“When we established the school in 2015, our goal was to develop a new model for continuing professional education that addressed critical skills gaps by connecting industry with the classroom, theory with real-world application and functional expertise with transferable skills,” says Christine Brooks-Cappadocia, assistant vice-president of continuing studies at 첥Ƶ. 

The announcement of these new industry-aligned programs reflects SCS’s commitment to empowering learners and innovating continuing education – and coincides with the school’s 10-year anniversary. This milestone, celebrated at a special event on April 24, marks a decade of growth from its initial offering of two programs to more than 40 professional and language programs, including several first-to-market. 

“We set out to build a school – but we built so much more,” says Brooks-Cappadocia. “What we ended up building was a community with connections that have created remarkable success for our students, instructors, our University and the Canadian labour market.” 

SCS continues to create pathways to meaningful careers by bridging skills gaps and equipping both new graduates and adult learners with practical, in-demand expertise, she says. 

During the April 24 celebration, industry leaders, instructors and academic experts spoke on the school’s role in advancing accessible, future-focused education, reinforcing the significance of the new Fall 2025 programs.

The new programs include: 
  • Students will gain hands-on training in artificial intelligence-powered workflow automation, 3D modelling and building information modelling (BIM), preparing them for high-demand roles such as a construction manager, project coordinator or estimator. This program addresses Canada’s critical need for construction professionals equipped with emerging technologies and project management skills to support productivity and sustainability – particularly in response to the country’s housing challenges.

  • As the school’s first full-time, two-year program, learners will develop practical defensive and offensive cybersecurity skills through hands-on projects that mirror real-world scenarios. Developed in collaboration with industry professionals, this program helps fill the surging demand for cybersecurity experts in Canada’s growing digital economy.
  • Students will gain experience observing live clinical trials while developing critical data analysis skills, preparing them for diverse roles in clinical research. This program strengthens Canada’s leadership in clinical trials and addresses the need for professionals skilled in healthcare data management.
  • Delivered part-time, this program offers practical education in ethical hacking, vulnerability assessment and exploit development. Students will acquire skills that translate directly into the workplace, addressing the rising demand for cybersecurity specialists capable of identifying and mitigating digital security risks.
Expanding the Integrated Year One Program 

The Integrated Year One Program is a model for inclusive academic pathways at 첥Ƶ. Initially launched in partnership with the Faculty of Liberal Arts & Professional Studies (LA&PS), the program allows international students with IELTS (English proficiency) scores between 5.5 and 6.0 (or equivalent) to begin undergraduate studies while advancing their academic English skills. 

Following strong outcomes – measured through improved student performance, higher engagement and increased retention – the program is expanding to include the Faculty of Science and the . 

This growth underscores York’s commitment to reducing barriers to education, ensuring more international students have access to a supportive, integrated entry into their academic journeys, says Brooks-Cappadocia. By aligning language development with degree progress, the Integrated Year One Program sets students up for long-term success in both their studies and future careers. 

The School of Continuing Studies recently marked its 10th anniversary with a celebratory event

“Ten years later, our vision has expanded to address our employer partners’ full range of talent recruitment, retention and renewal goals. The school’s ability to connect the needs of the employer community with educational best practices has the power to transform the Canadian workforce,” says Brooks-Cappadocia. 

The school will continue to evolve, with a focus on becoming a full-cycle solution for organizations ready to build their workforce. Through its growing suite of B2B (business-to-business) solutions, it aims to connect employers with job-ready talent, upskill existing teams and support talent retention. Several new full-time and part-time programs are in development and will be announced later this year.

Thanks to a national grant program, 첥Ƶ’s Faculty of Science has expanded its work-integrated learning (WIL) opportunities and partnerships to undergraduate science co-op and internship students in the new Master of Biotechnology Management program.

The Co-operative Education and Work-Integrated Learning Canada (CEWIL Canada) grant of $115,580 will enhance experiential learning opportunities in science by providing funds to York students and programs. 

About 80 per cent of the grant went directly to domestic students, each receiving a bursary of $1,416. (Only domestic students qualify for CEWIL funding; however, York International matched the grant for international students.)  

In the summer of 2024, Tiffany Pollock, formerly in the Division of Students, now serving as associate director, quality program and development, in the Office of the Vice-Provost, along with Tammy Kim-Newman, associate director of employer and alumni engagement, Career Centre, worked closely with the Faculty of Science, the science co-op team and Markham Campus to win the CEWIL Canada iHub grant in the innovation stream. This grant supports community and industry research and projects through expanding access and career pathways via science-based WIL.  

The grant activity was integrated into two science experiential education courses: COOP 2000 Introductory Professional Communications, a prerequisite for most science co-op students; and BIOT5020 Science Communication and Writing, a mandatory course before students complete a required internship.  

These two courses incorporate WIL by connecting students with 11 industry partners and having teams of students solve problems in the bioeconomy industry, ranging from workplace conflicts to technical project questions. The initiative exposed students to a wide range of careers and industry challenges they may encounter in the workforce.  

This WIL initiative increased employer engagement and career networking for 95 students in the fall term. The instructors of COOP 2000, Kathryn Franklin, course director, and BIOT 5020, Luz Adriana Puentes Jacome, assistant professor, incorporated career discovery and mentorship activities such as a panel discussion, industry networking, a virtual lunch-and-learn career series and industry events such as The Medtech Conference hosted in Toronto last fall.  

“To get them to be able to pursue the best career opportunities possible, they have to first understand where could they work. What are the pathways available to them?” Kim-Newman says.  

The grant also paid for industry training through Canadian Alliance for Skills & Training in Life Sciences (CASTL) which gave students access to globally recognized bioprocessing training and a virtual biomanufacturing facility tour.  

After completing COOP 2000 and BIOT 5020, students have access to the science WIL job board, where students apply on their own and compete with students from other universities.  

Co-op placements can range between eight and 20 months. Some use the time as an opportunity to sample different companies; others apply to the same company repeatedly and could end up with a full-time job upon graduation, Kim-Newman says.  

Students do not receive credits for co-op terms but are paid for their work and gain work experience. The program, which has doubled in enrolment since before the pandemic, now offers co-op opportunities to students in 13 science degree programs, says Mike Scheid, associate dean of students in the Faculty of Science and an associate professor in the Department of Biology. 

The co-op program is now a major draw to York’s Faculty of Science and its goal is to continue building co-op partnerships and develop additional WIL opportunities.  

Kim-Newman agrees that focusing on growing co-op is key to students’ future success.  

“Students’ main objective is to get a good job after they finish their studies,” she says. “We have a responsibility to help provide some open doors. It's up to the students if they go through those doors and continue down the hallway.  

“But,” she continues, “we have an obligation to provide students with some tools and access to career connections and opportunities. And this is what that grant allowed.”

Atmospheric chemists in the Faculty of Science, including Professors Cora Young and Trevor VandenBoer and their graduate student Daniel Persaud, are participating in the 첥Ƶ of Winter Air Pollution in Toronto (SWAPIT), led by Environment and Climate Change Canada (ECCC). The study aims to better understand the mix of pollutants in Toronto’s urban winter air and why known pollutants haven’t declined as expected over the years.

“The unique thing about this study is that it's occurring during the winter months when there are different sources of pollutants from indoor heating to the de-icing of highways, which could have impacts. It is now evident that the levels of some pollutants are elevated in the winter months,” says Persaud. “Most of the other studies focused on smog, which normally occurs during the summer months.”

Media release from April 4, 2024

Ancestral legacy and continued present-day advantages may explain why diurnal frog species kept genes adapted to night vision

Frogs display a remarkable diversity of species as a whole, but does the same hold true for their visual abilities? led by York’s Faculty of Science sought to answer this question by collaborating with researchers in Australia, Belgium, Brazil, Cameroon, Ecuador, Equatorial Guinea, French Guiana, Gabon, Seychelles, Sweden, United Kingdom and the United States, to get a sample of a diverse array of frogs to study the visual pigments found in their eyes.

Ryan Schott
Prof. Ryan Schott

“Through this large international collaborative effort, we were able to study the pigments of frogs from all over the world who have adapted to myriad environments, and for the most part, we found this diversity is ‘reflected’ in the pigments in frogs’ eyes,” says research lead and Assistant Professor in the Department of Biology Ryan Schott.

“We saw this pattern of visual evolution being driven by differences in species that are either aquatic as adults, or that are living on the ground, or trees. On the other hand, we didn’t find much of a difference with the small groups of frogs that have adapted to daytime conditions as opposed to their nocturnal cousins.”

The study, published today in Molecular Biology and Evolution, examined the frog visual system by looking at the visual pigments and other genes in the eyes of a diverse selection of frogs living in vastly different light environments. Visual pigments are the molecules in the photoreceptor cells of the retina that are responsible for detecting light and then sending signals to the brain to perceive that light.

Hoplobatrachus occipitalis
Frogs display a large amount of diversity in their eye pigments, but the study did not find a large difference between nocturnal and diurnal frogs.

“We humans, as well as many animals, have these pigments in our eyes that actually absorb and respond to light,” explains Schott, also with the Centre for Vision Research at York and former research associate with the National Museum of Natural History at the Smithsonian Institution in Washington, D.C. “It's the differences in these pigments that allow us to see at night versus in the day, and allow us to perceive colour differences. So, we were interested in how these pigments have evolved in these frogs in different light environments.”

Schott, who studies the visual system of vertebrates in his lab located at York’s Keele Campus, has previously looked at vision changes of southern leopard frogs as they metamorphose from aquatic tadpoles to frogs living on land, and found a lot of differences. However, the lack of difference between the diurnal and nocturnal frogs came as a surprise. While it is possible that differences were not captured in the method of research, Schott says their evolutionary heritage may provide an alternate explanation.

“Most frogs are nocturnal, and so ancestrally, they really have this visual system that's adapted to these nocturnal environments,” he says. “This is probably suggesting that even the diurnal animals need these adaptations to survive because of course, they could say, get woken up in the night by a predator and then need to use their visual system to escape.”
