School cafeteria hood cleaning across Ontario

The Ontario school year runs from the day after Labour Day in early September through the last instructional day in late June, with five professional activity days, a two-week December closure, March Break, and a handful of statutory holidays scattered across the calendar. That gives us a predictable nine-to-ten-week summer window from the final June day to the last week of August, plus roughly twelve scattered weekday closures during the academic year. The summer window is the master scheduling block. We hold capacity for school-board contracts every year from the last week of June through the third week of August and route through cafeterias on a route schedule the board's facilities manager approves in advance.

The PA-day, March Break, and December closure windows are the secondary slots for schools that need a mid-year visit. A high school with a fryer-and-grill cafeteria running on a semi-annual NFPA 96 frequency typically gets a summer cleaning and a March Break cleaning, six months apart. A small elementary school on an annual frequency gets a single summer visit and nothing else. Larger urban high schools with multiple hoods and longer cooking hours sometimes need a third visit, which lands on a December PA-day plus the holiday closure block.

Weekend visits are available for any school where weekday access is restricted. The cleaning is scheduled for Friday evening through Sunday afternoon, the custodial team is briefed in advance, and the kitchen is returned to service-ready state before Monday breakfast prep. Mid-week after-school visits are used for very small cafeterias that can be cleaned in a four-to-six-hour block between final dismissal and the end of the custodial shift.

An elementary school cafeteria that serves a hot lunch four days a week with no fryer, no charbroiler, and no grill operation almost always classifies as low-volume under NFPA 96 Table 11.4. Annual cleaning is the right frequency, and a summer-break visit covers the requirement cleanly. A secondary school cafeteria that adds a fryer, a flat-top griddle, a panini press, and a breakfast service moves into moderate-volume, which is a semi-annual frequency. Some specialty programs — culinary-arts vocational schools, hospitality-and-tourism high school programs, technical institutes with active commercial-kitchen instruction — push into high-volume because the cooking is done for instructional purposes throughout the school day.

Post-secondary dining is a different conversation. A residence dining commons that serves 1,200 to 4,500 meals a day across breakfast, lunch, and dinner is solidly high-volume. So is any campus retail location with a 24-hour menu, any conference and catering kitchen during the summer conference season, and any culinary-arts teaching kitchen at the college or university level. We classify each kitchen on the first visit using cooking-volume hours, equipment mix, and observed grease accumulation, document the classification on the certificate, and confirm the next required service date the same day.

The most efficient way to run NFPA 96 cleaning across a school board is a single master contract that names every cafeteria, kitchen, and warming kitchen in the board, assigns each kitchen a cooking-volume classification, and locks in the cleaning frequency and per-kitchen flat rate for the term of the contract. We hold contracts of this shape with several Ontario boards. A typical agreement runs three years with optional one-year extensions, covers between 12 and 80 sites depending on board size, and is invoiced in equal quarterly installments rather than per-visit so the board's finance team has a predictable cost line.

The board gets a single point of contact for scheduling, a single consolidated invoice format approved by the board's accounts-payable office, and a master compliance binder that aggregates every site certificate into one annual record. Site-specific certificates are also delivered to the cafeteria supervisor or principal so the building-level documentation is complete. When the contract renews, the master binder becomes part of the renewal package and supports the board's risk-management review and the local fire-prevention office's annual inspection cycle. Site lists are reviewed each spring so any school being closed, sold, renovated, or newly opened is reflected in the schedule before the summer cleaning window begins.

Most schools we service get one or two visits per academic year, but a meaningful minority — high schools with a fryer-heavy menu, culinary-arts programs with instructional cooking throughout the school day, and post-secondary residence kitchens that operate seven days a week — need three or four. Those visits land on PA days, on weekends, or in narrow after-school windows. The protocol for an after-school cleaning is straightforward: the cleaning crew arrives 30 minutes after final dismissal once the cafeteria is closed and the custodial team has finished its end-of-day cycle, the crew enters through the service or loading entrance, works behind closed cafeteria doors, and is out of the building before the custodial shift ends or the night-school program begins.

The crew never enters student-area corridors or instructional spaces. A facilities staff member from the board or a custodian from the school is present for the duration of the work. The cleaning is staged so the cafeteria is fully service-ready by the next breakfast or lunch period, including a complete kitchen wipe-down, hood polish, and floor degreasing under the cooking line. A signed compliance certificate is handed to the principal or cafeteria supervisor before the crew leaves, and the photo report follows by email within 24 hours.
