This morning the Globe and Mail published an article by Toronto’s chief planner, Jennifer Keesmaat, called Greenbelts make cities more livable, affordable and transit-friendly.
The headline immediately caught my attention because conventional economic wisdom would suggest that supply constraints – whether natural or artificially created – generally have a negative effect on housing affordability.
To be clear though, I support Ontario’s greenbelt. I think an urban growth boundary is the right thing to have if we want to build sustainable, walkable, and transit-oriented communities. But I’m also not blind to some of the potential (negative) externalities.
However, Keesmaat’s article got me wondering just how prevalent those externalities might be and to what extent our greenbelt is actually impacting housing affordability in Toronto. In her article she cites a recent report by the Pembina Institute that very clearly argues the following:
“There is no shortage of land throughout the GTA [Greater Toronto Area] to build single-family homes for decades to come, but this land is predominantly located far from the City of Toronto and other established centres of employment in the GTA.”
