Earthquake

A sudden release of energy in the earth’s crust giving rise to seismic waves that can cause substantial damage, especially in urban environments.

Fire Alerts

Forest Fire

A wildfire or prescribed fire burning across a forested area, grassland or alpine tundra vegetation, and that poses a threat to people’s safety or property.

Industrial Fire

A large fire in an industrial building or complex that poses a threat to health or property.

Urban Fire

Major fire with the potential to cause large-scale damage to multiple commercial or residential properties.

Brush fire

A fire involving natural combustibles, especially grass, brush or trees, that may impact neighbouring communities.

Flood Alerts

Dam Overflow

An overflowing or failing of a dam or reservoir that threatens areas downstream. An alert is issued only in the case of imminent flooding.

Flash Flood

Sudden surge of water causing immediate flooding, often the result of rapid snowmelt, ice jams or heavy rain. A flash flood is a life-threatening danger, as there is little or no prior warning of such events.

Hazardous Materials Alerts

Biological Hazard

An organism or organism-derived substance that poses a threat to human health, and could easily be transmitted between organisms.

Chemical Hazard

A chemical substance that could, if misused or improperly released, result in psychological disorientation or serious injury such as disability or even death.

Explosive Hazard

Potentially hazardous substance or device that could produce an explosion, for instance through very rapid release of gases and heat.

Radiological Hazard

Potentially hazardous material in a concentration sufficient to harm the environment or human health.

Missing Person Alert

Amber Alert

An Amber alert is issued by the Sureté du Québec or the Service de Police de la Ville de Montréal when a child has been abducted, and it is believed their life is in grave danger. Amber alerts relay immediate and up-to-date information to the public and request their assistance in bringing about the safe and swift return of the child.

Storm Alert

Tornado

A tornado is a violently rotating column of air extending between a cloud base and the surface (when over water, it is called a waterspout). While often depicted as a funnel with the narrow end on the bottom, there is no typical tornado. Tornadoes exhibit a high degree of variability in their appearance, strength, speed, direction of movement, and duration.

It's Environment and Climate Change Canada (ECCC), which is responsible for issuing tornado alert for the province of Québec. When ECCC determines that there is an immediate or real threat to life or safety of persons, the tornado alert is automatically distributed on Québec En Alerte.

To learn more about the criterias for issuing a tornado alert by ECCC, please consult his website.

Public Service Alert

911 Service

This signals a 911 service disruption or outage.

This category covers all events other than those set out above that pose a specific threat to the safety or lives of people in Québec at a given moment.
