Agricultural settlement on the boreal forest frontier of Canada has virtually ceased its northward advance. Limited demand for land for new farms is being generated by several Mennonite communities, but acquisition of small units of land by local farmers for enlargement of existing farm operations is characteristic. The demand for raw land exceeds the supply. Potentially arable land is present, but its distribution is discontinuous. Increasingly costly engineering work would be required to prepare much of it for entry, and all but a few tracts lie in areas administered as timber or wildlife reserves.
