well the local field way out here in boondock land gets charged about $15/day/person from his insurance company, and thats before he has to fiqure out employee costs, taxes, improvements and the all important profit. And one little incident and that all can go bye bye, so hence the reason some fields are super strict about what you can or can not do.
I'd imaging costs would be higher out in Ontario.
So unless you have a couple hundred acres of land that you already own and are looking to do something other then raising piglets and cows with the odd chicken or two running around. It's best to just go to established fields.
