There quite a number of Magdy's living in Canada. I am in Nova Scotia, many of my relatives are in Toronto and some more distant cousins are out west in Saskatchewan
My great-grandparents came from Kowalowka, Poland in what was then Galicia, an area which is now occupied by Poland and the Ukraine. The "y" in Magdy is an english translation of the "ij" in Magdij.
I got this info from the Hamburg Emmigration websit, the port from which the emmigrated from, this is a good spot to look.

I did not find any magdij on this site but did find a few on the Ellis Island Site http://www.ellisislandrecords.org/default.asp
