And interestingly the north side doors at Ricoh were installed about a century before the loop in anticipation of transit service to that spot. At least somebody was thinking ahead.
I worked in LV for a year and I saw more people coming from the streetcar than the GO train at Exhibition station. It's not worth the cost of a GO ticket to travel one station when you can just stay on the TTC.
To be clear, I was not suggesting people were taking the GO to LV....just that the connection between LV and Ricoh and BMO (and the crowds of people they bring) is through the GO station tunnel.
