Quick answer
A pond that can hold more than 0.6 m (2 ft) of water counts as a pool under Hamilton By-law 16-184 and Oakville By-law 2006-071, so it needs a permit and an enclosure. Hamilton lets a landscape pond use a securely fastened grate with openings no more than 38 mm instead. Burlington's 74-2005 doesn't name ponds; we confirm with the City.
When does a pond count as a pool?
Each by-law sets its own depth threshold.
| City | By-law | Threshold | Ponds |
|---|---|---|---|
| Hamilton | 16-184 | Wholly or partly artificially contained and able to hold more than 0.6 m of water at any point | Named: "including but not limited to a hot tub or landscape pond" |
| Oakville | 2006-071, s. 1(g) | More than 0.61 m deep at some point, exposed surface at least 1 m² | Named: "includes a hot tub or landscape pond meeting the above criteria" |
| Burlington | 74-2005, s. 2.1.5 | Tank or body of water used or intended for swimming or display purposes, able to hold more than 600 mm | Not named; a man-made display pond deeper than 600 mm could fall within it (our reading; we confirm with the City) |
By-laws change; we confirm the rules and permit for your lot before we dig.
What is Hamilton's grate option?
Section 16 of By-law 16-184 lets a landscape pond use a securely fastened grate or similar structure instead of an enclosure. It must prevent a person of any size from descending deeper than 0.6 m, with openings of not more than 38 mm. Otherwise a full enclosure is required.
Are rural and farm ponds treated differently?
Hamilton By-law 16-184 excludes livestock or irrigation water on farmland, and bodies of water on rural or agricultural land that can't hold more than 0.6 m within 2.0 m of the edge.
Oakville By-law 2006-071 excludes farm and golf ponds, natural water and stormwater facilities.
Burlington's definition excludes natural water. On a country lot, see country & estate properties.
Do I need a permit first?
In Hamilton, yes: a permit before building (By-law 16-184, ss. 5–6). If your pond will be deep enough to count as a pool, plan the permit and the enclosure or grate before anything is dug.
Where are the fence rules for my city?
Once a pond counts as a pool, the pool enclosure rules apply. See pools in Hamilton, pools in Burlington and pools in Oakville.
Frequently asked questions
Does my koi pond need a fence?
If it can hold more than 0.6 m of water, likely yes in Hamilton and Oakville, which name landscape ponds in their pool by-laws. Hamilton allows a securely fastened grate with openings no more than 38 mm instead of an enclosure (By-law 16-184, s. 16).
How deep can a pond be without a fence?
Hamilton's threshold is more than 0.6 m of water at any point; Oakville's is more than 0.61 m deep with at least 1 m² of surface. Under those depths the pool rules don't apply. Burlington's 74-2005 uses 600 mm for display pools.
Does Burlington treat ponds as pools?
Its By-law 74-2005 doesn't name ponds. It covers privately owned outdoor bodies of water used for swimming or display purposes that can hold more than 600 mm, so a man-made display pond that deep could fall within it. That's our reading; we confirm with the City.
What about a pond on a farm?
Hamilton excludes livestock or irrigation water on farmland, and bodies of water on rural or agricultural land that can't hold more than 0.6 m within 2.0 m of the edge. Oakville excludes farm and golf ponds, natural water and stormwater facilities.
Is a pondless waterfall a pool?
It has no open, deep water: the water is stored in a rock-filled basin. That's why we suggest pondless waterfalls and fountains when you want moving water without the pond depth issue.
Do I need a permit before building a pond?
In Hamilton, a pond deep enough to count as a pool needs a permit before building (By-law 16-184, ss. 5–6). We confirm the rules for your lot before we dig.
