A Season of Caution
For most Canadians, the return of geese and other migratory birds is a welcome sign that winter is finally loosening its grip. But for Alberta's poultry farmers, spring migration triggers a very different kind of watchfulness, one shaped by painful memories of last year's devastating avian influenza outbreak.
Last year's avian flu season was widely described as one of the worst in years, hitting commercial poultry operations across the Prairies hard. Flocks were culled, livelihoods were disrupted, and the industry scrambled to contain the spread. Now, with birds returning from their southern wintering grounds, farmers are determined not to repeat the experience.
What Makes Spring So Risky
Highly pathogenic avian influenza (HPAI) spreads primarily through contact with infected wild birds, their droppings, feathers, or contaminated water sources. The spring and fall migrations are peak risk periods because millions of waterfowl and shorebirds move through Canadian flyways, passing over and near agricultural land.
Alberta sits along one of North America's busiest migratory corridors, making its poultry sector particularly vulnerable. A single infected wild bird near an open-concept barn or outdoor run can trigger a chain of transmission that decimates an entire flock within days.
What Farmers Are Doing
Across the province, producers are tightening biosecurity protocols ahead of the seasonal surge. That means limiting flock access to the outdoors, securing feed and water sources to prevent contamination, and increasing monitoring for early signs of illness, lethargy, sudden drops in egg production, or unexplained deaths.
Industry groups have also been working with federal and provincial agricultural authorities to improve surveillance and response times. The Canadian Food Inspection Agency (CFIA) remains on alert, and farmers are encouraged to report any suspected cases immediately.
Biosecurity checklists, worker hygiene protocols, and equipment decontamination routines, once considered optional extras, are now standard practice for operations of all sizes.
A National Industry on Edge
While the current outbreak concern is centred in Alberta, the ripple effects of a bad avian flu season are felt coast to coast. Canada is one of the world's top poultry producers, and outbreaks affect everything from grocery store prices to export relationships. The 2022–2023 HPAI wave cost the Canadian industry hundreds of millions of dollars and led to the culling of millions of birds.
For consumers, recurring outbreaks can translate to tighter egg and chicken supplies, something Canadians have already experienced in recent years.
Looking Ahead
Veterinarians and agricultural scientists are cautiously optimistic that improved preparedness will blunt the worst impacts this season. But the fundamental challenge hasn't changed: wild birds don't respect property lines, and Canada's position along major flyways means the threat returns every spring.
For Alberta's farmers, the next few months will require vigilance, quick action, and a fair bit of hope that this migration season passes more quietly than the last.
