All full-time undergraduate students (18 units or more) are members of the McMaster Students Union.  MSU membership gives you access to the MSU Health and Dental plans and allows you to work at one of the 35 businesses and services offered by the MSU.  As an MSU member, you also have the right to run for a position and/or vote in the Student Representative Assembly (SRA) elections, as well as the MSU Presidential election.

The McMaster Students Union is the largest student organization on campus and serves students in two main areas; political representation and the enhancement of student life. We provide political representation and advocate for decisions that are in students’ best interests at the university, municipal, provincial and federal levels. 

The MSU also offers many of the student services that you will use during your time at McMaster. You might get to know us through Welcome Week, visiting the Compass Information Centre, our funding and assistance of more than 350 clubs on campus, or as a major partner in the McMaster University Student Centre (MUSC). You may even come and work for us. The MSU employs more than 350 students each year to run committees, student services and work at our businesses, such as the Union Market convenience store, our restaurant & bar TwelvEighty, as well as Underground Media & Design. We also provide a universal bus pass with the Hamilton Street Railway (HSR) bus pass program. As a member of the McMaster Students Union, you have a student run, multi-million dollar organization at your disposal to help you through the challenges, provide services and protect your interests within and outside the walls of McMaster.
