A redesign of this section of Yonge will begin in a few years; and construction will then follow.
The section from Queen to Carlton is set for its do-over in the 2023-2025 timeframe.
The City is currently looking at going North of Carleton to in/around Davenport in the late 2020s
South of Bloor, the design will likely bare a resemblance to the section further south.
Wide sidewalks, trees, decorative paving (likely Yorkville Granite north of Charles).
Pedestrian-only.........probably not.
Pedestrian priority, definitely.
Still under discussion is whether bike lanes will be in the design. But you can be pretty sure that it won't be 4 car lanes in the future.
