The following has been taken directly from the bcegg.com website in an attempt to explain what supply management is. There are many differing political views on whether supply management is good thing or a bad thing but it is safe to say that it is a reality and its the perameters we work within.
"Supply management is a unique marketing system whereby farmers grow enough food to match consumer demands and industry needs. Supply management controls domestic produsction and imports. five commodities are supply managed in Canada - eggs, milk, chicken, turkey and broiler hatching eggs."
If you are looking at getting into any of these industries in a big way, look into what is required of you before you start looking for property. As an example when it comes to laying chickens " an egg producer is legally required to obtain a quota from the bc egg marketing board if they have more than 99 layer hens"
