TOREX is located too far out of the way for a growing number of collectors who do not (or can no longer) drive a car. In its current location by the airport, TOREX is not close to the TTC subway line and many people are not willing to spend hours travelling by bus to get to the venue.
That's me: I wouldn't drive out there to pay for parking & then to pay to go into see dealers wanting to sell you overpriced coins (& if you're lucky) banknotes. When I attended TO shows 20 years ago you could take the GO train into TO downtown (& walk) but that's no longer an option. There were only a few dealers who carried banknotes.
I can't imagine what the bus route would involve so I haven't even considered attending. Back then I could haggle re: the sales tax (but not any more). When I attend a show its usually to meet some fellow collectors (&/or buy supplies) since buying notes online is so much cheaper. I think that's essentially killing shows b/c they're mostly just about the bourse (& selling collectors coins/notes) which can be done so much cheaper online. They lack an education element like the RCNA workshops.
When I went to Torex 20 years ago there were the odd legendary paper dealer like Don Olmstead. These guys were friendly & would talk shop & teach us a few things (or 2). These days there's just coin dealers (& all the non-circulating coins, junk tokens, etc) who don't know how to grade a banknote if their life depended on it & have zero interest in what I'm interested in. Fortunately, there are more women involved but I think the old guard still dominate things (at their peril).
