Several VIA trains were delayed Saturday over fears that a building under construction near Union Station may partially collapse onto the track.

Train 84 from Sarnia was delayed two hours before arriving, and while no trains were cancelled, they were re-routed and large delays were reported.

VIA officials say a building right next to Union Station that is under construction is considered at risk of having a wall collapse onto the track.

There were large lineups reported at VIA counters at Union Station as VIA officials attempted to switch customers onto other trains so they could arrive at their destination on time.

Several trains from Southwest Ontario were stopped for nearly thirty minutes and eventually some reversed, with some passengers telling CityNews they might miss part of the UFC fight in Montreal they were trying to attend.
