Landscaping in Ontario

Sometimes — but contractors mark up materials partly to warranty them, so supplying your own paving usually voids the guarantee on the surface (though not the workmanship). Plants are the better DIY-supply candidate if you can source quality stock. Discuss it at quote stage; springing owner-supplied materials on a contractor mid-project causes friction and disclaimers.

One mobilisation is cheaper per unit of work — machinery hire, waste logistics, and crew setup get amortised. But phasing spreads cash and lets you live with the garden before committing to later stages. If you phase: do groundworks, drainage, and irrigation conduits first, even for areas finished later. Retro-digging finished areas is the expensive mistake.

Insist every quote itemises: site prep and excavation, materials by type and grade, labour, waste disposal, and planting with plant sizes specified. The classic trap is comparing a quote with 100mm compacted sub-base against one with paving laid on sand — same look for a year, then one fails. Cheapest itemised quote beats cheapest total.

The first year decides whether planting establishes: regular deep watering (especially trees and hedging), mulch top-ups, formative pruning, and quick replacement of failures. Many landscapers offer a 12-month establishment package or plant warranty conditional on documented watering. Budget 5-10% of project cost for year-one care, or the planting investment erodes.

The usual surprises: waste disposal (excavated soil is heavy and expensive to dump), poor access surcharges, drainage problems discovered mid-dig, tree roots, buried services, and irrigation added late. A contractor who surveys properly and asks about underground services before quoting is protecting you from mid-project extras.

For a single element — new lawn, one patio, a border — a good landscaper designs as they quote. For a full garden rework, a designer's plan (a few hundred to a few thousand, depending on market) pays for itself: contractors quote against the same drawing so bids are comparable, and sequencing mistakes (irrigation after paving, for example) get designed out.

Canadian project costs track US figures roughly at par in local currency: typical projects CAD $2,000-$15,000, full backyard builds $15,000-$60,000, hardscape at $15-$35/sq ft installed. The short season concentrates demand — winter-quoted projects often price 10-15% better than mid-summer bookings.

Freeze-thaw is the design constraint: paver bases need 8-12 inches of compacted granular (versus 4-6 in mild climates), structural footings must reach below frost line (1.2-1.8m in much of the country), and drainage must handle spring melt. This adds 20-40% to hardscape costs versus mild-climate equivalents — a cheap quote usually means a shallow base that heaves by year three.
