Hello Lloyd,
Our team says it largely depends on the kind of agroforestry you're interested in. Black Sheep Farm, north of Hanover, is doing some silvopasture work at a small scale.
You could reach out to ALUS Grey-Bruce to inquire about sites they've worked on and landowners who are interested in connecting.
