https://www.cineplex.com/VR#s4The new Toronto IMAX VR Centre is now open at Toronto Scotiabank Theatre. I'm not sure if they have any D-Box VR experiences set up but but they have the "Eagle Flight" experience which uses 4 D-Box seats at their Los Angeles location.
Also the Ottawa D-Box VR experience will be opening at the Ottawa Scotiabank Theatre "Soon". Since I live closer to Ottawa, I'll likely check that one out for sure!!
