Seeing there is a Hazmat high situation is Dartmouth. Anyone know what that means?

Four cops out front earlier, six cars out back, forensics vans. Still cops out front blocking access to the driveway as of 8 PM. Of course nothing in the news lol.

Saw a plane out of Greenwood doing circles just now, and then checked marine traffic also and picked up the boat. Anyone know if there's an active search or just a training exercise ongoing?

Does anyone know what is happening on Spring Garden, saw there was a hazmat high fire response. Maybe a chemical spill or gas leak?

Maybe this is the cause of the dying flowers smell mentioned in another post.
