Gammage Flowers is Canada's oldest flower shop. Established in 1869 by James Gammage, the original store and greenhouses were located on what is now Gammage St in London On. James son Wallace took over and ran the flower business with his son Gard and for a while sons Fred and Walter helped too. Gard Gammage moved the flower shop to the Hotel London in 1936 and later moved it to an address on Dundas St that now occupies London's Central Library. The Gammage family sold the business in the 1970's to London businessman John McKerlie who in the early 1980's relocated the store to it's present location at the corner of Waterloo and Oxford streets. The present owner, Judite Holder, is only the fourth owner of Gammage Flowers, a flower shop that is rich in history and tradition.

The shop's present location is in a building with a long history in the City of London. Built in the 1880's,  this location once held a tavern that was frequented by the Black Donnellys. Later it was London's first Supertest Gas Station and over the years it has also housed a general store and The Drover Drug store. When you come into the store you can still see many of the original details including the original pine plank floors.
