In Canada "shared-use kitchen" and "commissary kitchen" are used almost interchangeably. Where they pull apart is emphasis: "commissary" leans toward the space as one business’s permitted base, "shared-use" toward the community of tenants scheduled through it. Operationally the difference that matters is not the name but how time, storage and equipment are divided.
Sharing a room does not mean sharing a permit. Nova Scotia publishes the clearest version of this: a permit is not transferable to another person or to another food establishment, and a market vendor who does not own or operate a permitted commercial kitchen submits a Permission to Use a Permitted Eating Establishment form for the kitchen they borrow. That is Nova Scotia’s mechanism and Nova Scotia’s alone — Newfoundland and Labrador’s regulations contain no provision on multiple operators sharing one premises at all, and other provinces have not been verified either way. Ask the authority that issues your permit how it handles it.
The questions that decide whether a shared kitchen will work for you are all about sharing: how many businesses are on the floor at once, whether storage is dry, cold or frozen and whether it locks, which equipment is included versus billed, how allergens are handled between tenants, and what state the room must be left in.
In the United States, The Food Corridor’s shared-kitchen survey reported that 55% of members were women and 47% were minorities, and a USDA study of 179 US food businesses using shared kitchens found 30% had been there one to two years and 26% for three to five, with only 14% staying beyond five years — these spaces are usually a stage, not a destination.
