Annual ONTARIO Natural Building Conference 

Each spring, we host a two day Natural Building Conference and Annual General Meeting at the amazing Camp Kawartha centre, on beautiful Clear Lake near Lakefield Ontario.

Our annual conference takes place over two days and is chock full of amazing presentations! It is great opportunity to learn from leaders in the field and connect with others who are interested in the natural building movement. Each day is packed with presentations, break-out sessions, networking opportunities and great local meals!
