The Cinesphere at Ontario Place was open to the public for the Doors Open Toronto event, so this gave me a chance to revisit the structure. It had been many, many years since I'd been to Ontario Place, but it really hadn't changed that much. It is sad, though, to see the park neglected and unused as it was such a vibrant and happening place in years past. I also used the opportunity to discover a bit of the new Trillium Park just east of Ontario Place.
