Catering a conference for 50 to 500 people is mostly a project-management problem wearing a chef's apron. Get the timeline right and the food takes care of itself. Here is the stage-by-stage checklist that keeps large-scale catering calm, on budget, and genuinely good.
8 Weeks Before: Lock the Format
The single biggest decision you will make is format, and it cascades into everything else — budget, staffing, venue layout, timing. You have three broad choices. Drop-off means individually portioned meals delivered and left for you to distribute; it is cheapest and lowest-touch but struggles with hot food at scale. Buffet means food set up on serving lines that guests move through; it is the workhorse of large events. Staffed service means the caterer brings people to carve, replenish, and manage the line; it costs more but transforms the experience.
For anything over 50 people, buffet almost always wins. It keeps food hot across a long service window, scales without ballooning per-head cost, and creates the visual abundance that makes a room feel well-fed rather than rationed. Drop-off works for smaller breakout sessions; full staffed service makes sense for VIP dinners or client-facing showcases. Decide this first, because every later step assumes you already have. Lock it eight weeks out and resist the urge to change it — late format changes are where conference catering budgets and tempers come apart.
6 Weeks Before: Set the Budget
With format chosen, you can set a realistic per-head budget. In Toronto, plan on roughly $15 to $30 per person depending on format and ambition. Drop-off and simple buffets sit at the lower end; staffed service and premium menus push toward the top. Multiply by your expected headcount, then add a sensible contingency — conferences almost always feed a few more than the RSVP suggests.
What drives the number up: hot food over cold, staffed service over self-serve, premium proteins, individual packaging, and any equipment the venue cannot supply. What pulls it down: booking early, choosing a focused menu rather than an endless spread, accepting a standard format, and using a caterer whose kitchen is close to your venue. Watch for the hidden costs that do not appear in the headline per-head figure — delivery minimums, setup and teardown fees, equipment hire, and gratuity on staffed events. A quote of "$18 a head" can quietly become $24 once those land. Ask for the all-in number in writing now, so your budget reflects reality rather than the brochure.
4 Weeks Before: Confirm Dietary Requirements
Four weeks out, survey your attendees. A short form attached to the RSVP works best: ask people to flag vegetarian, vegan, halal, kosher, gluten-free, and any allergies, with a free-text box for anything unusual. Keep it simple, because every extra field lowers your response rate. Aim to have your data back two weeks before the event so the caterer can plan properly.
Once the responses are in, translate them into hard requirements for the caterer. As a minimum for any large conference, you should cover vegetarian and vegan options, a gluten-free path, and halal where your attendee mix warrants it. Do not treat these as token single dishes tucked at the end of the line — plan enough volume that someone arriving late still has real choice. Allergen information must travel all the way to the serving table, ideally on clear labels at each dish, so guests can make safe decisions without interrogating staff. Share the final dietary breakdown with your caterer in writing and confirm they can meet it. If a caterer is vague or dismissive about dietary needs at this stage, treat it as a serious red flag.
3 Weeks Before: Book and Brief the Caterer
By now you should be confirming, not shopping. Send the caterer a complete brief: final-ish headcount, event date and timings, venue address with access notes, your chosen format, the full dietary breakdown, and your budget. The more precise the brief, the more accurate and accountable the response.
Get the important things in writing — the menu, the all-in price, the service window, what equipment they bring versus what you must provide, setup and teardown times, and the cancellation and final-numbers policy. A good caterer will come back with clear answers, sensible questions, and a written confirmation. Be alert to red flags in their responses: reluctance to commit to a fixed price, fuzziness about dietary capability, no questions about your venue or access, or pressure to decide instantly. Ask too about their contingency plan — what happens if numbers jump at the last minute, or if a piece of equipment fails on the day — because a caterer who has an answer ready has done this before. Reliability at this stage predicts reliability on the day. If you are catering a conference in Toronto or across the GTA and want a caterer who answers these questions cleanly, that clarity is exactly what you should be testing for now.
1 Week Before: Logistics and Setup
The final week is pure logistics. Confirm venue access in detail: what time the caterer can arrive, where they load in, whether there is a service lift, how far the kitchen or staging area is from where guests will eat, and whether power and water are available if needed. Walk the route mentally from the loading dock to the serving line, because that path determines how smoothly setup runs.
Confirm setup time — a buffet for hundreds needs a meaningful window before doors open, not ten frantic minutes. Check serving equipment: chafing dishes, carving stations, utensils, plates, and napkins, and agree explicitly who is supplying each item. This is where The Carvery's format earns its place in a conference environment: a carving station is largely self-contained, sets up quickly, holds food hot across a long service window, and creates a focal point that paces the line naturally. Fewer moving parts means fewer failure points.
Confirm the serving layout with the venue so the line flows without bottlenecks — for large numbers, a double-sided line or several stations move people through far faster than a single queue, and the difference shows up directly in how long your guests stand waiting. Make sure someone on your side knows exactly when and where the caterer is arriving, and give the caterer a single named contact rather than a committee, so questions on the day get answered fast. Confirm headcount one final time and pass any last dietary additions across in writing. A calm setup is an invisible one: by the time guests walk in, the food should simply be there, hot and ready, with no sign of the logistics that got it there.
Day Of: What to Monitor
On the day, your job is to watch the few things that actually go wrong. Monitor service pace first: if a single line is backing up, open a second serving point or split the queue before frustration builds. Keep an eye on dietary queries — make sure labelled dishes stay labelled as they are replenished, and that staff can answer allergen questions confidently.
Track replenishment timing so popular dishes never sit empty while the rest of the line waits; a good staffed service handles this automatically, but it is worth a glance. Keep an eye on temperature too — hot food should stay genuinely hot across the whole service window, and a carving or chafing setup is built to do exactly that. Finally, watch waste and flow at the back end: clear used plates promptly so the room stays pleasant, and note roughly how much food is going untouched so you can adjust quantities next time. You are not running the kitchen — you are the calm point of contact who spots a problem early and gives the caterer the nod to fix it. Most conference catering issues are small and solvable if someone is paying attention in the first twenty minutes of service, which is also when the longest queues form, so that is where your attention is best spent.
After the Conference: What to Capture
The event is not over until you have captured what you learned. Gather quick feedback while it is fresh — a one-line question to a few attendees and your own team tells you more than a formal survey weeks later. Take photos of the setup and the food at its best; you will want them for next year's planning and for internal sign-off.
File the invoice and check it against the written quote, flagging any surprises so they do not recur. Most importantly, write down what you would do differently: quantities that ran short or long, timing that slipped, a format that did or did not suit the room. Note which dishes emptied first and which barely moved — that single observation sharpens your ordering more than any other piece of feedback. Conference catering improves enormously the second time you work with the same caterer and your own notes, because the guesswork drops away and both sides already know what good looks like. Capture it now, while the details are sharp, and keep the notes somewhere your next event's planner will actually find them.
The Checklist at a Glance
Here is the whole thing condensed, for the planner who just wants the list:
- 8 weeks: Lock the format — buffet wins for 50+ people.
- 6 weeks: Set a per-head budget ($15–$30 in Toronto) and get the all-in figure in writing.
- 4 weeks: Survey dietary needs; cover vegetarian, vegan, gluten-free and halal as a minimum.
- 3 weeks: Book and brief the caterer; confirm menu, price, equipment and timings in writing.
- 1 week: Nail down venue access, setup time and serving equipment ownership.
- Day of: Monitor service pace, dietary labelling, replenishment and flow.
- After: Capture feedback, photos, the reconciled invoice, and notes for next time.
Follow the timeline and feeding hundreds of people stops being stressful and starts being routine. The whole system rests on one idea: decide early, confirm in writing, and leave nothing important to the day itself. If you are planning a conference across Toronto or the GTA and want a caterer who handles scale calmly — and who can answer every question on this checklist before you ask it — request a quote and we will walk the checklist with you.
