Amazing. Even if you're not the biggest of the fans. If you are though, spare a good chunk of time to go through all hockey related floors of stuff to see and do. My tip is to get the hop on/hop off tour and her off in front of Sony arena. From there you can get back on the bus or walk to the market(which is closed on Sundays), to Distillery district and to the cathedral which has a great chorus singing during the mass, which is beautiful, even if you're not very religious.
