Staying safe

With temperatures this low, everyone is at risk — including pets.

Officials are reminding folks to watch for cold-related symptoms such as shortness of breath, chest pain, muscle pain and weakness, numbness and/or colour change in fingers and toes.

Below are some tips courtesy of ECCC:

  • Dress warmly. Dress in layers that you can remove if you get too warm. The outer layer should be wind resistant.

  • Keep dry to stay warmer.

  • Cover up. Frostbite can develop within minutes on exposed skin, especially with wind chill.

  • Keep emergency supplies in your vehicle such as extra blankets and jumper cables.

  • If it’s too cold for you to stay outside, it’s too cold for your pet to stay outside.

  • Keep moving to maintain your body heat and seek shelter from the wind.

  • Outdoor workers should take regularly scheduled breaks to warm up.
