City closes outdoor sports facilities
The city shut down its outdoor sports facilities and two triathlons were cancelled, one in Montreal and one in Tremblant. As already noted, we’re the city with the worst air quality in the world this Sunday.
The fires are undoing years of efforts in restocking Quebec’s forests.

Although when I go to this air quality site that I prefer it seems Ottawa was even worse, this aft.

I have friends living outside Gatineau and they would agree.

Funny how Montreal got all the press today, even though Ottawa’s a G7 capital.
BTW if the smoke tracking map is right, Chicago looks to be very bad by Tuesday.

It’s hard finding decent Air Quality measurements. Environment Canada posts forecasts for Montreal but the “observed” is always “n/a”. (Qu-est que c’est le “n/a” en français? s/a ? a/p ? f/r ?) According to aqicn.org, Montreal max was 240 (high is bad), Ottawa was 358, Gatineau 142, Québec city 142, Cornwall (Ont) 234, Burlington (Vermont) 224, and Sult Ste-Marie 334 (!!!). When I was out tonight I could see the beams from car headlamps as if it was a foggy day even though the air looked clear.

@Mozai s/o for sans objet.

We’ve talked about this before here but it’s disappointing to see the failure of the Environment Canada website to provide realtime air quality data at a critical time. There’s lots of other options out there of course but in my mind EC was always the definitive source.
There are air quality stations across the province and I ASSUME it’s EC operating them, even if they can’t display the data on their website?

BTW someone else may have already shared this, but this map shows results at individual air quality stations across the city. You can just move the map around with the cursor to show your neighbourhood. I have no idea who’s paying for this and the site doesn’t seem to have ads but it’s a great example of what can be done. I presently live in Mile End so that is the focus here:

I just found it near the top of the results via Google. There’s been a lot of criticism of Google recently for the “enshittification” (coined by Cory Doctorow) of its search function but no complaints here.

I notice in the link that the two air quality monitoring stations displayed – including the one on Esplanade below Saint-Viateur – are both maintained by an “anonymous contributor.” Or maybe it’s two different people.

Purple Air and IQAir seem to be consumer products that let you monitor air quality and share it. If you scroll down to the bottom of the general Montreal page on that site you can see all of the data sources.

Ok. But the detailed data also includes forecasts that have to pulling and modelling data from other sources?
This reminds me a bit of the covid pandemic where suddenly it seemed like there were all these new resources online…

I don’t want to go on too long but this also reminds me of how EC animated weather maps only offer a glimpse of recent events – while that’s still very useful I have been going for some time to Meteomedia who offer a forecast map for projected weather, too.
I wonder how much of this is due to EC receiving a barebones parliamentary allocation.

What you are looking for is the Réseau de surveillance de la qualité de l’air and there are multiple groups doing it.
Here is city of Montreal data https://donnees.montreal.ca/dataset/?q=rsqa
Here is Quebec data ( which draws from city data too, I think) https://www.environnement.gouv.qc.ca/air/reseau-surveillance/Carte.asp

Thanks. Although looking at the second link, I don’t see the same monitoring stations? Like the one on Esplanade just below Saint-Viateur, which appears in the IQAir map, doesn’t seem to be there?

IQAir manufactures and sells air purifiers, etc. It provides the air quality website as a marketing tool, I would imagine. It takes data from government sources like those Kevin links to but also allows individuals who have their own sensor to provide them with data. The Esplanade station is anonymous but titled PurpleAir. PurpleAir manufactures air quality sensors, so this is likely somebody who has obtained a PurpleAir sensor.
PurpleAir has its own air quality map cum marketing tooI, so probably IQAir is getting that reading from them. It’s an open question how accurate those sensors should be judged to be versus what the city uses.

Thanks nau. Yes, I’ve been checking back and forth and so far the ‘PurpleAir’ IDed stations seem to be in sync with what other sites are reporting.

You could all save a lot of time and effort on this by just opening a window for a second and taking a whiff.
Kate 20:44 on 2023-06-27 Permalink
CE, true, but sometimes one just wants confirmation. The last two days I was like, ow, am I having eyestrain? or is it just the 200+ grit level in the air?!
