Douglas F. Jack is as of 2005-03 "presently involved in a Eco-Village development on a 55 acre farm west of Montreal where we are planning to build forty units of housing cluster style at each road serviced end of the property but leaving one third for agro-forestry field farming etc, one third for nature and one third for housing and infrastructure. We include twenty families presently."

The Earthsea eco-village near Lunenburg in Nova Scotia is also considering its future development. It is smaller.

Some nursing homes that pursue the so-called
"Eden Alternative" (http://edenalt.com or http://kallimos.com, work of
Dr. William Thomas support more regular contact between elders and youth, and young children, e.g. putting kindergartens inside the same building as the nursing home, keeping lots of toys around for visiting children, and keeping pets, especially birds and cats, around.

There are now quite good programs for ecological gifts of land that are surrounded by a building development - this is something that is being done in the Bruce Peninsula, among other places. The Nature Conservancy of Canada has pioneered such a process of acquisition and easement. Not sure if any of it applies in Quebec, but I expect so, as federal tax deductions are at least sometimes used.

Beyond Sustainable Trades has more to say on this.
