2020 Annual Natural Homes Tour - Cancelled

The annual natural homes tour which is typically scheduled for the last Sunday in September, will be cancelled this year due concerns around the Covid -19 virus. We hope to return in 2021!

A huge thanks to all the homeowners who voluntarily opened their homes to tour-goers and to all the people who took part in the tour in September of 2019. 

See a CTV news video clip of one of the homes on our 2019 tour.

A Natural Home Tours Thank You

Over the years, many homes and buildings have participated in our Natural Building Annual tour.

Many of the homes that have been featured were models of innovation and energy efficiency and featured living roofs, natural clay wall finishes, rainwater catchment systems, grey water systems, composting toilets, while others incorporated solar and wind electrical systems, high efficiency wood burning appliances, solar domestic hot water systems, as well as a variety of other interesting green technologies.

The Ontario Natural Building Coalition would like to thank all the volunteer homeowners who have over the years graciously opened their doors and welcomed tour-goers. The annual tour would not be possible without them!
