Since 1956 when Ontario’s historical plaquing program was begun, more than 1,000 markers have been erected throughout the province.

The range of subjects commemorated is astonishing – from mining rushes in northern Ontario to the invention of the socket-head screw … from Harold Innis to Stephen Leacock … from the typhus epidemic of 1847 to the discovery of insulin. Popular culture is also well represented: "Beautiful Joe" commemorates an internationally successful novel about a dog; "When You and I Were Young, Maggie" celebrates a famous romantic ballad; "Jumbo" marks the spot where a beloved circus elephant died.

The history of Ontario, like its geography and its people, is vast and varied. Whenever you drive the highways, hike the countryside, or stroll through your own neighbourhood, this book can be a guide.

There is much to discover.
