What type of zoning needed to sell produce in NS/NB

Hello out there,

I was just curious , because im doing some research from the west coast about the east .. and am lacking information. If i were looking to purchase land in Nova Scotia or New Brunswick with the intention of starting some sort of small scale market/ CSA business what sort of zoning should i be looking for ? I know what im looking for in regards to acreage , proximity , ect ect , but is there a particular zone regulation that has to be followed to produce food to sell? Sorry this is probably such a basic question , but i just dont have any farmer friends in the area to ask & google has given me no help!

thannnkkk youuuuu
