The David Dunlap Observatory (DDO) is an astronomical observatory site in Richmond Hill, Ontario, Canada. Established in 1935, it was owned and operated by the University of Toronto until 2008. It was then acquired by the city of Richmond Hill, which provides a combination of heritage preservation, unique recreation opportunities and a celebration of the astronomical history of the site. Its primary instrument is a 74-inch (1.88 m) reflector telescope, at one time the second-largest telescope in the world, and still the largest in Canada. Several other telescopes are also located at the site, which formerly also included a small radio telescope. The scientific legacy of the David Dunlap Observatory continues in the Dunlap Institute for Astronomy & Astrophysics, a research institute at the University of Toronto established in 2008. The DDO is the site of a number of important scientific studies, including pioneering measurements of the distance to globular clusters, providing the first direct evidence that Cygnus X-1 was a black hole, and the discovery that Polaris was stabilizing and appeared to be "falling out" of the Cepheid variable category. Located on a hill, yet still relatively close to sea level at 730 feet (220 m) altitude, and now surrounded by urban settlement, its optical astronomy ability has been reduced as compared to other remote observatory sites around the world. On 31 July 2019, the DDO was accepted by the National Historic Board as a National Historic Site of Canada.

Richmond Hill United Church, at 10201 Yonge Street, is a designated heritage building in the town of Richmond Hill, Ontario, Canada. The main body of the building dates back to 1880, then as Richmond Hill Methodist Church, with later additions built in 1932 and in 1957 (Christian Education building). Originally the Methodist Church, it was renamed the United Church in 1925 when the Methodists, the Congregationalists, and the Presbyterians entered into a union. The church is, and always was, first and foremost a place of worship. In its early days there is a possibility that, aside from general church related uses, it could also have served as a Sunday school. With time and with the extensions the functions expanded in range. The church began to gain recognition not only as a religious venue but also as an important community marker. This church has a strong social justice orientation, and became an affirming ministry in June 2013. Currently, the church has tenants that use parts of its space, which include a dance school, a drama group, ESL training, and a math enrichment program. Occasionally the building is also used as a place for committee meetings and as a gathering space for community groups concerning cultural, social, or other issues.
