Maybe take a look at buying on the Queen Charlottes (Haida Gwaii). Property is relatively cheap. Government is very local. I am living in Masset and enquired of our mayor if there was any bylaw against or regarding wind turbines on my property (which is in town). He said no problem.
Outside of towns there is a Skeena Regional Management District. Lots of people do many innovative things on their properties. However most do have septic. Our local Coop has been selling composting toilets for the past few years though.
email@example.com Any help I can be.
