Province-by-province tick risks, prevention strategies, and what to do if you discover an attached tick.
For many Canadians, ticks were once considered a problem limited to a few isolated regions of the country. Today, that is no longer the case.
As temperatures warm and tick habitats expand, public health officials are reporting increasing numbers of Lyme disease and other tick-borne illnesses across Canada. The Public Health Agency of Canada has documented substantial growth in tick populations and human Lyme disease cases over the past decade, with risk areas expanding in multiple provinces.
For farmers, ranchers, and rural residents who spend significant time outdoors, understanding where ticks are found and how to protect against them has become an important part of staying healthy.
Why Tick-Borne Diseases Matter
Blacklegged ticks, commonly known as deer ticks, can carry bacteria, viruses, and parasites capable of causing Lyme disease, anaplasmosis, babesiosis, and Powassan virus disease. While not every tick carries disease, and not every bite results in illness, prompt prevention and removal remain the best defence.
Ticks can be found in:
- Woodlots
- Shelterbelts
- Creek banks
- Pastures near forests
- Tall grass
- Brushy fence lines
- Parks and gardens
Many Canadians are surprised to learn that ticks are no longer confined to remote wilderness areas and may be encountered in urban parks, suburban greenspaces, and farmyards.
Tick Risk Across Canada
Ontario
Ontario remains one of Canada's highest-risk provinces for Lyme disease. Established blacklegged tick populations are found throughout much of southern, eastern, and central Ontario, with tick habitat continuing to expand northward. Health authorities note that infected ticks may now be encountered almost anywhere in the province.
Quebec
Southern Quebec has experienced significant growth in tick populations, particularly in regions along the St. Lawrence Valley and near the U.S. border. Tick activity continues to move northward as environmental conditions become more favourable.
Atlantic Canada
Nova Scotia consistently reports some of the highest Lyme disease rates in Canada. New Brunswick and Prince Edward Island also have established blacklegged tick populations and public health officials encourage residents to use tick prevention measures whenever spending time outdoors.
Manitoba and Saskatchewan
Tick populations are now well established throughout parts of southern Manitoba and are expanding in southern Saskatchewan. Farmers working near wooded areas, shelterbelts, and riparian zones should remain vigilant throughout the growing season.
British Columbia
British Columbia is home to the western blacklegged tick. While Lyme disease infection rates tend to be lower than in eastern Canada, ticks carrying disease can still be found, particularly in coastal and southern areas of the province.
Alberta and Emerging Regions
Alberta remains a lower-risk province, but ticks are periodically introduced by migratory birds and wildlife. Public health agencies continue monitoring the spread of ticks into new areas.
How to Protect Yourself
Preventing tick bites remains the most effective way to reduce the risk of infection.
Experts recommend dressing appropriately for protection.
When working or walking in tick habitat:
- Wear long sleeves and long pants
- Use closed-toe footwear
- Choose light-coloured clothing to make ticks easier to spot
- Tuck pant legs into socks when walking through tall vegetation
These simple measures can make it harder for ticks to reach exposed skin.
Apply Repellent
Health authorities recommend insect repellents containing DEET or icaridin. These products can significantly reduce the likelihood of bites when used according to label directions.
Check Yourself Frequently
After outdoor work or recreation:
Inspect clothing and exposed skin
- Check behind knees and ears
- Examine the waistline and underarms
- Check children and pets
- Shower soon after returning indoors
Prompt detection can reduce the risk of disease transmission.
Reduce Tick Habitat Around the Farm
Property maintenance can help decrease tick numbers by:
- Keeping grass short
- Removing leaf litter
- Trimming brush near buildings
- Clearing vegetation from frequently used areas
These actions create less favourable environments for ticks.
What to Do If You Find a Tick
If you discover an attached tick, remove it as soon as possible.
Health Canada recommends:
- Use clean, fine-point tweezers.
- Grasp the tick as close to the skin as possible.
- Pull upward slowly and steadily.
- Avoid twisting or squeezing the tick.
Wash the bite area with soap and water or an alcohol-based sanitizer.
Do not attempt to remove a tick by burning it or covering it with petroleum jelly, nail polish, or essential oils, as these methods can increase the likelihood of infection.
Many Canadians now use the eTick identification platform to submit photographs of ticks and receive species identification information.
Know the Warning Signs
Symptoms of Lyme disease and other tick-borne illnesses can appear days or weeks after a bite.
Common symptoms include:
- Fever
- Chills
- Headache
- Fatigue
- Muscle aches
- Joint pain
- Swollen lymph nodes
- An expanding red rash, sometimes resembling a bull's-eye
Anyone who develops symptoms after a tick bite should consult a healthcare professional. Early treatment generally produces the best outcomes.
A Growing Farm Safety Issue
Ticks have become a reality for many Canadian farm families. While the risk varies by region, the message from public health officials is consistent: prevention, vigilance, and prompt tick removal remain the best tools for staying safe.
As tick populations continue expanding across Canada, making tick checks part of a daily outdoor routine may be as important as applying sunscreen or staying hydrated during the summer months.
