No, you haven't stumbled into some post-apocalyptic version of Toronto.

Hundreds of the "un-dead" will be shuffling their way through the streets of downtown Saturday afternoon as part of Toronto's 10th annual Zombie Walk.

People in gory, bloody makeup & dressed in ripped clothes have been gathering at Nathan Phillips Square since noon.

At 3pm they'll start a "5 Kill-O-meter" stroll .  They'll head west on Queen St to University Ave, then north to Dundas St & east to Yonge.

Organizers say after "infecting the masses" at Yonge & Dundas Square, the zombies will head south to Queen & back to "Nathan Phillips Scare"

The party there continues into tonight with vendors & lives music.
