Torontonians can now take a “scroll” down memory lane, thanks to a free app showcasing years’ worth of scenes from Canada’s biggest city.

Launched this week, the Toronto in Time app allows users to view the city through a historical lens, using ‘then and now’ photos, slideshows and stories from more than 150 sites.

Virtual tourists can discover, for example, where soldiers of 1812 are buried, stand on the site of a 17th century First Nations village and learn stories about the Toronto club that hosted such celebrities as Marilyn Monroe, The Rolling Stones and U2.

The app also includes a cast of characters that played a role in creating the city’s history.

"Toronto in Time makes Toronto's history immediate and interactive," said Coun. Michael Thompson, Chair of the City's Economic Development Committee.

“It brings history alive and enables users to compare the place where they are standing with what it looked like decades ago."

Equipped with geolocation technology, users can discover sites marked on a map of Toronto, filter stories by theme or neighbourhood, and follow various walking trails.

Toronto in Time is the second of its kind, after a Vancouver version of the app launched in the fall of 2011.

It is available for download on iPhone and Android devices.
