I second the vote for Mike Barry's work.
Around here there was(is) Bertrand - don't know much about their history or product (any of the other Ottawa CR listers fill in the blanks?)
In my home town of Kingston, Ontario there is a chap by the name of Geoff Brooks (an ex-pat Brit) who apparently is still building frames - Brooks Custom Bicycles. I knew Geoff in the late-70s early-80s - he built frames for a few of the local junior racers in town and if I remember rightly was commissioned to build the pursuit bikes for either the 1980 or 1984 Canadian Olympic team. I vaguely remember seeing one of his road bikes - lugged steel and quite nicely done. Geoff painted one of my frames for me - working out of a small, cramped, basement shop - still does! Any of you other Canucks know of Geoff's work?
