Public concerns over climate change and its associated impacts have significantly increased scrutiny of the Canadian pipeline industry. Pipeline projects proposed in environmentally sensitive areas, such as Enbridge’s Northern Gateway Pipeline and TransCanada’s recently filed Energy East Pipeline, have created concerns for local species and their habitats. These concerns have led to increased regulatory demand, having a significant impact on the cost, schedule, and public perception of proposed pipeline projects in Canada. Despite conducting extensive environmental and socioeconomic impact assessments, and implementing subsequent mitigation measures specifically tailored to species at risk, oil and gas transportation companies continue to face challenges in obtaining regulatory approvals and securing favourable public opinion for proposed pipeline projects. This project will investigate the impacts of species at risk listed under the Canadian Species at Risk Act (SARA) and the Committee on the Status of Endangered Wildlife in Canada’s (COSEWIC) on the (environmental, regulatory, and socio-economic) development of pipeline projects in Canada.
