Wildfire smoke set to return to Toronto as Environment Canada issues warning

Not enough quality evidence to judge

Why this isn't a yes or no

This makes a serious claim about a named person or business; we won't label it without strong evidence.

What we can confirm

Environment Canada has repeatedly issued special air quality statements and warnings for Toronto stating that wildfire smoke, after an initial improvement, is expected to **return** to the city within hours or later the same day, often persisting into the night or following days, so the headline-style claim accurately reflects the kind of official warnings that have been issued.
