I think you're missing a bit of the organization here. Let me see if I can make it clear:
A number of beekeepers in Canada own and manage hives. (Ian is one of those beekeepers). They harvest honey from their hives.
Most commercial beekeepers either bottle and market their honey themselves, or they sell their harvested honey to "packers," businesses that process and bottle ("pack") honey and sell it wholesale.
In this instance, rather than sell to an independent packer (a free-standing business), the Canadian beekeepers organized themselves, invested in the equipment to "pack" honey (the processing and bottling machinery), and hired individuals to do that work. This sort of organization is called a cooperative. The business owned and operated collectively by the members is the packer, in this case. Therefore, BeeMaid is the packer. The beekeepers who own shares in BeeMaid are the honey producers. And HACCP is the set of health and safety standards used to inspect and certify the business packing the honey.
