Yeah?
"Extreme cold warnings stretch across all three Prairie provinces as well as into northern Ontario with wind chill values between -40 and -45 and feeling closer to -60 in parts of northern Quebec.
"Conditions will moderate through the morning as daytime temperatures rise," says EC, adding that "extreme cold puts everyone at risk."
"Risks are greater for young children, older adults, people with chronic illnesses, people working or exercising outdoors, and those without proper shelter," warns EC. "Watch for cold related symptoms: shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes."
Dressing warmly and in layers is also recommended in such extreme conditions with the outer clothing layer recommended to be wind resistant.
"Synthetic and wool fabrics provide good insulation," EC says. "Cover up. Frostbite can develop within minutes on exposed skin, especially with wind chill."
