Program details
Overview
Environmental Science at the University of Toronto is an Honours Bachelor of Science program offered at three campuses. Mississauga offers Major, Minor, and Specialist options; Scarborough offers Major and Minor options, along with a Health Sciences Stream variant; and St. George, through the Faculty of Arts & Science, offers Major and Minor options. Scarborough and St. George both include a work-integrated learning option within the program. The subject is described as addressing the environmental challenges facing the world and the relationship between people and the planet. Ontario applicants need an Ontario Secondary School Diploma with six courses at the 4U/M level, including English, Advanced Functions, Biology, and Calculus & Vectors, with Chemistry and Physics recommended depending on campus. The program suits students interested in environmental issues and sustainability who want an Honours science credential, with the choice of a full Specialist stream at Mississauga or Major/Minor options at any of the three campuses, and the option to add practical work-integrated learning experience.
Requirements
Admission Requirements: Offered as an HBSc at all three campuses, this program shares U of T's Ontario baseline: Ontario Secondary School Diploma (OSSD) with six 4U/M courses including English (ENG4U/EAE4U); the co-op component of a Grade 12 course is excluded from admission consideration. Mississauga (OUAC TMW) requires Advanced Functions (MHF4U) and Biology (SBI4U), plus Chemistry or Physics, recommending Calculus & Vectors; Scarborough (OUAC TSP/TXH) requires Advanced Functions, Biology and Calculus & Vectors, recommending Chemistry and Physics; St. George (OUAC TLG) requires Biology, Calculus & Vectors and Chemistry, recommending Physics. International applicants apply through the same OUAC system with the equivalent senior secondary credential and the same subject prerequisites.
