I think the benefits of the utilidor for northern communities are that it avoids excavation in the permafrost, and the heat generated by the cables keeps the water and wastewater pipes from freezing. These aren't as relevant here in southern Ontario.
Some electricity transmission circuits in the City of Toronto were direct buried in the ground in the mid 1900s. However, for new transmission line work, in the City, Hydro One has chosen to build a new tunnel and mount insulated cables on the walls. Like this:
They currently have a project to replace two transmission circuits between Esplanade TS and Terauley TS. With the project web site here: https://www.hydroone.com/about/corporate-information/major-projects/power-downtown-toronto
In the mid-town corridor there are 3 circuits, with 9 individual conductors, so there would be 3 groups of 3 conductors instead of the 2 groups shown in the photo.
