I'm being bombarded with their ads any time I watch youtube and the common theme seems to be cleaner air to reduce health costs.
Is there an issue with air quality anywhere in Alberta. Every time I check the air quality index Calgary is pegged at the lowest level (higher the worse the quality).
I can't find any historic charts. Is there any real issue with air quality at all?
Edit, found some
