The grey sky seems a bit more ominous out here.

With the winds whipping around and waves crashing on the break wall, Douglas Dobson walks around his home. His neighborhood sits on a narrow strip of land, with Lake Ontario to the north and several ponds to the south.


Gord Downie was more than the lead singer for The Tragically Hip, more than a Canadian rock icon.

As a deadline approaches for Lake Ontario flood victims to seek state aid, there are indications that the money may be stretched thin.

At the eastern end of the lake, about $1 million already has been committed to 45 homeowners in a three-county area, WRVO reports.
