Canadian-owned. Privately held.
Since 1979.
47 years ago Frank Zeni opened a 2,000 sq ft tool and die shop in Concord, Ontario. Today the Clover Group is a Canadian tool & die builder, metal stamper, welder and sub-assembly manufacturer. 208,600 sq ft of connected production across multiple Ontario locations, 300+ people, and 48 million parts and sub-assemblies shipped each year.
We stayed family-led on purpose. Decisions are driven by customer satisfaction rather than shareholder pressure, and the tool room still runs the way Frank set it up.
Six letters. Six promises.

The people accountable for it all.
Clover is run by a tight team: President, VP, General Manager, and a department-head layer covering Sales & Engineering, Production, Quality, Tool Room, Materials, Maintenance, HR and IT. Senior leadership sits with customers on any program that needs it. For a full introduction or a site visit, get in touch.
"We’d rather win your program by being straight about timing than win it on a number we can’t hit. Long programs are built on trust."
"Build tools that last. Build parts that run. Build people who stay."
We show up in our neighbourhoods.
- Annual community park cleanups near every Clover facility.
- Over $500,000 raised for children's hospitals through in-house charity events.
- Tree planting and pollinator gardens on company property alongside local volunteers.
- 99% of our shop waste is recycled. Goal: carbon-neutral operations within 10 years.
Let’s build what’s next — together.
