This year’s show will be held on Sunday, the 23rd of July 2023 at the The Latcham Centre at 121 Queen Street from 10am to 3pm, on the shores of Lake Scugog, next to the Marina.
Admission will be $4 and there will be parking along the nearby street.
Durham Region Transit provides access to the nearest bus stops at Simcoe and Queen (#3340 Northbound/#3339 Southbound), which are a 10 minute walk away from the venue, straight east down Queen.
This event is pretty much the only record fair, show or convention that I know of that will occur in July, although the Woodstock Toy & Collectibles Expo on Sunday, July 16th will feature music memorabilia and collectibles.
That event will occur at the Woodstock Fairgrounds at 875 Nellis St, in the Oxford Auditorium and Mutual/Market Buildings, from 9:30am to 2:30pm.
Early admission will be $10 from 9:30am to 10:30am, whilst regular admission will be $5 afterward and $3 from 1pm to 3:30pm. Admission will be free for kids under 12 when accompanied by an adult but note that cash is only accepted at this event.
Unfortunately, no conventional transit or para-transit is made available on Sundays in that city.
