There is a trick that grocery companies use to reduce competition in an area: it's called "Restrictive Covenants" and it's a limitation they can place on a piece of land. It often limits what other tenants on the land can sell, and prevents the landlord from renting to other grocers in a certain radius. These covenants run with the land, which means they can bind all future owners in perpetuity.

I've just published Canada's biggest open dataset for these covenants: https://jacobfilipp.com/covenants/

Next steps: adding more covenants from Edmonton and Halifax. Informing key people that these documents are now available.
