A backyard transformation in Ontario rarely involves just one element. Use this calculator to budget the full project: patio, wall, planting and any add-ons that matter to you. Real ranges from a working Hamilton-area crew.

How to use this
Three useful patterns:
Start with what is non-negotiable. Set the patio size and paver grade first because for most homeowners the patio is the centrepiece. Then layer in retaining walls (if you have grade), then planting, then add-ons.
Phase the project. If the total is higher than your budget, the calculator helps you see what to defer. Hardscape (patio, walls) almost always goes first; lighting, irrigation and pergolas can be added in later seasons.
Compare scenarios. Try a 25 m² patio with mid-grade pavers vs a 35 m² patio with economy pavers. The total may be similar but the long-term feel of the yard is very different.
What this calculator does not include
- Pool installation. Pool building is its own project category, typically $50,000 to $150,000 separately from the surrounding landscape. See our pool building service.
- Deck construction. If your yard needs a deck rather than a patio (typically because of grade), read our deck vs patio comparison and add $350-$600 per m² for composite decking.
- HST. All numbers are pre-tax. Ontario HST (13%) applies to residential landscape work.
- Site-specific surprises. Heavily compacted clay, buried debris, unusual access constraints can all add cost that no calculator can anticipate.
Frequently asked questions
How accurate is the total budget estimate?
Within roughly 15 to 20% for a typical Ontario residential backyard. The most common reason a real quote falls above the range is a site condition surprise (drainage worse than expected, soil softer than expected, access harder than expected).
Should I phase the project to spread the budget?
Often, yes. Hardscape (patio, walls, drainage) almost always goes first because changing them later requires demolition. Planting, lighting and pergolas can be added in subsequent seasons without disturbing the hardscape.
What is the most common backyard budget bracket?
Most full-backyard transformations in the Hamilton, Halton and Niagara regions land in the $25,000 to $60,000 bracket. Below that is usually a focused single-element project; above that includes premium materials, multiple outdoor rooms or estate-scale work.
Can I get a printed copy of my estimate?
Not from this page directly. Take a screenshot or note the result. When you book a free on-site quote, the calculator output is a great starting point for the conversation.
Does this calculator work for Halton and Niagara projects, or just Hamilton?
All three regions. Costs are reasonably consistent across our service area. Oakville and parts of Burlington tend slightly higher because of larger lots and premium material expectations; St Catharines and rural Halton Hills tend slightly lower or comparable.
