Mastronardi Produce

Mastronardi Produce Ltd. is described on its own site and in its press archive as a fourth-generation, family-owned business founded by Umberto Mastronardi in the 1940s, with Paul Mastronardi as president and CEO. Corporations Canada's federal registry returned zero results for the corporate name, consistent with an Ontario provincial incorporation rather than a federal one; the Ontario Business Registry itself could not be queried (blocked). Ninety-six news items on the vendor's own site (2019-2026) show Mastronardi acquiring other greenhouses and brands, with no report of outside investment or a change in family control.

SUNSET produce is grown in Mastronardi's own and exclusively-marketed Ontario greenhouses (a November 2024 release alone adds 91 acres in Kingsville and Leamington), a US partner-grower network the company put at over 600 acres and 15 states as of June 2025 (Kentucky, Colorado, Utah, New York, Florida and Rhode Island named in other releases), and Mexican growing or packing operations implied by the company's own employee count and by a Laredo, Texas distribution hub built specifically to receive produce crossing from Mexico. No page gives a Canada/US/Mexico split by volume or season, so the weighting toward what reaches Canadian retail across a year is this scorer's estimate, weighted toward the historic Ontario base with meaningful US and winter-Mexico shares.

• Mastronardi Produce Recognized for Investing in World Class Workforce - SUNSET Grown press “over 3,000 employees in Canada, the US, Mexico, and Holland”

A September 2023 company release states Mastronardi's workforce grew from a handful of employees in Kingsville, Ontario to over 3,000 employees in Canada, the US, Mexico, and Holland. Headquarters and executive leadership (CEO Paul Mastronardi) are in Kingsville; the scale of the US partner-grower and distribution network (over 600 acres across 15 states, plus an E-Verify-registered US employer entity per the careers page) implies a large US workforce share, with Mexico and Holland comparatively minor. The exact country split is not published, so the weighting is this scorer's estimate.

Fresh greenhouse produce has no separate ingredient supply chain distinct from where it is grown, so inputs are treated as mirroring the growing footprint used for the manufacturing factor: Ontario greenhouses as the historic core, a large US partner-grower network, and winter Mexican supply implied by the company's own employee count and its Laredo, Texas hub built to receive Mexican produce. No page breaks out sourcing of growing media, packaging, or energy by country.
