Yes, IPA was a very full bodied well hopped man's beer!
No high school kids need apply!
I believe Labatt stopped bottling it in the late 1990's but an internet search indicates that it may still be found on draught in select taverns.
Incidentally, the Labatt's plant was a leisurely twenty minute walk from our house in the Wortley Road Village part of Old South London. My father worked there from 1952 or so until he retired in 1976 (although he always took the bus). I worked at Labatt's for four summers from 1972 to 1975 while enrolled at Western.
