Geology Specialist (Science Program) - ASSPE0509

This program gives the deepest level of education within the field of geology, preparing students for careers in the energy and mineral resources sectors, as a government-employed geoscientists, in geoscience research and in many other fields where geoscience knowledge is an asset. The program meets the requirements for gaining membership in the Association of Professional Geoscientist of Ontario (APGO) and similar organizations in other Canadian provinces and territories. The Geology Specialist Program focuses on core geology subjects, such as mineralogy and petrology, sedimentology, structural geology, mineral resources, hydrogeology, Earth history and geologic field mapping. Students are advised to be aware of course prerequisites, check clusters of courses listed for the Geology Specialist program, and consult the Earth Sciences Undergraduate Handbook for logical course progressions. For further questions, please consult with the Student Affairs Coordinator (Scott Moore, Department of Earth Sciences, 22 Ursula Franklin St., Earth Sciences Center, Room 1062 email:

This is an open enrolment program. A student who has completed 4.0 credits may enrol in the program.

(14.0 credits)

Compulsory Foundation Sciences (1.5 credits):

CHM135H1, MAT135H1, PHY131H1

Additional Foundation Sciences (3.0 credits):

Any 3.0 credits from the following, with no more than 1.0 credit from the same category:

Compulsory Foundation Geosciences (3.5 credits):

Additional Foundation Geosciences (2.5 credits):

At least 0.5 credit, but no more than 1.0 credit from each subgroup:

Other Geosciences (3.5 credits):

A minimum of 3.5 credits from the following list that have not been used to fulfill the above requirements. At least 1.0 credit needs to be at the 400 level, and no more than 1.5 credits from the 200 level.


  1. Advanced courses, like CHM151Y1, PHY151H1, MAT137Y1 or MAT157Y1, can be used as credits for both foundation sciences sections, meaning, half of the credit will count for Compulsory Foundation Sciences, and the other half will count for Additional Foundation Sciences.

  2. You may choose more than 2.5 credits from the Additional Foundation Geosciences list. In that case, the additional courses will count towards the Other Geosciences.

  3. You need a minimum of 4.0 credits of 300/400-level courses

  4. Students are advised to check the prerequisites of the upper-year courses when deciding on their 2nd and 3rd-year-course selection.

  5. Students who do not wish to attain APGO certification are advised to speak to the Associate Chair, Undergraduate Affairs concerning their course selection.
