As per tradition, the Gilmour Street Garage Sale falls on the Saturday after the long weekend. This year, it's Saturday, May 26th starting at 9 a.m.—although people have been known to show up as early as 7 a.m. in the hunt for a good bargain.
The biggest street sale in all of Peterborough, it extends out to many other streets in the neighbourhood, and there are also many sales for charitable organizations in town.
