Yonge Street has been listed in the Guinness Book of Records as the longest street in the world, although this claim depends on whether one considers Yonge Street to be synonymous with Ontario provincial highway 11.
In the thumbnail you can see the beggining (or the end, I don´t know that much) of the street. Follow the street to the north and watch where it finally ends.

it is know as yonge st about 5 minutes later when you hit the innisfil/barrie area..
however I agree that it isn't as long as they say. it's only about 90km from start to finish.
