Cool, I see some similar parts. Mine was originally also equipped with Campy pedals and seatpost. Also looks like the same 3TTT handlebar (Grand Prix Tour de France?), but clincher rims and tires.

FWIW, I've reached out to Brad Proctor via Facebook to ask if he would mind sharing the story of his frame-building years. He's currently retired in Sechelt B.C. but active with trail-building and may also be running a B&B. He had a bike shop in town called On The Edge, which appears to be gone although he still maintains a relationship with a similar shop called Off The Edge - perhaps the same shop with new owners.

I'd really like to establish if, when, and how many frames he built for the Olympic rider Curt Harnett, who is presently in Rio as Canada's chef de mission.
