A weather advisory is an official notice from Environment and Climate Change Canada about current or expected conditions that may cause inconvenience or minor hazards. Unlike a warning, an advisory alerts you to less severe but still noteworthy weather, such as freezing drizzle, fog, or gusty winds. Check the live forecast above for any active advisories in your area.
What does a weather advisory mean?
A weather advisory signals that conditions could disrupt your daily routine but aren’t immediately dangerous. For example, a fog advisory reduces visibility to under 1 kilometre, while a freezing drizzle advisory makes untreated surfaces slippery. Advisories are common in southern Ontario and across the Prairies, including areas like Toronto and Calgary. Always treat an advisory as a heads-up, not a false alarm.
How is it different from a warning?
A warning means severe weather is imminent or occurring—such as a tornado warning in Ontario today—and demands immediate action. An advisory is less urgent but still worth planning around. For instance, a Canada weather hub check might show a weather advisory today for Calgary, suggesting slower commutes due to snow, whereas a warning would urge shelter. Advisories often precede warnings as conditions worsen.
Frequently asked questions
Should I change my plans for a weather advisory?
Yes, if the advisory affects your activity. A fog advisory means drive slower with low beams; a freezing drizzle advisory suggests delaying outdoor errands until pavement is treated. Check the advisory text for specifics.
How do I find a weather advisory near me?
Can a weather advisory become a warning?
Yes. For example, a freezing rain advisory in southern Ontario can escalate to an ice storm warning if precipitation intensifies. Monitor updates from Environment Canada, especially during events like a tornado warning in Ontario today.
