Yes. Sometimes there is overlap between the provincial and federal jurisdiction when it comes to managing toxics. This is a case in which it would be better if there were a national standard, but not just for outdoor air. Indoor air quality is a big concern in Canada because we spend so much time indoors.
I know you've asked about your region, which is experiencing outdoor air pollution, but there's risk management for which we're still waiting for VOCs indoors in Canadian homes, for example. That's another dimension that has to be considered.
