There are still a few public telephones kicking around! I added one a little while ago on 17th Ave SW. :)

That said, true enough they are becoming quite rare. Looking at Bing Streetside imagery dated 2019, you can see that the concrete pad at the northeast corner of the building where the phone would have once stood is now bare and empty. (https://www.bing.com/maps?cp=45.501534%7E-73.56102&lvl=19.4&pi=-1.8&style=x&dir=276.7) I have deleted this phone from the map, it's definitely long gone...
