Oakville yards lean formal: crisp cedar walls, boxwood edging, yew around the foundation and long privacy hedges on lots backing onto each other. Keeping them sharp takes regular trimming at the right time of year. Here is what it costs, what the Town limits, and how to keep a hedge dense from top to bottom.
2026 hedge trimming prices in Oakville
| Job | Typical 2026 price |
|---|---|
| Cedar hedge shaping, sides and top, clippings hauled | $18 - $32 per linear metre |
| Shrub pruning (boxwood, yew, spirea, hydrangea and similar) | $45 - $120 per shrub |
| Lowering an overgrown hedge, or tying and wrapping for winter | Quoted on site |
We quote by the linear metre of hedge, then adjust for height, width and access. Hedges over about 2.5 m need a platform or lift. Formal hedges with sharp, square edges take longer than a loose, natural shape. Low boxwood or yew edging along beds is priced per shrub or per run. Customers on a once-or-twice-a-year schedule pay less per visit, because the growth is lighter and quicker to clean up.
Visibility triangles in Oakville
Oakville's zoning rules treat hedges the same way as fences near the street, and the limit is lower than many people expect:
| Location | Triangle size | Maximum hedge or fence height |
|---|---|---|
| Corner lot, where two streets meet | 10.67 m along each street line from the corner | 0.91 m (3 ft) |
| Where your driveway meets the street | 2 m triangles either side of the driveway | 0.91 m (3 ft) |
A cedar hedge planted at the corner of a lot in Joshua Creek or West Oak Trails can easily reach 2 m within a few years and block the view for every driver turning the corner. If yours is in a triangle, we can lower it in stages so it stays green, or recommend moving that section back and replacing it with something that stays low naturally, such as dwarf boxwood, spirea or low yew. Our Oakville fence page covers the fence side of the same rules.
Shaping a hedge that stays green to the ground
The most common problem we see in Oakville is a hedge that is full at the top and thin or bare at the bottom. The cause is almost always shape. A hedge cut straight up and down, or wider at the top, shades its own lower branches until they die.
- Batter the sides: trim so the hedge is a little narrower at the top than the base, roughly 15 cm narrower for every metre of height. Light then reaches the whole face.
- Round or slope the top on tall cedars so snow slides off instead of piling up and splitting the stems.
- Never cut cedar into brown wood. Cedar does not regrow from bare interior wood. Leave a layer of green on every face.
- Trim little and often. Two light trims a season keep a hedge denser than one hard cut.
The right time to trim each hedge
- Cedar: June, after the spring flush, and lightly again in late August if you like a sharp look. No hard cuts after mid-September.
- Boxwood: early summer. Look inside the plant for webbing and green caterpillars of box tree moth, which strips boxwood fast in southern Ontario.
- Yew: early summer. Yew is the one evergreen that will sprout from old wood, so it can be renovated hard.
- Beech and hornbeam hedges: late July to August. A late trim helps them hold their dry leaves through winter, which keeps some privacy.
- Flowering shrubs such as lilac, forsythia and weigela: right after flowering.
Most of that falls in nesting season. The federal nesting period guidance puts the main nesting period from about early April to late August, and thick hedges are prime nest sites. We look before we cut, and skip any section with an active nest.
Old Oakville and heritage streets
Old Oakville sits inside a heritage conservation district, and many of its older homes are framed by mature hedges that are part of the street's character. Trimming a hedge needs no permit. If you are thinking of removing a front hedge and replacing it with a fence or wall, check with the Town's heritage staff first, because front-yard structures there are reviewed. A hedge that has got too big is usually better reduced over a couple of seasons than replaced.
Neighbour hedges along the back line
Many Oakville backyards are divided by a cedar hedge planted on or near the line. If the plants are on the line, they may be jointly owned. Ontario's Forestry Act treats trees on a boundary as common property, and injuring one without your neighbour's consent is an offence. You can usually trim your side, but agree any height reduction with the neighbour. Oakville's division fence rules cover sharing the cost of a fence, not a hedge, so hedge costs are something to agree between you.
Winter protection
Before the first heavy snow, tie tall, narrow cedars loosely with soft tie so snow load cannot pull them open. Along busy roads such as Rebecca, Lakeshore and Upper Middle, a burlap screen on stakes, set a little away from the hedge, cuts salt spray. Do not wrap cedars tightly in plastic. We can quote tying and wrapping with your fall cleanup.

Frequently asked questions
How much does hedge trimming cost in Oakville?
About $18 to $32 per linear metre of cedar hedge with cleanup, and $45 to $120 per shrub. A 30 m hedge costs roughly $540 to $960.
How tall can a hedge be at a corner in Oakville?
No more than 0.91 m inside the 10.67 m visibility triangle at a street corner, or the 2 m triangle where a driveway meets the street.
Why is my cedar hedge bare at the bottom?
Usually because it is cut wider at the top, shading the lower branches. Trim it slightly narrower at the top so light reaches the base.
When is the best time to trim cedar hedges in Oakville?
June, after the spring growth, with an optional light trim in late August. Avoid hard cuts after mid-September.
Do I need a permit to trim a hedge in Oakville?
No. Replacing a front hedge with a fence or wall in the Old Oakville heritage district may need heritage review.
Who pays to trim a hedge on the property line?
It is up to you and your neighbour. Oakville's division fence rules cover fences, not hedges, so agree the work and cost between you.
