Sustainability Catalyst Internships
The Sustainability Catalyst Internships offer U of T graduate students paid opportunities to work with partners on real-world sustainability solutions across the Greater Toronto Area, while receiving additional support from university staff.
The internships are part-time and run during the summer period each year from May to September. The internships are managed by the secretariat of the President’s Advisory Committee on the Environment, Climate Change, and Sustainability (CECCS).

Applications for partners open in February and students are awarded internships in March.
