Your highest listed choice is considered first when you indicate more than 1 Brock program on your application. If you are not eligible for your first choice, your subsequent choices will be considered in your indicated order of preference. In most cases: If you apply to only 1 Brock program but do not qualify, you will be considered for an alternative or related program. If you apply but are not admitted to a co-op program, you will automatically be considered for the regular, non-co-op program.

What it is	Environmental sciences combines biology, chemistry, economics, and Earth systems to understand how environments work and how human activity affects them. The co-op option lets you alternate between study terms and paid work placements with environmental organizations, government agencies, or companies, giving you real experience alongside your degree. This program suits people who want practical skills in environmental problem-solving and prefer learning through both classroom study and workplace application.	Earth Sciences is a study of rocks, minerals, Earth's structure, and environmental systems — how the planet works and how humans interact with it. The program includes a co-op work placement component, meaning you alternate between classroom study and paid work terms at companies or organizations in geology and environmental fields. It suits students curious about natural systems and interested in learning through hands-on experience in the workplace.	This is a four-year science degree where you specialize in one of many fields — from chemistry and physics to biology, geology, audiology, linguistics, or environmental science. The honours designation means you go deeper into your chosen subject than a general science degree would. The program includes optional co-op work terms, letting you gain paid professional experience alongside your studies, which suits students who want both classroom learning and real workplace practice in their field.	You study the natural systems that support life on Earth — combining biology, chemistry, geology, and geography to understand ecosystems, environmental problems, and how living things interact with their physical surroundings. This pathway is structured to integrate multiple science disciplines rather than focus narrowly on one, and it includes mandatory co-operative work terms where you apply classroom learning to real environmental jobs. It suits students curious about how nature works across scales, from molecules to landscapes, who want hands-on experience before deciding on a specific environmental career.
