A new hybrid option will be brought to Council this Fall that is different than the contentious proposal that barely made it through a divided City Council. It's going to be a lot closer to the original hybrid option that runs along the rail corridor, freeing up the land around the Keating Channel for Waterfront Toronto redevelopment. It's a good compromise if we have to retain the Gardiner at all.
While I'd much rather prefer we remove the Gardiner, I'm optimistic that we can make it work with it up. Downtown — particularly around South Core — condos and office towers are hemming in the Gardiner and rail corridor. Bridges running alongside the rail corridor connecting buildings have successfully concealed the railway and made the area around it feel urban. We can do the same along the Gardiner, creating a sort of above ground PATH like Calgary's +15 skywalk network. The Gardiner would be hiding behind.
The remaining challenge is making the pedestrian crossings less gloomy and intimidating. That can be accomplished by landscaping right up to the expressway with trees and welcoming outdoor spaces, making the crossing much shorter. Lighting those spaces under the Gardiner with interesting ceilings and pillars where pedestrians cross, would round out the pedestrian friendly measures.
Since we're not going to build a tunnel into the ground, I'd be content to turning the existing elevated Gardiner and Lakeshore running under it into a "tunnel" of sorts with buildings on either side.
