The pla
The plaza is the police station’s property, no that doesn’t mean the public can park there or demand to use it, just like the rest of the property.
looks like there is a freight train derailment near St Catharines, GO trains can’t go there until it’s cleared out. Pictures I’ve seen show quite the amount of damage.
They could run extra streetcars from Exhibition along Queen to West Harbour, or less, but yes the other downtown routes will be able to provide several alternatives.
Yes it could be a challenge, however it would be the first line that parallel streetcars could be run on part of the route, if they wanted to make it work.
