The College of Computational, Mathematical, and Physical Sciences (CCMPS) (formerly the College of Engineering and Physical Sciences), is one of eight faculties – referred to as “colleges”^[1] – at the University of Guelph in Ontario, Canada. CCMPS operates on the University of Guelph main campus, one of four across Ontario, and has one of the largest faculty, staff, and student populations of the seven colleges at U of G.

CCMPS offers undergraduate degrees, master's and PhD graduate programs spanning disciplines in: Bioinformatics, Biophysics, Chemistry, Computational Sciences, Computer Science, Cybersecurity and Threat Intelligence, Data Science, Mathematics and Statistics, Physics, and Toxicology. The current dean is interim dean Dr. Stacey Scott.^[2][3]

The Province of Ontario purchased 200 hectares (490 acres) of farmland and opened the Ontario School of Agriculture, May 1, 1874, which later became Ontario Agricultural College (OAC).^[4] The Macdonald Institute and Ontario Veterinary College (OVC) were created in 1903 and 1922, respectively, and in 1964, the three bodies merged to form a single institution: the University of Guelph.

While CEPS did not exist in its current form at the time, its subject areas were taught across the university. For example, Engineering had been taught within OAC in various formats since its establishment in 1874. In 1957, the Department of Agricultural Engineering changed its name to the Department of Engineering Science. In 1965, the Senate of the University of Guelph established The School of Agricultural Engineering further adding the B.Sc.(Eng) degree.^[5] In 1969, Wellington College was divided into the College of Arts, the College of Physical Science, and the College of Social Science.^[4]

In 1989, OAC's School of Engineering merged with the College of Physical Sciences to form the College of Physical and Engineering Sciences. In 2008, the University of Guelph launched Canada's first full-fledged Nanoscience major within CEPS. In 2017, the college's name was changed to the “College of Engineering and Physical Sciences."^[6]

The Physical Science and Engineering Education Centre (PSEER) was established in 2012 within the College of Physical and Engineering Sciences to support teaching and learning in Chemistry, Physics, Mathematics and Statistics, Computer Science, and Engineering. The centre provided funding, events, and resources to advance science and engineering education and research on teaching practices.

In late 2018, the University of Guelph established the Centre for Advancing Ethical and Responsible Artificial Intelligence (CARE-AI).^[7] One of just a few groups of its kind, the research and teaching centre aims to improve life through artificial intelligence and address ethics in AI.

In June 2025, the University of Guelph’s Senate voted to dissolve the College of Engineering, and Physical Sciences and its associated School of Engineering, effective July 1, and create two new colleges: College of Computational, Mathematical and Physical Sciences, and College of Engineering. This was the first time in nearly 20 years that a new faculty had been created at the University of Guelph.

The College is one of eight at the University of Guelph and focuses on research and teaching in fundamental and applied sciences. It offers undergraduate and graduate programs that include opportunities for experiential learning. The College conducts research across a range of scientific disciplines and maintains partnerships with external organizations.^{[citation needed]}

Today, the college is home to three departments and one school. Its key priorities are grounded in research and education. Its about page state that “alongside our stakeholders and other U of G Colleges, our exceptional community is relentless in its pursuit to solve some of the world’s most complex problems.”^{[citation needed]}

Following the decision to dissolve CEPS and establish two new colleges, the College of Engineering was created^[8] The College is dedicated to engineering education and research in areas such as water and environmental engineering, sustainable energy systems, instrumentation design, resource and waste management, intelligent systems and automation, food and bioprocess engineering, and more. Located in the Albert A. Thornborough Building, the College is home to four departments:

• Civil, Environmental, and Water Resources Engineering
