Ballpark ranges only, not a quote: wood pergolas -- Peter's own lane -- generally run $6,000-$16,000 in Ontario/GTA 2026 marketing-content pricing, or roughly $50-75/sq ft. For comparison only (not Peter's product): aluminum pergolas commonly run $10,000-$22,000, and can climb to $45,000+ once motorization, louvered roofs, or lighting are added, at roughly $80-130/sq ft. These are wide, self-serving ranges, not a fixed price -- your actual cost depends on size, materials, and attachment style. Book a real estimate for a number you can rely on.
A freestanding wood pergola in Ontario usually does NOT need a building permit. A permit generally IS required if the footprint exceeds roughly 10 m2 (about 108 sq ft), if the pergola is attached to the house, or if a solid/permanent roof is added -- a permanent roof brings the structure back into building-permit review for snow-load and wind-load reasons. We have not confirmed a Niagara-specific snow-load figure for that review, so we state the principle only -- confirm engineering and permit specifics for any roofed pergola with your municipality. Even when no building permit is required, zoning setbacks and height rules still apply, so check those before you build. Attachment style changes the picture: a freestanding pergola set away from the house is the most likely to stay permit-exempt (subject to the footprint threshold above); a deck-mounted pergola built on top of an existing deck generally follows whatever permit status the deck itself already carries, plus the same roof-triggers-review principle if you cover it; and a house-attached pergola is the most likely to require a permit outright, both because attachment is itself a trigger and because it ties into the house's existing structure. Confirm the current rule and any zoning setback with Niagara Falls, St. Catharines, or Niagara-on-the-Lake's own building department before building, since each administers its own process.
Wood pergolas cost less upfront ($6,000-$16,000 versus aluminum's $10,000-$22,000+) and give a natural, timber look, but in Ontario's climate they need periodic re-staining or sealing and generally last around 10-15 years before major structural work is needed. Aluminum pergolas cost more upfront, need essentially no annual finishing, generally last around 15-25 years, and can be built with motorized or louvered roofs and integrated lighting -- options that push cost well past $45,000. Peter builds wood, not aluminum -- if you're set on a motorized louvered roof, that's a different (metal-fab) product outside his current lane, and we'll tell you that honestly rather than stretch to fit it. Stating that plainly, even though it means sending some inquiries elsewhere, is what earns trust over a sales pitch.

Usually no for a freestanding pergola. A permit is generally required if the footprint is bigger than about 10 m2 (108 sq ft), if it's attached to the house, or if you add a solid/permanent roof (which triggers snow-load and wind-load review). Even without a permit, zoning setbacks and height rules still apply -- confirm with your own municipality before building.
A pergola has an open roof of beams or rafters that light passes through. A gazebo has a solid roof and is typically polygonal (six- or eight-sided). A pavilion has a solid, A-frame-style roof. Knowing which one you actually want affects both the look and the permit picture, since a solid roof changes the permit-review answer above.
Generally around 10-15 years for wood, versus roughly 15-25 years for aluminum. Wood needs periodic re-staining or sealing to hold up over that span; aluminum needs little to no annual finishing but costs more upfront.
Yes -- a deck-mounted pergola is a common option. It generally follows whatever permit status your existing deck already carries, but adding a permanent or solid cover on top can bring the project back into permit review for snow-load and wind-load reasons, even if the deck itself is otherwise exempt. Confirm the specifics with your municipality before building.
