Choosing a fence for a hobby farm in Canada involves more variables than most agricultural guides acknowledge. The frost line, the species you're containing, the perimeter length, and your tolerance for annual maintenance all pull in different directions. What works on a five-acre sheep operation in Prince Edward Island doesn't automatically transfer to a ten-acre mixed property in the Peace Region of Alberta.
This overview covers the five fence types most commonly installed on Canadian hobby farms, with honest notes about where each type creates problems over time.
Electric Fencing
Single-strand and multi-strand electric fencing remains the most cost-effective option for temporary subdivision within a larger perimeter. A basic single-strand system with a 1-joule energiser, fibreglass step-in posts, and polywire costs roughly CAD $0.30 to $0.60 per metre of fence, depending on post spacing and wire specification.
The limitation with electric fence in Canada is grounding. Frozen or dry soil conducts poorly. An energiser that delivers a reliable shock in June may underperform significantly in November. Running a ground return wire — a second strand close to ground level connected back to the energiser — compensates for this in most conditions, but adds to the installation cost and the amount of wire to manage.
What Species Work with Electric
- Cattle respond well to a single or double strand at nose height once trained.
- Horses require more strands and often additional visual definition such as polytape to prevent fence collisions at speed.
- Sheep and goats are more difficult — they test fences more persistently and will exploit any grounding weakness.
- Pigs generally respond well to a single low strand once the initial training period is complete.
Woven Wire (Field Fence)
Galvanised woven wire in the standard fixed-knot pattern, typically 90 cm to 120 cm tall with 15 cm × 15 cm opening patterns, is the most versatile permanent fence option for mixed livestock properties. Per metre costs run CAD $2.50 to $4.50 installed, depending on whether you're pulling the wire yourself or contracting the installation.
Woven wire holds its shape better than high-tensile in terrain with significant grade changes, because the fixed knot absorbs movement at each intersection rather than transmitting tension across a long span. It does not require the same level of bracing infrastructure as high-tensile, but corner and end posts still need to be substantial — a minimum of 150 mm diameter treated post driven to below the local frost line.
Frost Heave and Post Depth
In most of Ontario, Quebec, and the Prairie provinces, the frost line sits between 1.2 and 1.8 metres. Posts driven or augured to that depth — or set in concrete below the frost line — will not heave. Posts that are set shallower, even with good compaction around them, can push upward over several freeze-thaw cycles and eventually loosen the wire. This is a common failure mode on older fence lines installed without attention to the local frost depth.
Natural Resources Canada maintains frost line depth maps for most populated regions of the country. The Natural Resources Canada geoscience data portal is a useful reference before purchasing post stock for a new installation.
High-Tensile Wire Fencing
High-tensile smooth wire, typically 12.5 gauge, is installed under tension between substantial anchor assemblies at corners and ends. A five- to eight-strand high-tensile fence with a good in-line strainer and proper brace assemblies can span longer distances between line posts than woven wire — up to nine metres between posts in flat terrain — which reduces material costs on long perimeter runs.
The system requires accurate tensioning. Under-tensioned wire sags and loses containment integrity. Over-tensioned wire breaks during temperature contraction in cold weather. Most commercial installers aim for approximately 200 kg of tension per wire in the Canadian climate, with spring tightening as a standard annual maintenance task.
High-tensile is not a good choice for horses or small ruminants without additional measures. Horses can run into it without seeing it clearly, and sheep can push under lower strands if spacing isn't calculated correctly for the species.
Barbed Wire
Barbed wire is legal and still widely used on cattle operations in Canada, but has fallen out of favour on hobby farms for several reasons. It causes lacerations when animals push against it — a particular concern with horses. It is not suitable for sheep or goat containment without companion strands of electric wire at low heights. The upside is cost: barbed wire is one of the cheapest permanent perimeter options at CAD $1.50 to $2.50 per metre installed.
For beef cattle operations with large acreage and long perimeter runs, three- or four-strand barbed wire remains practical and effective. On smaller properties with diverse livestock species, woven wire or high-tensile is generally a better long-term investment.
Post-and-Rail (Wood and Vinyl)
Split rail cedar or pressure-treated pine post-and-rail is the most visually clean option for properties where the fence line is highly visible. It is also the most expensive for long runs, and requires more frequent inspection for rot, breakage, and shifting post alignment.
Cedar split rail is dimensionally unstable — it warps and twists over time, which means the rails eventually work loose from the post mortises. Pressure-treated lumber is more dimensionally stable but carries its own concerns around soil contact and the treatment chemicals used in different product lines.
Vinyl post-and-rail has become more common on horse properties where appearance is a priority. It requires no painting, resists rot, and doesn't splinter. The failure mode is brittleness in very cold temperatures — vinyl becomes less impact-resistant below -20°C, which is relevant in northern Ontario and the Prairie provinces.

Choosing Based on Your Situation
A few questions help narrow the decision faster than any general comparison table:
- What species are you containing? Cattle are the most tolerant of fence type variation. Horses and sheep have specific requirements that eliminate some options outright.
- What is your perimeter length? Long perimeters favour high-tensile for cost. Short, visible perimeters may justify post-and-rail.
- Do you need internal subdivision? If you're planning a rotational system, temporary electric for internal paddock fencing combined with a permanent perimeter is the most cost-effective approach.
- What is your maintenance tolerance? Electric requires the most ongoing attention. Woven wire in appropriate gauge is the lowest-maintenance permanent option over a ten-year horizon.
Agriculture Canada's AgriService portal includes province-specific cost-share programs that may offset a portion of permanent fencing installation costs on eligible livestock properties. Eligibility varies by province and program year.
