About the Pearson Accountability Alliance

The Pearson Accountability Alliance exists to provide residents with clear, accessible, and verifiable evidence about how environmental and health policies are applied in communities impacted by Toronto Pearson International Airport. Our mission is pedagogic: to equip citizens with the knowledge, tools, and documentation they need to understand their rights, recognize when those rights are being undermined, and take informed action. By translating complex technical and legal material into plain language, and by maintaining a transparent public record, the Alliance empowers communities to engage confidently with institutions, demand accountability, and advocate for health, safety, and environmental protection grounded in evidence and law.

The Pearson Accountability Alliance (PAA) is a community-led, non-partisan initiative focused on public education, research, and documentation of the health, safety, and environmental impacts associated with Toronto Pearson International Airport. Our work examines the actions and responsibilities of the Greater Toronto Airports Authority (GTAA), NAV CANADA, and all three levels of government, together with their oversight, regulatory, and integrity bodies.

The Pearson Accountability Alliance website is designed as an evidence hub for residents, investigators, lawyers, unions, health professionals, and journalists. Our work is grounded in verifiable evidence: public documents, operational data, formal correspondence, and official records. We are not a complaints portal. We generate, structure, and publish evidence so that when people file grievances, launch investigations, brief the media, or go to court, they are armed with hard data instead of isolated anecdotes.

Public Record & Transparency

One of the Alliance’s core activities is building a public evidence record. This record brings together:

  • Correspondence with public bodies and responsible authorities;
  • Official disclosures and Access to Information materials;
  • Operational, environmental, and health-relevant data; and
  • Documented observations related to noise exposure, safety events, and community impacts.

The goal is to ensure that residents, researchers, journalists, legal professionals, and public officials can see— clearly and chronologically—what questions have been raised, how institutions have responded, and where gaps or inconsistencies remain. Transparency is not an adversarial position; it is a prerequisite for trust, accountability, and effective governance.

Education, Tools, and Accessible Evidence

PAA focuses on education and awareness. We translate technical and legal material into accessible explanations, highlight relevant research and standards, and share tools that help communities understand how aviation operations intersect with:

  • Sleep, cardiovascular health, and chronic disease;
  • Environmental noise and air quality;
  • Land-use planning and infrastructure decisions;
  • Public governance, oversight, and accountability mechanisms.

Wherever possible, the Alliance prefers constructive engagement and solutions—for example, by encouraging better data disclosure, modernized environmental assessments, and the use of up-to-date health guidelines in decision-making.

Accountability as a Public-Interest Goal

Accountability, in PAA’s work, does not mean opposition for its own sake. It means ensuring that:

  • Evidence and risk are accurately represented;
  • Residents’ health and well-being are meaningfully considered;
  • Legal and regulatory frameworks are applied as they are written; and
  • Long-term impacts are not ignored in favour of short-term convenience or growth narratives.

When public-interest issues intersect with health, safety, and environmental protection, prolonged inaction is not neutral. Maintaining a clear, accessible public record is one way communities help ensure that responsibility for decisions is traceable, understandable, and open to review.

The Pearson Accountability Alliance exists to support a simple principle: decisions affecting millions of residents should be informed by sound evidence, guided by law and public-health knowledge, and subject to meaningful public scrutiny. Airports are powerful institutions, and the impacts of their operations are widespread. Communities deserve access to clear information, meaningful oversight, and decisions rooted in public-interest obligations. The Pearson Accountability Alliance exists to help make that possible.
