Why do small concrete jobs in Ottawa hit a $5,500 minimum?

Small concrete jobs in Ottawa often hit a minimum charge of about $5,500, according to Ottawa price pages, even when the square footage alone would price out lower against the published range of about $9 to $15 per square foot for plain broom-finish work. We found no published breakdown of why: the two Ottawa price pages that mention the minimum state it without explaining it.

Ask each contractor whether a minimum charge applies to your job and what it covers. Since March 1, 2026 the City of Ottawa has also required a hardscaping contractor licence ($319 for 2026) for businesses installing concrete pads, patios, walkways, steps or retaining walls on private property.

Line items to ask about include excavation and base preparation, forming and, where old concrete exists, removal and disposal. The City of Ottawa's Trail Waste Facility charges $144 per tonne for clean concrete without rebar above 250 kg, with a $36 minimum for loads under 250 kg. If the work involves digging, whoever digs is the excavator under the Ontario Underground Infrastructure Notification System Act, 2012, and a locate request must go through Ontario Dig Authority before any ground is broken. That step is free, but it takes at least five business days and has to be arranged before the crew arrives.

A quote at the minimum is not by itself a sign of overpricing; the per-square-foot range tells only part of the story for a small job.

Compare quotes on these lines: the base depth and compacted granular thickness in writing, the specified concrete strength (the 2024 Ontario Building Code sets 32 MPa as the standard for exterior flatwork), the finish and any colour or texture, and whether removal of existing concrete and disposal are included or listed as a separate line.
