Stay at home, and watch movies, play games, or something.
Go for a nice, long walk.
Sleep because you won't get another chance to do so until Canada Day.
If you have a hobby, work on it; if you don't, try to find one,
like drawing nature scenes.
Do your assignments, and take your time: most people will be busy
not doing it, and stressing out later; you can use the fact that it
will be quiet to reduce your distractions and actually be
productive.
Most importantly, do not try to go away to your cottage, or
back home (if it's out of town): the traffic will be horrendous.
