Do climatic characteristics affect adaptation to Canada?

Climatic characteristics play an extremely important role in adapting to Canada, especially for newcomers from tropical and subtropical regions. This issue is particularly relevant in the context of global climate change, which makes adapting to the Canadian climate even more challenging for new immigrants and the country's healthcare system as a whole.

General impact of the Canadian climate on newcomers

Canada's climate zones and their impact

Canada is characterized by extremely diverse climatic conditions, which significantly complicates the adaptation of newcomers. The country has four distinct seasons, each with its own unique challenges:

• Winter (December-March): Temperatures can drop below -30°C in cities such as Winnipeg and Montreal, with heavy snowfall, black ice, and strong winds. Vancouver, on the other hand, has milder winters with lots of rain.
• Spring (March-May): Gradual warming, but cold spells are possible, with increased rainfall as the snow melts.
• Summer (June-August): In cities such as Toronto and Montreal, temperatures can exceed 30°C with high humidity, while in British Columbia the heat is dry and less intense.
• Fall (September-November): Cool air and bright fall colors, but temperatures can drop sharply.

Geographic differences in adaptation

Region	Winter conditions	Summer conditions	Main adaptation challenges
Toronto (Ontario)	Cold, snowy, down to -20°C	Hot, humid, 30°C+	Snowstorms, ice formation, humid heat
Vancouver (British Columbia)	Mild, rainy, rarely below 0°C	Warm, less humid, ~25°C	Constant rain, risk of flooding
Calgary (Alberta)	Severely cold, dry	Warm, dry heat	Chinook winds, sudden temperature changes
Halifax (Nova Scotia)	Maritime climate, windy	Cool summers, windy	Stormy conditions, high winds

Seasonal affective disorder and mental health

Prevalence of SAD among newcomers

Seasonal affective disorder (SAD) is a particular problem for newcomers to Canada. Studies show that 15% of Canadians experience mild forms of SAD, and about 2-3% experience severe forms.

Newcomers to Canada may be particularly susceptible to seasonal affective disorder due to:

• A combination of environmental, psychological, and social factors
• Lack of family support during the darkest months
• Changes in sunlight that disrupt the biological clock

Symptoms and signs

Emotional symptoms:

• Persistent sadness, irritability, feelings of hopelessness
• Loss of motivation and low mood

Physical symptoms:

• Fatigue, headaches, changes in appetite (especially cravings for carbohydrates)
• Weight gain, difficulty concentrating

Behavioral symptoms:

• Withdrawal from social activities
• Increased sleep duration, decreased interest in hobbies or work

Genetic factors of adaptation

Interestingly, studies show genetic adaptation to climatic conditions. Descendants of Icelandic immigrants in Canada have significantly lower rates of SAD compared to the population of the US East Coast, indicating genetic selection in the Icelandic population for adaptation to the long Arctic winter.

Physical challenges of adaptation

Winter challenges and safety

Clothing and insulation: Many newcomers do not know how to dress for Canadian weather, where to buy appropriate clothing, or cannot afford winter clothing. This poses serious health risks:

• Hypothermia and frostbite from prolonged exposure to cold
• Injuries from falls on ice due to improper footwear
• Respiratory problems from inhaling cold air

Three-layer clothing system:

1. Base layer: Moisture-wicking materials (synthetics, avoid cotton)
2. Middle layer: Insulating materials (wool, fleece)
3. Outer layer: Wind and moisture protection (waterproof jacket)

Transportation challenges

Winter driving:

• Winter tires are mandatory from October 1 to May 1 in some provinces
• Additional time is needed to clear snow and ice from the car
• Driving skills on slippery roads and in conditions of limited visibility

Public transportation:

• Bus delays due to weather conditions
• Longer waiting times at stops in cold weather

Extreme weather events and health

Impact of heat on health

Canada is warming twice as fast as the global average, creating new challenges for adaptation. Extreme heat can:

• Exacerbate existing health conditions, including cardiovascular and respiratory diseases
• Cause direct health impacts: dehydration, heat exhaustion, heat stroke
• Affect mental health, including depression and anxiety

Mortality statistics: In 26 Canadian cities for which the risk has been assessed, extreme heat increases the risk of mortality by an average of 2% to 13%.

Wildfires and air quality

2023 was the worst wildfire season in Canadian history, affecting every province and territory. This resulted in:

• Air quality issues across the country
• The evacuation of 192,000 people due to natural disasters exacerbated by climate change
• Additional stress on a healthcare system already struggling with the effects of the COVID-19 pandemic

Adaptation strategies and support

Individual coping strategies

For winter adaptation:

• Physical activity: Regular exercise, even indoors
• Light therapy: Use of light therapy lamps in the morning
• Vitamin D: Take supplements to compensate for reduced sunlight
• Social connections: Staying in touch with family and friends

For summer adaptation:

• Hydration: Maintaining adequate water intake
• Avoiding peak heat: Limiting outdoor activities between 12:00 p.m. and 4:00 p.m.
• Air conditioning: Use air conditioners or visit public cooling spaces

Systemic health support

Canada's National Adaptation Strategy includes a comprehensive approach to climate change adaptation:

1. Reducing the impact of climate disasters
2. Improving health and well-being
3. Protecting and restoring nature and biodiversity
4. Building and maintaining resilient infrastructure
5. Supporting the economy and workers

Special programs for newcomers

Educational initiatives:

• Winter preparedness programs for newcomers
• Information campaigns on safety in extreme weather conditions
• Training on the use of weather warning systems

Financial support:

• Winter clothing assistance programs
• Heating subsidies for low-income families
• Free mental health services

Long-term impacts of climate change

Future adaptation challenges

Projections for 2050:

• More than 140 million people could become internal climate migrants in sub-Saharan Africa, South Asia, and Latin America
• Canada could become a magnet for climate migrants due to its less extreme climate compared to many other countries

Changes in migration patterns:

• Internal migration in Canada could increase due to climate impacts
• Some regions may become uninhabitable, while others will remain less affected

Adaptation of the healthcare system

Current challenges:

• Half of Canada's healthcare facilities are over 50 years old and poorly equipped to deal with climate emergencies
• The healthcare system emits more greenhouse gases than aviation and shipping combined

Improvements needed:

• Modernization of healthcare facilities with cooling and air filtration systems
• Training medical personnel to work in extreme weather conditions
• Developing contingency plans for climate emergencies

Psychosocial aspects of climate adaptation

Trauma from climate events

Psychological consequences: Climate change creates additional levels of stress for migrants who already face the challenges of migration. This includes:

• Increased levels of anxiety, depression, and PTSD from exposure to traumatic experiences
• Uncertainty about future climate conditions
• Loss of control over life circumstances

Social isolation and community support

Risk factors:

• Lack of family support networks during difficult climatic periods
• Language barriers in accessing weather and safety information
• Economic constraints in accessing appropriate clothing and shelter

Protective factors:

• Resilience from previous traumatic events may help newcomers better adapt to climate challenges
• Community programs and support groups for newcomers
• Culturally sensitive mental health resources
