The real gun is called a SR-25, Echo 1 calls it whatever they want.
As for finding guns in Canada, if your over 18, you will need to meet with a local volunteer for this website to verrify that you are in fact 18+. Once your age verrified you will have access to this sites online classifieds. Thats really the only way to get an echo-1 in Canada.
Don't try to ship one in from outside of Canada, it will be stopped at the border.
It's better to light a candle, than to curse the darkness
