About the Client
The client is a regional dairy processor operating a multi-shift production facility in the Mississauga–Brampton corridor. Their plant runs approximately 40,000 units per day across two production shifts plus an overnight sanitation window, supplying institutional and retail buyers across the GTA and into eastern Ontario.
The operation sits under continuous CFIA oversight. The plant's QA team manages a documented HACCP program, a defined allergen matrix, and a tightly choreographed sanitation cycle between production runs. The vendor relationship for sanitation and adjacent property maintenance is treated as part of the regulatory program, not a janitorial line item.
What Was the Operational Problem?
The client inherited an aging sanitation program from a previous vendor. Two consecutive CFIA audits had returned minor findings tied to sanitation documentation gaps and inconsistent allergen cross-contact protocols. Neither finding had escalated to a corrective action, but the cumulative pattern was on the QA director's risk register.
Each finding cascaded into days of audit prep. The operations team was spending two to three days every quarter manually reconstructing checklists from incomplete vendor reports — time that came directly out of production support and improvement work. The plant's QA team had also identified that the previous vendor was missing cycles around shift changes, leaving the plant exposed to microbial cross-contact risk during overnight production runs.
Prior vendors had been generalist commercial cleaners scaled up to food-grade. They followed a calendar, not a production cycle, and their crews rotated frequently enough that institutional knowledge of the plant's allergen segregation routine reset every few months. The QA team had been carrying the cleaning program's accountability rather than receiving it from the vendor.
The trigger for change came when an internal QA review flagged that the plant's allergen segregation cleaning was not being documented at the cycle level. The operations director judged the exposure unacceptable heading into a planned plant expansion that would bring an additional production line online within twelve months.
How Greenbox Designed the Program
Greenbox began with a two-week walkthrough alongside the client's QA and operations leadership. The output was a documented sanitation program built around CFIA-aligned checklists, allergen cross-contact controls, and shift-change handoffs that previously had no defined ownership.
Crews were assigned to specific zones with documented sign-offs at every cycle. The program included scheduled allergen-segregation cleanings tied to the production calendar, not a generic weekly cadence — the cleaning followed the production matrix, the same way an internal sanitation team would. Greenbox crews were trained on the plant's specific allergen matrix and on the supplier's preferred sanitation chemistry before the first paid shift.
All documentation was centralized in a portal the client's QA team could access on demand. Cycle-level sign-offs, chemistry concentration logs, and rework records were generated continuously rather than at audit time. The Greenbox supervisor scheduled a recurring weekly handoff with the plant's QA lead to surface anything before it became an audit risk.
Mid-engagement, the plant brought a new production line online. Greenbox coordinated post-construction cleanup with the construction contractor and the QA team in two passes — rough cleanup at the end of trade work, then a HEPA-level detail before the line entered validation. The new line entered production under the same documented sanitation program already running for the rest of the plant.
Implementation Timeline
- Phase 1
Two-Week Walkthrough
Side-by-side with the client's QA and operations leads. Output: documented zone map, allergen matrix overlay, and shift-change handoff protocol.
- Phase 2
Pilot Cycle
Two-week pilot on a single zone with full documentation, supervisor sign-offs, and a daily QA review. Refined chemistry concentrations against the plant's validated stack.
- Phase 3
Full Program + Portal
Roll-out across the full plant footprint. Documentation surfaces in a shared portal accessible to the QA team. Weekly supervisor handoff cadence established.
What Changed for the Client
Over 24 months, the plant has received zero CFIA findings related to sanitation or documentation — the metric the operations director cared about most. The previous trajectory of minor findings has not recurred under the Greenbox program.
Audit prep, which previously consumed two to three days of the operations team's time per quarter, now takes a few hours. The documentation is generated continuously and lives in a shared portal accessible to the client's QA team, so audit prep has become a review exercise rather than a reconstruction exercise.
Allergen incidents, which had been a slow but persistent issue, dropped to a level the QA team describes as functionally zero across the engagement. The operations team reports that they no longer think about sanitation — which is the outcome the program was designed to deliver.
The mid-engagement plant expansion went live on schedule, with no production downtime attributable to sanitation issues. The new line is now operating under the same documented program as the rest of the plant, and the workflow Greenbox built is the workflow the QA team uses to plan upcoming validations.

Sanitation went from being the thing that kept me up before audits to something I don't think about. That's what I needed from a vendor.
