How do I convince Yahoo that I'm in Toronto?

Yahoo keeps showing my location as Kitchener, and shows all the local news and weather about Kitchener. Now, I'm sure Kitchener's a great city, but since I'm in Toronto, I'm not much interested about the local news, weather or local businesses there.

My ISP's head office is in Kitchener, and thir ARIN whois entry lists that as their address for their IP addresses. They serve several cities but that's likely why Yahoo keeps showing my location as Kitchener, and all the localized news, weather, and everything else is for Kitchener.

I've already set my default location as Toronto, but Yahoo just ignores that. I'm not really sure what else I can do, short of switching ISPs for somebody that has their offices in Toronto.

Any ideas?
