SNOW DAY!!
I just got off the phone with a school operator and it is indeed a snow day...the McMaster website just hasn't been updated yet.
This means school is closed, as well as all services on campus (Compass, DBAC, Union Market, the libraries). If you have a midterm tonite, it is cancelled, as are any intramural sports games.
If you have any questions, call the school if the McMaster website still is not updated.
