The McLaughlin Planetarium is a former working planetarium whose building occupies a space immediately to the south of the Royal Ontario Museum in Toronto, at 100 Queen's Park. Founded by a grant from philanthropist Colonel R. Samuel McLaughlin, the facility was opened to the public on October 26, 1968. It had, for its time, a state-of-the-art electro-mechanical Zeiss planetarium projector that was used to project regular themed shows about the stars, planets, and cosmology for visitors. By the 1980s the planetarium's sound-system and domed ceiling were used to display dazzling music-themed laser-light shows. The lower levels of the planetarium contained a gallery called the "Astrocentre" that featured space-related exhibits, related artifacts on the history of astronomy and was also home of the world's first commercial Stellarium
