There’s a new smog warning on the Environment Canada weather page: “Concentrations of fine particulate matter originating from forest fires will be high tonight and tomorrow. However, concentrations will be less significant than last Sunday’s smog episode.”
Thursday night was supposed to be the first show of the fireworks festival but the expected poor air quality means it’s been cancelled.
Now the festival is saying it will have to evaluate the state of the air before each show but that the whole festival could be cancelled.

I don’t see any links to it off yours but EC does offer animated smoke forecast maps, here: https://weather.gc.ca/firework/
“Canada’s Wildfire Smoke Prediction System (FireWork)”
No idea if its more, less or equally accurate as the https://firesmoke.ca/forecasts/current/

There’s a big red banner on the weather page from here – maybe it’s regional?

You mean the alert? Yes, but it doesn’t seem to direct one anywhere useful. In fact, amusingly, when you click on the link for http://www.canada.ca/info-smog-program you are directed to a page that has a “Most requested” with 3 links including “NAPS data products,” which got me curious. And it’s most requested! Well, if you click on it you get: “Server Error in ‘/’ Application. The resource cannot be found.”
I’ve said it before but the EC site is a mess. And I say this as a federal civil servant who has worked on the text and links for the new NFB institutional site.
Somebody there needs to clean this up.

It’s on Steven Guilbeault, the minister. Drop him a line?

And Kate, you were the one who pointed out a while back that if you click on Air Quality on the Montreal page you get “Observed Conditions: Not Available.”
It’s so bad that I wonder if it’s intentional, like, no to compete with private sector sites… I dunno.

I`m a little bummed they cancelled them, I`m quite the fan.
The firework shows must be pretty heavy air polluters. I wonder to what extent their pollution effect compares to the wildfire smoke.
