The effects of climate change pose risks to the health of Canadians and New Brunswickers.  As climate change increases, it is expected that extreme heat events will become more frequent even here in New Brunswick. Experience from around the world has shown that extreme heat events can have lethal consequences.  

People most vulnerable and at risk to health effects related to extreme heat are:

  • Young children and older adults,
  • The homeless and socially isolated,
  • People with chronic health conditions, and
  • People using certain medications.


HARS has three alert levels.  The levels are based on 3 factors that characterize an extreme heat event: intensity, duration and night-time exposure.

The Regional Public Health Offices monitor meteorological alerting provided by Environment and Climate Change Canada to determine when it is necessary to issue a Heat Alert.  The Regional Public Health Offices advise the public that conditions exist that could result in negative health effects.

The heat alert will be issued on the Department of Health twitter account @NBHealth.

 

Level 1

Heat Alert (Level 1) - Yellow

When a Heat Alert (Level 1) is issued, certain vulnerable persons may be affected.  The main cause of illness and death during a heat wave is the aggravation of pre-existing respiratory and cardiovascular diseases. 

Level 2

Heat Alert (Level 2) - Orange

When a High Heat Alert (Level 2) is called, everyone is at increased risk of heat stress and heat stroke under the conditions.

  • People living alone without air conditioning are at high risk especially if the heat wave lasts many days. 
  • Check regularly on your neighbours and relatives to make sure they are not in danger
  • Organizers of sport and recreational activities should build in regular water breaks and rest or consider rescheduling activities.  

Level 3

Heat Alert (Level 3) - Red

During an Extreme Heat Alert (Level 3) everyone is at high risk for heat related illnesses and heat stroke.

  • People living alone without air conditioning are at extreme risk.   
  • Check regularly on your neighbours and relatives to make sure they are not in danger.
  • Organizers of sport and recreational activities should reschedule activities.
