Something in the GTA stinks.

Newstalk 1010 callers say the smell of manure is filling their nostrils in places like Toronto, Hamilton, Oakville, Richmond Hill, Oshawa, Mississauga, Thornhill, Vaughan, Aurora & Brampton.

The smell seems to have moved in late Friday afternoon.

Newstalk 1010 has been unable to sniff out the cause of the stink.

The Weather Network says no major weather systems are to blame & the City of Toronto isn't aware of any sewer issues.

Don't blame the Holland Marsh for the stench either.  Ron VanHart, owner of VanHart Greenhouses in Kettleby, ON says they haven't used manure in the marsh in some 40 years.
