In all the years I spent in the GTA, (36) never saw them....
They are common in the city of Winnipeg....saw them predominantly when i was living there in the early 90's.
I love them...they don't disrupt my feeders....add to the joy....every now and then we get a black phased eastern grey up here....and to be candid, in the numbers we get, they're not disruptive either.....what is surprising though, is the reds take on and win, the greys.....
