Tumber & Associates

What Tumber & Associates does

Tumber & Associates Ltd. is a privately held, owner-operated landscape design and build firm headquartered in Orangeville, Ontario, founded in 1976 and serving high-net-worth residential homeowners across the Greater Toronto Area, Caledon, and surrounding Ontario regions. The company offers an integrated service portfolio that spans custom landscape design, full-scope construction, and ongoing maintenance, supported by specialty offerings such as natural swimming ponds (chemical-free, biologically filtered), custom stonework by certified dry stone wallers, custom ironwork, pools and spas, outdoor kitchens, landscape lighting, and covered outdoor living structures.

The underlying "technology" is artisanal rather than digital: a documented Four Pillars design methodology (Framing, Depth of Field, Enclosure, Journey), 40+ years of accumulated craftsmanship, an in-house team of credentialed trades (master stone masons, certified dry stone wallers, ironwork specialists, carpenters, horticulturalists), and the adjacent Sinovi Masonry subsidiary that internalizes specialty masonry. Project delivery is hand-crafted, custom-quoted, and executed by employed crews under owner Mihal Krnac.

Revenue is generated project-by-project through custom quoting on design-build engagements, supplemented by recurring landscape maintenance contracts. The go-to-market is sales-led via owner-led consultations and word-of-mouth referrals; there are no resellers, distribution partners, or public pricing tiers. Pricing is fully bespoke based on scope, materials, and complexity, with billing structured as multi-year contracts on the maintenance stream. The company is privately held with no disclosed external investors, no funding history, and no public revenue figures.

• Vitaro Landscapes: GTA-area landscape design, construction, and maintenance provider serving residential clients with pools, stonework, and outdoor structures. Overlapping service portfolio and customer base with Tumber in the same metropolitan market.
• Garden Architecture Inc. Toronto-based landscape design and build firm specializing in custom residential gardens and outdoor living environments. Comparable to Tumber in target clientele (affluent urban/suburban homeowners) and design-led project model.
• Landcare: Canadian commercial and residential landscape services firm with national reach, offering design, construction, and maintenance. Comparable service categories though with broader commercial exposure and larger scale than Tumber's boutique model.

Broad incumbents

• Sheridan Nurseries: Established Ontario garden center and landscape services company with retail, design, and installation operations across the GTA. Significantly larger and broader than Tumber, with overlapping landscape design/build services as part of a wider portfolio.

Regional players

Highly comparable in premium positioning and design-led philosophy, but operates on Canada's West Coast rather than in Tumber's Ontario market.
