In addition, for students who are considering a Master's plan of study, ERS offers an Accelerated Master's Program.

ERS requires six items to graduate:

  • Undergraduate Communication Milestone: 60% or higher in ENVS 131: Communication for Environmental Professionals
  • 40 courses total, or 20.0 units
  • ERS core course requirements (8.0 units)
  • 6 ERS / ENVS core electives (6 courses / 3.0 units) where 4 courses / 2.0 units must be labelled ERS. The plan allows for 18 courses / 9 units of 'free' electives of your choice, which can be taken from all disciplines starting in first term. Free electives can be used for specializing your ERS degree.
  • 27 of 40 courses / 13.5 units above 100-level (the plan allows for 13 courses at 100-level)
  • Averages of 65% overall and 70% major

Students in ERS Honours Co-op Plan must also fulfill:

  • 4 successful work term placements
  • 4 Professional Development (PD) courses

Degree 'average requirements' are the same whether you're in the ERS Honours Regular Plan or ERS Honours Co-op Plan. The ERS major average must be 70% and overall (all courses) average must be 65% every term. Averages always must include all courses on record.

Note that ERS core courses are unique to this plan of study and therefore, we will normally not permit core course credit for courses taken at another institution. Students wishing to go on exchange or study elsewhere should plan to stay longer to finish their ERS requirements, or adjust their schedules to ensure they are on campus for core course offerings in the term that they are available. ERS core courses are generally offered once per year in a particular term.

Joint Honours with ERS

Students from other plans wishing to do a joint honours degree with ERS as the second major should refer to the Undergraduate Calendar for the requirements for Joint Honours in ERS.

Undergraduate Communication Milestone

The Undergraduate Communication Milestone is a requirement for all University of Waterloo students. In the Faculty of Environment, a grade of 60% or higher in ENVS 131 fulfills this requirement. If you fail to earn at least 60% in ENVS 131, connect with the academic advisor to discuss options.

To graduate, refer to the Undergraduate Calendar plan requirements from the year you started in ERS.

Important note: ERS core courses are offered once per year in a particular term – refer to the “Course Selection Offerings List for Undergraduate Students” during the course selection period which occurs prior to term enrollment.  

Students can pursue credentials along with their ERS major degree. These can be an option, minor, certificate or diploma. See the Undergraduate Calendar for a comprehensive list of these choices, and their requirements.

More details about credentials for ERS students can be found here: https://uwaterloo.ca/environment-resources-and-sustainability/undergraduate/customize-your-degree

Use the Multi-Plan Template for Credentials (PDF) to ensure you are counting courses for your credentials correctly. A single course can count twice maximum. Once you complete this form, you can send it on the SERS UG Advisor for review.

This page contains supplemental information to that found in the Undergraduate Calendar; specifically, the suggested course sequencing for completing your degree in eight academic terms. Deviating from this sequencing is allowed, but students need to recognize that this may extend the number of terms of study. Students who opt to go on exchange, forcing them to deviate from the suggested course sequence, should take this into consideration when choosing to study abroad and discuss any possible ramifications with their academic advisor.

The Undergraduate Calendar is the official resource for all degree requirements, including undergraduate regulations. Students must refer to the Undergraduate Calendar to ensure approved degree requirements are being met. If there is a discrepancy between this page and the Undergraduate Calendar, the Undergraduate Calendar being the official source for degree requirements and undergraduate regulations, will take precedence.
