This morning I spoke to the Globe and Mail about the evolving nature of Dupont Street here in Toronto. The impetus for the discussion was this: Dupont Street is now seeing a lot of residential intensification, but the street itself remains a bit of a crosstown highway. It's not yet a "complete street." And since Junction House is effectively on the west end of this midtown artery, John Lorinc asked to get my thoughts.

The point I tried to make is that, in my opinion, this is first and foremost a zoning issue. Dupont Street is seeing intensification, but it is largely happening on the north side of the street, abutting the rail corridor (purple and red in the above Official Plan map). The south side of the street is, for the most part, a low-rise neighborhood (yellow in the above map).

This kind of edge condition is somewhat unique in the city: low-rise on one side of the street; higher density housing, retail, and office on the other. But it is particularly problematic if you're trying to create a great main street, because single-sided retail streets generally don't work very well.

We could certainly have a discussion about sidewalk widths, bike lanes, and other streetscape improvements; but in my mind, there is nothing inherently bad about the cross section of this street. The right-of-way width is 20 meters, meaning there are generally two lanes going in each direction. This is a dimension you'll find all over the city, including on beloved streets like Queen Street.

The problem here is what is abutting the street, and it is something that is systemic across the city: we have too many arterial roads that only allow for low-rise housing. So if you were to ask me what to do next, and I was asked this morning, the first thing I would do is up-zone the south side of Dupont and allow for non-residential uses at grade.

And once this is done, I am certain it will snowball many other positive improvements.
