Quick Overview
- Vinyl is a solid, private fence. Aluminum or Ornamental is an open, see-through fence. That single difference decides most yards.
- Choose vinyl when privacy, shelter from wind, and quiet matter most. Choose aluminum for pools, front yards, sloped lots, and anywhere you want to keep the view.
- Ornamental does not rust and handles Ottawa winters without becoming brittle. Vinyl is low maintenance, but cold weather and hard impacts are its weak point.
- Both fall in a similar price range once installed, so the decision usually comes down to purpose, not cost.
- Pool enclosures in Ottawa have strict rules, and some popular aluminum and vinyl designs do not pass. Always check the specific panel design before ordering.
- Whichever material you pick, the posts and the depth they are set to matter as much as the panels.
The Core Difference: Solid vs. Open
Most of this decision comes down to one question: do you want to block the view, or keep it?
Vinyl fencing is built from solid, interlocking panels. It forms a continuous wall that blocks sightlines, softens street and neighbour noise, and cuts the wind. That makes it a natural choice for a backyard where privacy is the main goal.
Ornamental fencing is built from vertical pickets and horizontal rails. It marks a boundary and keeps a yard secure without hiding it. Wind and drifting snow pass through the gaps, and you keep your sightlines to the garden, a ravine, or the street.
Neither is better in general. They answer different questions, so start with what the fence needs to do.
How Each Material Handles an Ottawa Winter
Ottawa winters mean deep cold, repeated freezing and thawing, heavy snow, and road salt. Each material responds differently.
Aluminum stays rigid in the cold. It does not rust, and a quality powder-coated finish resists salt well. The main care it needs is a rinse in spring and a little lubricant on gate hinges and latches.
Vinyl Fence does not rot or rust either, but it is a plastic, and plastic becomes more brittle as temperatures drop. Good-quality vinyl is made with additives to keep it flexible, and it performs well in normal conditions. A hard knock in deep cold, such as a snowblower discharge, a shovel, or a heavy impact, is where cracking becomes possible. Solid panels can also take on more load from a snowbank piled against them, which is worth keeping in mind when you decide where the fence sits.
When comparing vinyl products, ask about cold-weather impact performance and wall thickness. Thin, budget panels are where most winter problems begin.
Strength, Repairs, and Appearance Over Time
Ornamental is the tougher material when something hits it. A hard impact may bend or dent a rail or picket, but individual sections can usually be replaced. The powder coat holds its colour well, so a replacement part installed years later tends to match the rest of the fence.
Vinyl cannot be patched or repainted. A cracked panel generally has to be replaced, and the new panel may look brighter than the older ones around it, because vinyl fades and can yellow slowly in the sun. Darker vinyl colours absorb more heat and put more stress on the panels as they expand and contract.
Vinyl does need an occasional wash. Dirt, pollen, and algae stick to it, especially in shaded or damp spots. Ornamental shrugs these off.
Which One Fits Which Yard
Backyard privacy. Vinyl. Solid panels give you immediate privacy, block sightlines into windows and patios, and reduce noise.
Pool enclosures. Usually aluminum. The open design lets you see the water from the house or deck, and the finish holds up to chlorine and salt. See the pool rules below, because not every panel qualifies.
Front yards. Usually aluminum. Ottawa limits front yard fences to 1 metre, and a short solid wall can feel closed off. An open fence at that height looks welcoming and keeps the yard visible.
Dogs. It depends on the dog. A solid vinyl fence works well for dogs that bark at everything that passes, because it removes what triggers them. Aluminum suits calmer dogs, The spacing between the pickets is standard and cannot be reduced.
Narrow side yards and tight lots. Often vinyl. Solid panels give privacy when windows sit close together, and the lighter pieces are easier to handle in tight spaces.
Ottawa Pool Rules That Affect Your Choice
If the fence is for a pool, the City of Ottawa’s Pool Enclosure By-law applies. It covers any outdoor body of water that can hold 24 inches (600 mm) or more, including hot tubs and above-ground pools. Key points:
- The enclosure must be at least 1.5 metres (5 feet) tall.
- No gap in the fence, including under the bottom rail, can let a 100 mm (4 inch) sphere pass through.
- Gates must self-close and self-latch, with the latch at least 1.35 metres above the ground on the pool side, and open away from the pool.
- Horizontal rails and other parts that could be used as footholds are restricted, so some designs with a mid-rail do not qualify. Confirm the specific panel against the by-law before you order, whichever material you choose.
- A permit is required (the 2026 fee is $257), and the enclosure must pass inspection before the pool can be filled.
Gate latch height depends on the gate post staying where it was installed, which is another reason foundation depth matters.
Height Rules for Any Fence
Under the City of Ottawa’s Fence By-law, front yard fences are limited to 1 metre, and side and rear yard fences to 2.13 metres. Within a corner visibility triangle, the limit drops to 75 centimetres. Height is measured from grade, and if the ground is higher on one side, the higher side is used. That detail matters on sloped lots.
What Sits Under the Fence
Panels get most of the attention, but frost heave is the main reason fences in Ottawa lean, twist, or stop closing properly. Ottawa soil holds water, and when it freezes, it pushes up on anything set too shallow. A solid vinyl fence also catches wind like a sail, so it relies heavily on its posts.
Posts need to be set below the frost line, which in Ottawa means a depth of roughly 3.5 to 4 feet. If you are comparing quotes from several fencing contractors Ottawa homeowners trust, ask each one exactly how the posts will be installed and how deep they will go. A well-built foundation protects any panel, vinyl or aluminum.
Cost
Installed prices in Ottawa generally run about $45 to $90 per linear foot for vinyl and $65 to $155 per linear foot for ornamental aluminum, depending on the style, the site, and the gates. Removing an old fence is a flat $12 per foot, and a pedestrian gate generally adds $500 to $1,500.
Long term, aluminum tends to cost less to own because it needs almost no care and parts can be replaced individually. Vinyl costs a little less upfront in many cases and is very easy to live with, as long as you buy a quality product and keep impacts in mind.
Which One Should You Choose?
Choose vinyl if your main goal is privacy, quiet, and wind protection in a backyard, and you are comfortable with an occasional wash.
Choose ornamental if the fence encloses a pool, runs across a front yard, or you want to keep the view and avoid maintenance.
If you are still undecided, think about the first thing you want the fence to do. Block the view, or frame it. The answer usually points to the right material. When you are ready to compare options for your own property, a professional team handling fencing installation Ottawa homeowners rely on can look at your slope, soil, and layout and tell you what will work.
FAQs
Which is better, vinyl or ornamental fencing?
Neither is better for every yard. Vinyl is better for privacy. Aluminum is better for pools, front yards, and open views.
Does vinyl crack in an Ottawa winter?
Good-quality vinyl performs well in most winter conditions. Cracking is most likely when a hard impact happens in very cold weather, or when the panels are thin and low quality.
Does aluminum (ornamental) fencing rust?
No. Aluminum does not form red rust. In heavy salt exposure it can develop a light, chalky film, but the metal stays sound.
Which fence is cheaper to install?
Vinyl is generally a little lower per foot, while ornamental covers a wider range depending on the style. Both fall in a similar band once installed.
Which needs less maintenance?
Ornamental needs the least. Vinyl needs an occasional wash to keep dirt and algae from building up.
Summary
Vinyl and aluminum are both strong choices for Ottawa, and they suit different jobs. Vinyl gives privacy, shelter, and a clean, solid look. Aluminum gives security, open views, and very low maintenance, and it is the usual choice for pools, front yards, and. Match the material to what the fence needs to do, check the pool and height rules if they apply, and make sure the posts are set deep enough to handle Ottawa’s frost.
