• Environment

    Some see Toronto Pearson as a wide expanse of runways, terminal buildings, and roadways. However, we also see the open space and creek valleys that make up approximately one-third of our airport’s land. The work of our Environmental Services division has three areas of focus:


  • From the Etobicoke Creek Trail to our honeybees, we take extensive steps to protect the natural resources and wildlife habitats surrounding the airport. Toronto Pearson is committed to ensuring all airport activities are carried out in an environmentally responsible manner, while also meeting the demands of a growing air travel industry.

    Additionally, Toronto Pearson aims to reduce the airport’s impact on surrounding communities and environments, while operating in a safe, secure, and financially sustainable manner, in order to be a good neighbour.

    The goals of our Environmental Services team include:

    • Mitigating environmental impacts of airport operations;
    • Ensuring the environmental compliance of the Greater Toronto Airports Authority's (GTAA) operations and those of Toronto Pearson tenants; and
    • Being a good neighbour.

    Environmental Management System (EMS)

    The GTAA strives to succeed in being a leader in environmental management.

    We use an Environmental Management System (EMS) designed to assist in operating the airport in an environmentally responsible manner, and in compliance with the relevant environmental legislation. Our EMS meets the specifications of the ISO 14001 international standard and is audited annually. In 1999, Toronto Pearson become the first North American Airport to achieve ISO 14001 certification. Through this system, we are able to identify significant environmental aspects, allowing us to set performance targets, ensure environmental compliance, prevention of pollution and continual improvement.

    Environmental Assessments and Compliance

    The GTAA is required to follow the Canadian Environmental Assessment Act (CEAA) for any projects as identified by the act. In doing so, this allows for any possible environmental effects to be identified before the work begins and appropriate mitigation measures or changes to be put in place. This includes both biophysical and socio-economic effects and ensures that we are managing our potential impacts. In 2015 the GTAA reviewed 248 projects under CEAA.

    Emergency Response

    The Environmental Services division plays a key role in responding to environmental emergencies. The GTAA has a documented plan that provides guidance in the event of an environmental incident. Our tenants are also required to have a similar plan. This ensures that should an environmental emergency occur at the airport, any possible impact on environmental receptors are minimized.
