Last September we were finishing a kitchen in Westboro. The cabinets were installed. The countertop template was done. The plumber was scheduled for Thursday. The homeowner called Wednesday night: she'd decided she wanted a different sink. Could we hold the plumber?
That call cost three weeks. Not because the sink was hard to source. Because the new sink had a different cutout, the countertop fabricator was already booked for the next two cycles, and the plumber's Thursday slot moved to the back of his queue.
Most renovation delays in Ottawa have nothing to do with weather, supply chains, or permit offices. They come from one of seven specific failure points that contractors and homeowners both contribute to. Here's what actually moves a finish date back.
Decision lag is the number one cause
Out of every 10 projects that run late, 7 of them stall on a homeowner decision that hasn't been made. Tile selection. Hardware choice. Paint colour. Light fixture model. The cabinet door style on a single bank of cabinets.
The pattern is always the same. The contractor flags a decision deadline. The homeowner says "I'll get back to you Monday." Monday becomes Friday. Friday becomes the following Wednesday. The trade who was holding a slot for that decision moves to the next job. By the time the homeowner picks, the trade is two weeks out.
This isn't a homeowner-blaming exercise. It's a process problem. A contractor who's run 500 projects knows decisions stall, and they should be building decision deadlines into the contract with named consequences. We use a "decision register" with hard dates. If a decision isn't made by the due date, the project moves to the next available phase and the cost of the delay is itemized.
The fastest projects we run are the ones where every selection is locked before we lift a hammer. Decision drift is the silent killer of every renovation timeline.
Permit timing nobody plans for
The City of Ottawa permit minimum is $117, but the cost is rarely the issue. Time is. A simple bathroom or kitchen permit can clear in 2-3 weeks through MyServiceOttawa. A second-storey addition or a basement legalization under Bill 23 can sit in plan review for 8-14 weeks, sometimes longer if the file gets bounced for missing details.
What homeowners don't realize: most of that time is invisible. The contractor submitted, the city is reviewing, and there's nothing to show until the permit is issued. Three months can pass with the homeowner asking weekly "any update?" and the answer being "still in review."
We build permit time into the schedule explicitly. If your project needs a permit, the calendar starts when the permit lands, not when you sign the contract. A clean Ottawa renovation contract separates "permit phase" from "build phase" with different start dates.
Permit reality check
If a contractor tells you the permit will take "a few weeks" without naming the actual review department or your specific scope, they're guessing. A real number for a side addition in Hintonburg in 2026 is 6-10 weeks. Anyone quoting two weeks hasn't dealt with the current city queue.
Site discovery on older Ottawa homes
Ottawa has a lot of pre-1960 housing stock. The Glebe, Sandy Hill, Centretown, parts of Hintonburg. When you open walls in those homes, you find things the original blueprints never showed.
The classics: knob-and-tube wiring tucked behind plaster. A 60-amp panel that needs upgrading before any new circuits go in. Cast iron drains that crack the moment you move them. Floor framing that was sized for 1925 loads, not a stone island. A foundation crack that only shows up when you pull the basement drywall.
None of these are the contractor's fault. None are the homeowner's fault. They are real conditions that change scope mid-project. A good contractor flags them with a written change order and a revised schedule the same day they're discovered. A bad contractor pushes through, hopes nothing breaks, and the issue surfaces six weeks later as a delay nobody can explain.
The supplier nobody warned you about
Cabinet doors. Custom showers. Specialty lighting. Imported tile. These have lead times that look fine on paper and turn ugly in practice.
A typical Ottawa kitchen project orders cabinet doors at week 6 of the schedule, with a 4-week lead time, expecting them to arrive at week 10. Then the manufacturer emails: production is backed up, expect 6 weeks. Suddenly the install crew that was booked for week 10 has to be rescheduled. Their next opening is week 14.
This is why we run our own in-house cabinet shop. The cabinet door schedule is something we control instead of something we wait on. But even with our own shop, we order critical hardware (hinges, slides, specialty pulls) the day the contract is signed, not the day they're needed.
The lead times that catch homeowners
- Custom cabinet doors: 4-8 weeks, sometimes 12 in summer
- Stone countertops (templated to install): 2-3 weeks after template
- Imported tile: 6-10 weeks if it's coming from Italy or Spain
- Specialty windows (egress, bay, custom shapes): 6-14 weeks
- Custom shower glass: 2-4 weeks after final tile is in
- Light fixtures from boutique suppliers: 4-12 weeks, occasionally never
Trade scheduling collisions
This is the single biggest source of delay on subcontracted projects. The plumber and electrician both need to be in the same wall on the same day. The drywaller can't start until both are done. If either trade slips by two days, the drywaller's slot is gone, and the next opening is a week out.
Multiply this across 8 to 12 trade transitions on a kitchen renovation, and a project that should run 8 weeks runs 12. None of those weeks were anyone's "fault" in isolation. They added up.
The fix is hard scheduling with named workers and a foreman who calls every trade two weeks before their slot, then again three days before. We do this. Most contractors don't, because the time required to manage scheduling at that resolution is significant.
Change orders that aren't priced honestly
A change order should include three things: the cost change, the schedule change, and the trades affected. Most of the change orders I see from other contractors include only the cost.
The homeowner reads "add cost for the wider island." They don't read "and adds 9 days to the project because the cabinet maker has to re-engineer the panel layout, the electrician needs to reroute the island circuit, and the countertop template gets pushed back two slots."
Three change orders into a project, and the timeline has slipped a month. The homeowner blames the contractor. The contractor blames the homeowner for the changes. Both are partly right. The real failure was not pricing the time impact alongside the dollar impact at the moment each change was approved.
Weather Ottawa actually has to plan for
Ottawa winters are a real schedule factor on exterior work. Concrete pours below -10°C need additives or heated enclosures. Roofing in February is risky. Exterior painting from November through April is off the table.
What this means in practice: an addition foundation poured in late October catches the freeze; an addition foundation poured in early November is fighting the weather. We schedule exterior milestones to land before October 15 if possible, and we tell clients straight that any project signed after August 1 with an exterior component is going to wrap in spring, not fall.
Interior work runs year-round, no weather impact. But anyone selling a "12-week winter addition build" in Ottawa is selling a delay they haven't admitted yet.
The honest schedule conversation
Before you sign anything, ask the contractor for a schedule that includes:
- A separate "permit phase" with its own start and end date
- Named lead times for every long-lead item (cabinets, stone, windows, tile)
- A decision register with deadlines for every selection
- Buffer days at trade transitions (1-3 days each)
- Weather contingency on any exterior work
- A change-order policy that prices time alongside money
If the contractor can produce that schedule, your project will probably hit close to its dates. If they can't, the dates on their proposal are aspirational, not actual.
