In Toronto about 2,220 crosswalks have electronic signals that let visually impaired pedestrians know when they have the right-of-way. There are different sounds depending on the direction – a "chirp, chirp" sound indicates that pedestrians may cross east-west while "cuckoo" is the signal for north-south.
The Transportation of Canada (TAC) is recommending that the "chirp, chirp" signal be phased out because it sounds too much like a real bird. TAC is suggesting that it be replaced with a four-note tune known as the Canadian Melody. According to CBC News, Montreal and Halifax are switching to the new signal but as reported in the Toronto Star, Toronto has no plans as of yet to make the switch.
