The number one question GTA homeowners ask — and the one contractors answer most optimistically. Here are honest timelines for every major project type, the phases nobody budgets time for, and how to actually keep a renovation on schedule.
"How long will it take?" is the first question every homeowner asks, and it is the question most likely to get an optimistic answer. Contractors quote construction time; homeowners hear total time. The gap between those two numbers — design, permits, material ordering, and the inevitable surprises inside older GTA walls — is where most renovation frustration lives.
This guide gives you realistic, honest timelines for the most common renovation projects in Toronto, North York, Etobicoke, Mississauga, and across the GTA, based on how projects actually unfold in 2026 — plus the specific reasons projects run late and what you can do to keep yours on track.
These ranges reflect on-site construction time for a well-planned project with a competent crew. Add the pre-construction phases discussed below for total calendar time from decision to completion:
Construction is often less than half the total calendar. A realistic project moves through five phases. Design and planning comes first: even a straightforward kitchen needs 2–6 weeks of decisions — layout, cabinets, finishes, fixtures — and larger projects with a designer can take 1–3 months.
Permits come next where required. In 2026, City of Toronto residential permit reviews commonly take 2–6 weeks for straightforward projects and considerably longer for additions, Committee of Adjustment variances, or heritage properties. Mississauga, Vaughan, and Markham timelines are broadly similar. No legal structural, plumbing, or major electrical work should start without them.
Material ordering runs partly in parallel but has hard lead times: custom cabinets commonly take 6–10 weeks from final measure, windows 6–12 weeks, and specialty tile or plumbing fixtures can surprise you with 4–8 week waits. Good contractors will not start demolition until long-lead items are ordered and tracked. Then comes construction itself — the timelines above — and finally deficiencies: the punch-list phase of touch-ups, adjustments, and back-ordered items, which realistically takes 1–3 weeks after 'substantial completion.' Budget for it mentally so the last five percent does not feel like a betrayal.
Most delays trace back to a handful of predictable causes. Permit timing is the first: homeowners often sign a contract, then apply for permits, and lose four to eight weeks up front that nobody put in the schedule. Material lead times are the second — a kitchen cannot finish without its countertop, and countertops cannot be templated until cabinets are installed, creating a built-in 1–2 week pause that inexperienced planners miss.
Change orders are the self-inflicted delay: every mid-project decision to move a wall, upgrade tile, or add pot lights pauses work, re-sequences trades, and often triggers new material waits. A single significant change order commonly adds one to three weeks.
And then there is the GTA's housing stock itself. Toronto's older neighbourhoods — wartime bungalows in Scarborough, century semis in the east end, postwar homes across Etobicoke and North York — routinely hide knob-and-tube wiring, galvanized or lead plumbing, asbestos in plaster or floor tiles, and undocumented past 'renovations' behind the walls. Discovering any of these mid-demolition adds cost and time. Experienced contractors build contingency into schedules for pre-1970s homes; a 10–20% time buffer is prudent for any older-home project.
You have more control over the timeline than you might think. Finalize every selection before demolition day — flooring, tile, fixtures, paint colours, hardware. Projects where the homeowner has made all decisions up front run dramatically faster than projects where selections happen mid-stream. Order long-lead materials early and confirm delivery dates in writing before construction starts.
Insist on a written schedule with milestones, not just an end date — demolition complete, rough-ins complete, inspections passed, drywall, finishes — and review progress against it weekly. Respond to contractor questions within 24 hours; a surprising number of idle site days trace back to homeowners taking a week to choose a grout colour. Batch your change requests if changes are unavoidable, and keep a decision log so nothing gets relitigated. Finally, pick a contractor with capacity: a great renovator running six simultaneous jobs will move slower on yours than a good renovator running two.
Schedule slippage thrives in the dark — when homeowners do not know what was supposed to happen this week, they cannot catch a project drifting. SimplifyReno's milestone tracking makes the schedule visible: your contractor updates progress against defined milestones in the free app, so you see exactly where the project stands in real time instead of guessing from the state of the dust. Secure in-app messaging keeps every decision and approval time-stamped, which speeds responses on both sides.
