|TARA WALTON/TORONTO STAR|
Looking at the maps over the years, there are some consistent patterns. First, we see the familiar check-mark shape of low incomes across Toronto. North-central Scarborough and the Black Creek Drive corridor have concentrations of grow operations year over year.
The 2009 map seems to have more grow operations in the central city, depending how you want to use the term, than in previous years, with clusters in East York and the Kensington Market area. East York had a similar pattern in 2006, but not since. In general, though, the map shows that grow operations concentrate where low incomes meet low densities.
