background notes say bird-friendly glass or window film can reduce collisions by up to 95%, suggesting these measures are effective.
• The City would bring its own buildings in line with its bird-friendly standards used for new developments, showing leadership.

Opponents' View#

• One concern is cost. The item does not state how much the retrofits and assessments will cost or how they will be funded alongside other City priorities.
• “As soon as possible” and “suitable mitigation” are not defined. This may lead to uneven action or delays if priorities or standards are unclear.
• Installation work may disrupt building operations and public access in the short term.
• Treatments may change the look of glass surfaces, which some users may see as a trade-off.
• The plan covers only City-owned buildings. Most collisions happen across the wider city, so the broader problem would remain outside this item’s scope.
