Seems like it might be a bit more nuanced than that. From the article:

There is a federal law, C-3, which deems it an offence for anyone who “intentionally obstructs or interferes with another person’s lawful access to a place at which health services are provided by a health professional.” As far as I saw while I was passing the hospital, the entranceway was clear and no one was stopped from entering or exiting the building. Other than vague mentions, I found no specific evidence that people were prevented from entering or exiting the building.

Update, Feb. 15, 11:06 a.m.: It has come to our attention that the University Ave. entrance to Mount Sinai Hospital closes at 6 p.m. daily. The protest passed by the hospital around 8 p.m., two hours after that entrance had closed. See the bottom of the map below for the University Ave. entrance hours, accessed today from the Mount Sinai Hospital website.

So this may not have broken those laws. There was apparently an incident where the crowd blocked the car of a doctor that was trying to drive home, so perhaps some more care needed to be taken, but I think everyone's just really on edge right now and looking for things to get angry about.
