The Toronto Magnetic and Meteorological Observatory building from which the 1882 transit of Venus (ToV) was supposed to be observed survives, although it was moved to its present location subsequent to 1882. The observatory tower was built to house the high quality 152mm O.G. Thomas Cooke refractor commissioned for the ToV. The telescope also survives, and is in the collections of the Canada Science and Technology Museum in Ottawa.

The Toronto Magnetic and Meteorological Observatory was the nerve centre for the Dominion's Transit of Venus (ToV) campaign in 1882. That campaign was designed, organized, and directed by Charles Carpmael, the director of the observatory, superintendent of the Dominion's Meteorological Office, and first President of the reconstituted RASC from 1890-1894. The campaign involved thirteen observing stations, distributed from Charlottetown to Winnipeg.
