I don't know if your still looking, but if you are, give a stop into the front desk at Toronto Airways in Markham. (CYKZ) Last time I was there (mind you that was in August) there were adds posted in the lounge where the Wx Kiosk is for people looking to share time on a Mooney and a Aztec, (I can't speak for prices or A/C conditions, I never called for more info, was leaving town) There might have been a few others, I can't recall for certain.
I believe there may have been one or two private owners on South side of the field who were interested in doing the same (a twin commander comes to mind, but again I can't say for sure) . I would say you could ask one of my fellow ex-rampies, they might know if anyone is looking to sell shares or split time.
