For sustainability managers and investors, biodiversity is moving from a landscaping detail to a core component of due diligence. Driven by frameworks like the TNFD and evolving GRESB standards, property teams now require specific, location-based metrics. Because nature is context-dependent, these numbers only carry weight when compared to a local city baseline.
We analyzed 704 commercial sites across the Greater Toronto Area to establish these benchmarks, helping you understand where your portfolio stands against the market.
Toronto Benchmarks: Ecological Value
These metrics represent the ecological "health" of the area surrounding a property. Higher values typically indicate stronger habitat support and greater potential for nature-related opportunities.
Data sources: European Space Agency (Natural Cover) and Globio Model (MSA Land Use).
Toronto Benchmarks: Management Complexity
These metrics identify biodiversity sensitivity. While these areas often hold high ecological value, for a real estate professional, higher values indicate a need for more sophisticated management and potential regulatory oversight.
Data sources: WDPA (Protected Areas) and GBIF (Threatened Species).
Defining the Toronto Baseline
Toronto’s geography is defined by its massive ravine systems and high-density urban core. This creates a wide variance in performance:
- Natural Cover: This represents the share of land within 500m of a building that is natural rather than paved. While downtown assets often score below 8%, the city-wide median is 18.7%.
- MSA Land Use: This is a proxy for ecosystem condition. A score of 0.230 is the Toronto average. Assets scoring above 0.346 are situated in environments that are significantly more resilient and ecologically functional.

Understanding Operational Risk & Complexity
High-quality biodiversity data isn't just about high scores: it's about visibility into risk. For certain metrics, higher values indicate that your asset is in a sensitive location that requires active oversight.
Biodiversity Sensitivity Exposure (PASI)
The Protected Area Sensitivity Index (PASI) measures proximity and exposure to environmentally sensitive lands.
- The Benchmark: A typical Toronto asset scores 0.929.
- The Complexity: Assets in the top 10% (scoring > 1.577) are often adjacent to major protected ravines or conservation lands. While this provides great tenant views, it also brings higher scrutiny for any exterior renovations, lighting changes, or site expansions.
Threatened Species Management
Using data from the Global Biodiversity Information Facility (GBIF), we track species classified as at-risk within 1km of a property reported in the last 10 years.
- The Benchmark: The median Toronto building has 5 threatened species reported nearby.
- The Complexity: Properties with 7 or more species represent the highest tier of management complexity in the city. These sites are more likely to be subject to local wildlife protections, requiring specialized oversight during maintenance to avoid legal and reputational setbacks.
How to Use This Data
By splitting these metrics into "Value" and "Complexity," portfolio managers can move from "vague reporting" to "strategic action."
- Identify Nature Leaders: Assets in the top 25% for Natural Cover and MSA are your strongest environmental performers. Highlight these in GRESB submissions and investor reporting.
- Flag Sensitivity Risks: Assets with 7 or more threatened species or high PASI scores should be flagged for "Nature Risk Management." This ensures property teams are aware of the ecological sensitivities before starting capital projects.
- Prioritize Improvements: Assets sitting just below the median are the best candidates for onsite interventions, such as native pollinator gardens or green roofs, to move them into the top-performing quartile.
