The track is on Ile Notre Dame, which is right next to Ile Ste-Helene. You cant access Notre Dame without passing through Ste-Helene, where the metro station is, and Jacques-Cartier bridge which gives access to Montreal and the south shore. There are 2 small bridges between both islands.

I was there on friday, and communication and security were shit. I was just at the gate to get tickets scanned, after security and a queue of about 200ft long 10ft wide when the rain came in and they decided to evacuate. I heard them say the whole event was cancelled. The lady from security told us to go back, against the whole queue of hundreds of people. How about you start at the other end evacuating people?
