A glitch in Google's new Street View images may lead online tourists to believe Toronto's tallest tower has a twin.

Peggy Mooney of Heritage Toronto, one of Street View's partners, said an error that shows two CN Towers side by side in Street View may result from an oversight in the way images are edited together.

Google could not be reached for an explanation this weekend, but a closer look at the panoramic photo shot at 52 Manitoba Dr. in Toronto also reveals a double image of the back of a streetcar, which suggests the two shots were not matched up properly.

The Google Maps feature launched in Canada Oct. 7 and displays images on the internet from a street-level perspective.

The service is now available in Toronto, Calgary, Montreal, Quebec City, Halifax, Vancouver, Squamish, B.C., Whistler, B.C., Ottawa, Kitchener, Ont., and Waterloo, Ont.

Google has been driving around and filming images of Canadian streets since 2007.
