I went to Ottawa SOI last year and it was two hours travel for me in the pouring rain. However, there was a special direct bus from downtown to Kanata that was available especially for SOI that took some figuring out on my part but it was cheaper than Uber, which would have cost me $40-$50 one way. Exiting from that arena by car can be really scary.
Relying on Uber for hundreds or thousands of people at the end of an event is somewhat of a nightmare…. I do appreciate an event that is close to public transport, so if nationals is in Laval next year, HURRAH! It’s not close to anything that interesting (sorry, Laval) but the metro stop is right in front of the arena, making it way more accessible and a cheap and convenient 20-minute ride from downtown.
On the topic of Landsdowne, that was where nationals 2022 were, but audience was not allowed due to covid. So sounds like that roof is fixed?
