The "Ioco" hillclimb, as it was known many years ago was run on the "front side" of the hill by the Royal City Sports Car club back in the mid '70's. Then, when BCMA got together they gradually took over the running of Ioco. It stopped running for a few years in the 90's and then made a brief comeback, using the back side of the hill. It has been quite a few years since it last ran. I believe the excuse is ownership and liability. The property belongs to an oil refining comany who don't want any chance of accident liability. Too bad, I've run both sides of the hill and it was fun to drive. Short, but fun.
Hillclimb's in B.C. come under the auspices of CACC Time Attack, previously know as Solosport. You should contact the new director of the Time Attack discipline to ask if anything can be done to resurrect this, or other hillclimbs. A few years ago the CACC Solosport director made an attempt to organize a hillclimb at Hemlock Mountain in the Fraser Valley. It failed, although there may still be some legs if someone wants to pick up the torch. Also, about 7 or 8 years ago there was an attempt to organize a hillclimb at Bamberton on Vancouver Island, which also failed.
So that leaves Knox Mtn., still the best hillclimb in Canada and still THE test of your skill to record a good time.
Good luck with your endeavour.
