These are some webcameras showing lake ice in Nova Scotia and New Brunswick
Nova Scotia
links on novascotiawebcams are a bit slow
Windsor Lake Pisiquid NOTE The area shown (between the Hwy 1
bridge and the 101 causeway) is NOT the place to skate. It is always
open under the bridge, and a strong current weakens the ice through this
section. Skate on the other side of the bridge, from Falmouth boat
landing.
