Sheep Farming in Canada: Winter Housing, Lambing and Records
Sheep farming in Canada: main provinces, breeds, winter barns, accelerated lambing, predators and national ID, plus the records that keep a flock profitable.

Sheep farming in Canada is shaped by winter. Most flocks spend the cold months in barns, eat stored forage, and many lamb indoors in winter or early spring. The largest flocks are found in Ontario and Québec, with significant production in Alberta and the other Prairie provinces. A profitable Canadian flock combines a dry, well-ventilated barn, a planned lambing calendar, good predator protection and precise records for every ewe.
Canadian lamb is in demand: many consumers want fresh local lamb, and communities that celebrate Eid al-Adha, Easter or other holidays create clear seasonal peaks. At the same time, imported lamb competes on price, so local producers win on freshness, timing and consistency, which all depend on good management.
Where sheep are raised in Canada
- Ontario has a large number of farms, from small hobby flocks to commercial operations, and is close to big urban markets such as the Greater Toronto Area.
- Québec has a structured sheep sector, many farms lambing several times a year, and a strong market for local lamb, including heavy lambs.
- Alberta and the Prairies run larger flocks on more land, with more grazing and range in summer and stored feed in winter.
- Atlantic Canada and British Columbia have smaller but active sheep communities.
Common breeds include Dorset, Suffolk, Texel, Rideau Arcott (developed in Canada), Romanov and Polypay, as well as hair breeds such as Katahdin. Prolific and out-of-season breeds are popular in systems that lamb more than once a year.
Winter housing: dry, ventilated, not warm
Adult sheep with a full fleece tolerate cold well. What they do not tolerate is damp, draughts and stale air. A good winter barn is:
- Dry: deep, clean bedding (straw or similar) and good drainage. Wet fleece loses its insulation.
- Ventilated: open ridges, curtains or fans that remove moisture and ammonia without blowing on the animals. Poor ventilation is a major cause of pneumonia in lambs.
- Organised by group: late-pregnant ewes, lambing pens, ewes with lambs, growing lambs, rams and an isolation pen.
- Supplied with unfrozen water: heated waterers or regular checks; snow is not enough as the only water source.
- Stocked with tested forage: have hay or haylage analysed so you know what the ewes are really getting, then balance with grain and minerals.
Many farmers shear before lambing in the barn; shorn ewes take less space and seek shelter for their lambs. Newborn lambs need a sheltered, draught-free spot. If you use heat lamps, secure them carefully: barn fires are a real winter risk.
Lambing in winter and accelerated lambing
Ewe gestation lasts about 147 days. Canadian flocks typically choose between:
- Winter lambing (January to March): lambs reach market weight in time for spring and early summer holidays and grow before pasture season. It needs a good barn and close supervision.
- Spring lambing on pasture: lower housing costs, but more exposure to weather and predators, and lambs sell later.
- Accelerated lambing: splitting the flock into groups that lamb several times a year, for example the 3 lambings in 2 years system. It evens out labour and lamb supply, but needs prolific breeds that cycle out of season, excellent nutrition and very good records.
Whatever the system, prepare the ewes with good body condition and flushing before mating, check them often at lambing, make sure every lamb gets colostrum and tag lambs early.
Predators, grazing and biosecurity
Coyotes are the most common predator for sheep in much of Canada, and wolves, bears and dogs can also cause losses depending on the region. Common protection measures are livestock guardian dogs, good electric or woven-wire fencing, night penning and removing dead animals quickly. Some provinces have programmes or rules around predation losses; check what applies in your province.
In summer, rotational grazing improves pasture use and helps control worms; plan worming with your vet. Isolate newly bought animals before mixing them with the flock, and follow the vaccination programme your vet recommends for your area.
Identification and traceability
Canada has a mandatory national identification system for sheep: animals must carry approved ear tags before leaving their farm of origin, and movements are subject to traceability rules. Québec also runs its own provincial traceability requirements. Rules are updated from time to time, so confirm the current requirements with the national program administrator, the Canadian Food Inspection Agency and, in Québec, the provincial agency before buying or selling animals.
Official tags are the legal minimum. For management, you also need a link between each tag and the animal's dam, birth date, weights and treatments. Our list of what to record on a sheep farm is a good starting point.
Records that keep a Canadian flock profitable
Winter feed is usually the largest cost, so every unproductive ewe is expensive to carry through the cold months. Records answer the key questions:
- Which ewes lambed, how many lambs, and how many were weaned?
- How fast do lambs grow between birth, weaning and sale?
- Which ewes should be culled before winter?
- What does each lamb cost to produce, including feed and bedding?
On the Throf platform, each ewe and lamb has its own record (tag number and colour, RFID supported, breed, dam, weights), with matings, lambings, twins and triplets, health alerts and reminders, expenses, sales and cost per head. The app works in English, French and Arabic on phone, laptop and tablet, and team members get their own permissions, which helps on farms where a family and hired staff share the barn work.

FAQ
Can sheep stay outside in a Canadian winter?
Adult sheep with a full fleece tolerate cold well if they are dry and have shelter from wind, but most Canadian flocks are housed in winter, especially for lambing, and they always need unfrozen water and enough forage.
When do Canadian farmers lamb?
Many lamb indoors from January to March, others lamb on spring pasture, and some flocks use accelerated systems with several lambing groups a year.
Do sheep need ear tags in Canada?
Yes. Canada has a mandatory national identification system for sheep, and Québec has its own provincial traceability rules; confirm the current requirements before moving or selling animals.
Which province has the most sheep in Canada?
Ontario and Québec have the largest share of sheep farms, with Alberta and the other Prairie provinces also important.
