Environment & Toxicology program requirements

What the Environment & Toxicology Specialist requires, as the 2026-2027 Arts & Science Calendar states it, and every course it names.

Environment & Toxicology Specialist

  • Science program
  • 14.0 credits
  • Limited enrolment
  • ASSPE0605

Enrolment

This is a limited enrolment program. Students must have completed 4.0 credits and meet the requirements listed below to enroll. The full enrolment requirements are on the Calendar's page for this program.

Completion requirements

(14.0 credits, including 4.0 credits at the 300+level, 1.0 credit of which must be at the 400-level)

First Year: BIO120H1, BIO130H1, (CHM135H1, CHM136H1)/ CHM151Y1, and at least 1.0 credit from MAT130H1, MAT135H1, MAT136H1, MAT148H1, MAT149H1, MAT137Y1, MAT158H1, MAT159H1, MAT157Y1, PHY131H1, PHY132H1, PHY151H1, PHY152H1

Students in this program have the option to enrol in the Arts & Science Internship Program (ASIP) stream.

Second Year: BCH210H1, BIO230H1/ BIO255H1, ENV221H1, ENV222H1, PCL201H1, PSL300H1, PSL301H1 and CHM247H1 (see NOTE 1)

Third and Fourth Years:

BIO220H1, EEB240H1, JGE321H1, CHM210H1, PCL302H1, PCL381H1, PCL382H1, PCL482H1

One of: ENV341H1/ ENV337H1/ EEB320H1 One of: STA220H1/ STA221H1/ STA288H1/ EEB225H1 (see NOTE 2) One of: ENV421Y1/ JPM400Y1/ PCL367H1/ PCL474Y1 (see NOTE 2) At least 1.0 credit from: CHM310H1, EEB321H1, EEB365H1, EEB428H1, ENV441H1, ENV462H1, ESS313H1, JPM300H1, LMP301H1, PCL298H1, PCL386H1, PCL477H1, PCL483H1, PCL484H1, PCL490H1, PCL497H1, PCL498Y1 (see NOTE 4), PHY231H1 (see NOTE 3)

An Integrative, Inquiry-Based Activity Requirement must be satisfied.

The requirement for an integrative, inquiry-based and/or experiential activity must be met by completing at least one of the following: ENV421Y1, JPM400Y1, PCL297H1, PCL298H1, PCL367H1, PCL397Y0, PCL474Y1, PCL497H1, PCL498Y1. Students who complete the Arts & Science Internship Program (ASIP) stream will also meet this requirement.

Notes:

Note 1PSL300H1 and PSL301H1 require MAT 100-level/ PHY 100-level courses.

Note 2PCL201H1, PCL302H1, and PCL367H1 are pre-requisites for students intending to take PCL474Y1. Students intending to take PCL474Y1 must obtain permission from the Undergraduate Student Advisor of the School of the Environment 3 months prior to the intended date of enrolment. Students must also consult with the Department of Pharmacology and Toxicology at least 3 months prior to the intended date of enrolment. Students wishing to take ENV421Y1 are advised to take the course during third year, due to scheduling conflicts with fourth year requirements.

Note 3Students taking PCL477H1 must take BCH210H1 prior. Students taking only PCL367H1 must take 1.5 credits from program electives requirement list of courses to ensure 14.0 program credits. Students may choose to take both PCL367H1 and ENV421Y1/ JPM400Y1/ PCL474Y1 and would then need to take only 0.5 credits from the program electives requirement list of courses to ensure 14.0 program credits.

Note 4Students may not use more than 2.0 credits towards their program from JPM400Y1/ PCL298H1/ PCL474Y1/ PCL497H1/ PCL498Y1.
