Mount Royal, July 9, 2008 – During the summer of 2007, on the Island of Montreal, 13 days of extreme heat were recorded, when temperature rose above 30oC, including a five-day heat wave.

Oppressive heat is defined as air temperatures of or more than 30oC and a Humidex (temperature and humidity combined) of or more than 40oC.

Extreme heat is defined as:

  • Three consecutive days when the maximum temperature is at or above 33 oC during three consecutive days, and when the minimum temperature at night is at or above 20oC.
  • Two consecutive nights when the temperature is at or above 25oC.

Summer is at its midpoint and temperatures will most likely reach the high numbers again. Remember that exposure to extreme heat may cause dehydration, dizziness, discomfort, cramps, difficulty breathing, loss of consciousness, fatigue or exhaustion, chest pain, swelling of the legs or heat strokes.

Town of Mount Royal wishes to emphasize the recommendations from the Agence de la santé et des services sociaux de Montréal (Montréal Health and Social Services Agency), to reduce health problems in case of oppressive heat or extreme heat.

Recommendations:

  • Go to a cool place: Look for shaded or air-conditioned areas: malls, libraries, movie theatres, etc.
  • Drink plenty of water (unless contraindicated by your doctor). Don’t wait to feel thirsty before drinking.
  • Reduce physical activity.

Elderly persons and those with chronic illnesses, such as diabetes, cardiovascular, respiratory, kidney or neurological problems must be very careful, because extreme heat or heat waves may aggravate their health. Adults must be extra careful with children four years old and under, who can’t take the necessary precautions to protect themselves from the heat.

If symptoms related to heat exposure appear, contact Info-Santé at 8-1-1, or your doctor. In case of emergency, call 9-1-1.

If a heat wave should last more than three days, the urban agglomeration would put into action the Plan particulier d’intervention - Chaleur accablante ou chaleur extrême, and implement specific measures for the health and well-being of residents, such as opening air-conditioned shelters for at-risk persons.
