Costs
3 cost questions for a covered patio in Ontario, from permits to labour
Covered patio costs in Ontario come down to three questions: permit fees, Toronto and Ottawa labour rates, and material prices. Here are sample budgets for both.
What to take away
- A covered patio in Ontario usually needs a building permit once the roof is supported by posts or attaches to the house.
- Permit fees vary by municipality and by construction value, so confirm the fee schedule before you sign a contract.
- Toronto labour rates run higher than Ottawa rates for the same framing and roofing work.
- Roof, post and footing material prices move with lumber and concrete markets, so get quotes dated within 30 days.
- A realistic covered patio budget for Toronto or Ottawa starts with measured quantities, not a national average.
- Two bids can look identical until you compare exclusions, allowances and permit responsibility line by line.
The three cost questions that decide an Ontario covered patio budget
Every covered patio budget in Ontario rests on three questions. Is a permit required, and what will it cost? What do Toronto or Ottawa contractors charge for labour? What will the roof, posts and footings cost in materials?
Answer those three and the rest of the budget is arithmetic. Skip them and you are guessing.
A covered patio is not a deck with a hat. It carries roof loads, wind uplift and snow load, and Ontario's design requirements follow the National Building Code of Canada as adopted provincially. That changes footing size, post spacing and roof framing compared with an open deck.
Start with the permit question, because it decides whether your project timeline and budget include drawings, reviews and inspections. Then price labour and materials using local numbers, not a national average.
The dollar figures below are Ontario planning ranges drawn from contractor billing, supplier lists and municipal fee schedules. Treat them as budget anchors and replace each one with a dated local quote.
If you want the permit rules in detail before you budget, see our guide to whether you need a building permit for a covered patio.
Ontario permit fees and when a covered patio needs one
Ontario building permit rules are set by each municipality under the Building Code Act, 1992, and the province's statute framework is published on e-Laws | Ontario.ca. The act gives municipalities the authority to require permits and set fees.
The permit threshold for a covered patio
Most Ontario municipalities require a permit once a roofed structure passes 10 square metres of footprint, about 108 square feet. Below that, a detached garden structure is often exempt.
Size is not the only trigger. A covered patio more than 600 mm above grade, roughly two feet, needs a permit in most Ontario cities because it has footings and a guard requirement.
Anything attached to the house is treated as part of the building. An attached roofed patio needs a permit no matter how small it is, and the house connection is reviewed as structural work.
So the practical threshold for a covered patio is simple: attached, or roofed with footings over 10 square metres, or standing more than 600 mm above grade. Meet any one and you are applying.
What Toronto charges
The City of Toronto publishes its building permit requirements and fee schedules on its Building Permits – City of Toronto page. Fees are calculated from the value of construction, so a larger covered patio pays more.
Toronto planning range: $450 to $800 for a project valued near $20,000. At $30,000 to $40,000 of construction value, expect $700 to $1,100. A design or engineering stamp adds $300 to $900.
Toronto also requires drawings that show footing depth, post connections, beam sizing and roof framing. You will need a site plan and construction details. The city lists the required forms and supporting documents on its Forms, Documents, & Additional Resources – City of Toronto page.
Budget for the permit fee, plus the cost of drawings if your contractor does not include them. Add the revision fee, often $100 to $250, if you change the design after submission.
What Ottawa and other Ontario cities charge
Ottawa planning range: $300 to $600 for the same small covered patio, and $500 to $850 at the higher value band. Mississauga and Hamilton sit in a similar range. Smaller municipalities often charge $200 to $500.
Ottawa, Mississauga, Hamilton and smaller Ontario municipalities each publish their own fee schedules. Fees are usually tied to project value, with a minimum charge. Some cities add a zoning review fee or a separate inspection fee.
Do not assume the Toronto fee applies in Ottawa. Call the local permit office or check its website before you finalize the budget. A difference of a few hundred dollars is common between municipalities for the same project.
Permit fees are a small share of the total, but they are a fixed cost you cannot negotiate away. Include them as a line item, not as a contingency.
Contractor labour rates in Toronto and Ottawa
Labour is the largest single line in most covered patio budgets. Rates differ between Toronto and Ottawa because of market demand, travel time and the availability of skilled framers and roofers.
The rates below are typical contractor billing rates, which include the crew's wage, payroll costs and a share of overhead. They are not take-home pay.
| Trade | Toronto | Ottawa |
|---|---|---|
| Carpenter, framing | $75 to $95 per hour | $65 to $85 per hour |
| Roofer | $65 to $85 per hour | $58 to $75 per hour |
| Concrete finisher | $70 to $90 per hour | $62 to $82 per hour |
| Licensed electrician | $95 to $130 per hour | $85 to $115 per hour |
| General labourer | $45 to $60 per hour | $40 to $52 per hour |
Toronto contractor labour rates
Toronto rates reflect a dense, busy market. Carpenters, roofers and concrete crews charge more per hour, and contractors add overhead for parking, permits and site access. Expect Toronto labour to sit at the top of the Ontario range.
A Toronto contractor may also charge for a site supervisor, a bin permit and a hoist or crane if materials cannot be carried in. Those costs do not appear in Ottawa quotes as often.
Ottawa contractor labour rates
Ottawa rates are typically lower than Toronto rates for the same scope, usually by 10 to 20 percent. On a three or four week covered patio build that gap is worth roughly $1,000 to $1,500.
Ottawa winters shorten the building season, so scheduling matters. A late-season start can mean premium rates or a spring start. That affects the budget as much as the hourly rate.
How labour is quoted
Most contractors quote a lump sum rather than an hourly rate. A two-week covered patio build is often billed as a package: $9,000 to $14,000 in Toronto, $8,000 to $12,000 in Ottawa, for framing and roofing alone.
Ask for the labour breakdown: framing hours, roofing hours, concrete hours and finishing hours. A lump sum with no breakdown is hard to compare.
Statcan publishes construction cost and activity data that helps you sanity-check a quote against broader market trends, at Construction statistics. If a quote is far above or below the trend, ask why.
Material prices: roof, posts, footings and finishes
Material prices for a covered patio fall into four groups: the roof, the posts, the footings and the finishes. Each behaves differently.
The table gives Ontario supply prices you can use as anchors. Delivery, tax and waste are extra.
Show the numbers
| Pressure-treated 6x6 post, 8 ft | $35–$70 |
|---|---|
| Cedar 6x6 post, 8 ft | $85–$150 |
| Engineered column, 8 ft | $220–$500 |
| Pressure-treated beam, built up | $12–$25 |
| Asphalt shingles | $45–$65 |
| Standing seam metal roofing | $10–$20 |
| Concrete, delivered | $200–$270 |
| Rebar, 15M | $12–$20 |
| Aluminium soffit | $3–$6 |
Roof materials
Roof choices include asphalt shingles, metal standing seam, cedar shakes and composite panels. Asphalt shingles cost the least per square foot and are the most common. A 16 by 14 foot patio needs roughly nine squares, so $2,000 to $3,000 in shingle material with underlayment and flashing.
Metal roofing costs more but lasts longer and handles snow shedding differently. The same roof in standing seam runs $4,000 to $8,000 in material alone.
The roof structure matters as much as the surface. Rafters, trusses, sheathing and fascia are priced separately. A simple gable roof costs less to frame than a hip roof with valleys.
Posts and beams
Posts are usually pressure-treated lumber, cedar or engineered columns. Cedar costs more than pressure-treated but needs less finishing. Engineered columns cost more again but give predictable strength and straight lines.
A typical covered patio uses four to six posts. At $35 to $70 each, pressure-treated posts are a modest line. Switch to engineered columns and the same run costs $900 to $3,000.
Beam sizing depends on span and snow load. A longer span needs a deeper beam, which costs more. This is where a covered patio budget can move quickly if the design changes.
Footings
Footings are concrete, and their cost depends on depth, diameter and how many you need. Ontario frost depth drives footing depth, typically 1.2 to 1.5 metres below grade, so footings are deeper here than in milder climates. That is a real cost difference from US advice you may find online.
A 12 inch diameter footing at 1.5 metres deep takes about 0.27 cubic metres of concrete. Six of those is under two cubic metres, so $400 to $550 in concrete, before excavation, formwork and rebar.
Concrete is priced by volume, plus excavation, formwork and rebar. If the ground is hard to access, add labour for hand digging.
Finishes
Finishes include soffit, fascia, railings, lighting, ceiling material and stain or paint. These are the easiest items to upgrade and the easiest to cut. Decide which finishes are essential before you compare bids.
A basic soffit and fascia package runs $3 to $6 per square foot in material. Railings run $60 to $150 per linear foot installed. Lighting is often $1,500 to $2,500 installed.

Sample budgets for Toronto and Ottawa builds
The table below shows a worked example for a 16 by 14 foot covered patio attached to a house. The Toronto column reflects higher labour and permit costs. The Ottawa column reflects lower labour rates and a different fee schedule.
| Line item | Toronto sample | Ottawa sample |
|---|---|---|
| Permit fee and drawings | $1,400 | $1,100 |
| Excavation and footings | $3,200 | $2,900 |
| Posts and beams | $3,600 | $3,300 |
| Roof framing and sheathing | $4,800 | $4,400 |
| Roofing surface | $2,600 | $2,400 |
| Soffit, fascia and ceiling | $2,200 | $2,000 |
| Railings and stairs | $2,400 | $2,200 |
| Electrical and lighting | $1,600 | $1,500 |
| Labour, general conditions | $8,500 | $7,200 |
| Contingency at 10 percent | $3,000 | $2,700 |
| Total | $33,300 | $29,700 |
These are illustrative figures for budgeting, not quotes. Your numbers will move with design, site access and material choices.
The Toronto total is higher mainly because of labour and permit costs. The Ottawa total is lower, but the margin is not so wide that you should assume a bargain. Both cities have busy contractors and long waits in spring.
If you want to build your own estimate from measured quantities, our guide on how to price a covered patio walks through the line items that add up.
A worked example: changing one variable
Take the Toronto sample and change the roof from asphalt shingles to standing seam metal. The roofing surface line moves from $2,600 to roughly $5,000, and the framing may need different fasteners and clips. The total rises by about $2,500.
Now change the roof shape from a simple gable to a hip with two valleys. Framing labour rises, waste rises and the roofing surface area rises by about 15 percent. The budget moves again.
Swap pressure-treated posts for cedar and add another $400. Add six engineered columns instead and add closer to $1,500.
This is why a covered patio budget should be built from quantities, not copied from a national average. Our article on a patio budget built from quantities explains the method.
Where budgets quietly overrun on covered patio work
Overruns rarely come from the roof. They come from the ground and the edges of the job.
- Footing depth or diameter increases after the inspector reviews the soil.
- Site access requires hand digging or a smaller machine.
- The house connection needs flashing, siding repair or a new ledger.
- Electrical work needs a separate permit and a licensed electrician.
- Finishes are upgraded after the contract is signed.
- Winter conditions add heating, hoarding or delay costs.
- Changes to the design after permit submission trigger a revision fee.
Each of these can add hundreds or thousands of dollars. Hand digging instead of a machine can add $2,000. A new ledger and flashing can add $800 to $1,500. None of them is unusual on an Ontario covered patio.
A contingency of 10 to 15 percent is not padding. It is the line that keeps the project from stalling when the ground turns out to be harder than expected.

How to compare two Ontario contractor bids
Two bids for the same covered patio can differ by thousands of dollars and still both be honest. The difference is usually in what is included, not in the price of the same work.
Compare bids in this order:
- Check that both bids cover the same scope: footings, posts, beams, roof, finishes and electrical.
- Check who pulls the permit and who pays the fee.
- Check the drawings: are they included, and who stamps them?
- Check allowances for finishes and lighting, and ask what happens if you exceed them.
- Check the schedule, including start date, weather delays and payment milestones.
- Check the exclusions, which are often where the cheaper bid hides its savings.
A bid that excludes the permit, the drawings or the electrical is not cheaper. It is incomplete.
Watch the allowances. A $1,000 lighting allowance and a $2,500 lighting allowance sit in the same looking bid, and the second is closer to reality.
Ask each contractor for a labour and material breakdown. Ask for references from covered patio projects in the same municipality. Ask what happens if the footing inspection requires a change.
The lowest bid is rarely the lowest final cost. The clearest bid usually is.
Common questions
Does a covered patio always need a permit in Ontario? No. An open patio at grade usually does not. A roofed structure over about 10 square metres, one more than 600 mm above grade, or any attached roof generally does. Check with your municipality.
Are Toronto permit fees higher than Ottawa fees? They can be. A small covered patio runs about $450 to $800 in Toronto and $300 to $600 in Ottawa, because fees are tied to construction value and each city sets its own schedule.
Why is Toronto labour more expensive than Ottawa labour? Toronto framing crews bill about $75 to $95 per hour against $65 to $85 in Ottawa. The market is denser and contractors carry more overhead for access, parking and supervision.
How much contingency should I hold for a covered patio? Ten to 15 percent of the construction cost is a reasonable starting point. Footing changes, house connections and electrical work are the most common sources of overrun.
Can I use a national average to budget my covered patio? No. Ontario frost depth drives footings 1.2 to 1.5 metres deep, local permit fees differ, and Toronto or Ottawa labour rates both sit above national figures. Build the budget from quantities and local quotes.
