Toronto Montessori Schools

Thornlea Secondary School is a public high school, in the Regional Municipality of York, that opened in 1968 and is located in Thornhill, Ontario, Canada, on the northeast corner of Bayview Avenue and Willowbrook Road, just south of Highway 407. The school began in 1968 as an educational experiment. The curriculum was varied and specialized, following a trimester system, and students were encouraged to address their teachers by their first names and focus on independent learning. Around 1980 this model gave way to a more traditional academic environment.

Holy Cross Catholic Cemetery is a cemetery in Thornhill, Ontario, Canada. It is owned and operated by the Roman Catholic Archdiocese of Toronto.

Thornlea station was a station in Ontario, Canada served by CN commuter trains bound for Capreol/Parry Sound. The station was 16 miles north of Toronto Union. The station closed when CN's commuter services through the Bala Subdivision were discontinued. GO Transit's Richmond hill line operates services through the station's site but trains don't call at Thornlea station, instead calling at new stations in Old Cummer and Langstaff.

Langstaff GO Station is a train and bus station in the GO Transit network located in Richmond Hill, Ontario in Canada. It is a stop on the Richmond Hill line train service. In May 2005, construction of a new and more modern station building was completed, replacing the previous station building at Langstaff Road and using the north end of the same train platform. The south building was converted to a waiting room after the new station building opened for service on June 6, 2005. The new building has a ticket office for passengers to purchase bus and train tickets on weekday mornings. Langstaff Road East was the original routing of Highway 7 between Yonge Street and Bayview Avenue. When Highway 7 was upgraded, an overpass was constructed over the Canadian National Railway tracks, and the area north of Langstaff road became a large commuter parking lot. With the construction of Highway 407, the south lot was reduced in size, but newer developments north of the former Highway 7 led to the building of the new terminal. The south parking lot has a kiss and ride loop. The future extension of Line 1 of the Toronto subway will serve Langstaff GO station and the adjacent Richmond Hill Centre Terminal at Bridge station, with the extension expected to open in 2031.

Richmond Hill Centre Terminal is a York Region Transit, Viva, and GO Transit bus terminal in Richmond Hill, Ontario. Despite its name, the terminal is not located in downtown Richmond Hill, but is situated 4 km (2.5 miles) to the south at the city's southern limits, bordering Vaughan and Markham, near the connecting road that links the grade-separated Yonge Street and Highway 7 intersection. It opened on September 4, 2005. It is immediately west of the Langstaff GO train station, but is separated by the tracks. A pedestrian bridge over the tracks was opened in March 2008 to connect the bus terminal and the train station. Public washrooms were added to the terminal in December 2012.

York County is a historic county in Upper Canada, Canada West, and the Canadian province of Ontario. It was organized by the Upper Canada administration from the lands of the Toronto Purchase and others. Created in 1792, at its largest size, it encompassed the area that presently comprises the City of Toronto, the regional municipalities of Halton, Peel, and York as well as portions of Regional Municipality of Durham and the City of Hamilton. However by 1851, York County only consisted of the areas presently comprising Toronto and Regional Municipality of York. In 1953, York County was split again, with the area south of Steeles Avenue forming the Municipality of Metropolitan Toronto. York County was formally dissolved in 1971, with its remaining municipalities reorganized as the Regional Municipality of York.

Dollar is a former community of Markham Township, now the cities of Markham and Richmond Hill, Ontario, Canada and was located near the corner of 3rd Line and 15th Avenue (present-day Leslie Street and Highway 7). In 1869, Dollar was granted a post office, which was located on the north-west corner of Line 3 (Leslie Street) and 15th Avenue. In 1871 Dollar also had general store, a blacksmith shop and a church. The Zion Wesleyan Methodist Church was built about 1870 on Lot 10, Concession 3, on the east side of Third Line, just south of the intersection.With the arrival of the railroad through Markham Village and Unionville in the 1870s, the importance of smaller communities like Dollar began to fade. When rural mail delivery was instituted in 1914, Dollar was put on Rural Route #2, Gormley. In 1962 the name "Dollar" was rescinded and the hamlet ceased to exist. On January 1, 1971, the north side of Highway 7 was annexed to the-then Town of Richmond Hill. The last three historical homes were demolished in 1972 to prepare for the construction of the Best Western Parkway Hotel Toronto North. Today the former hamlet of Dollar is in close proximity to Highway 404. The site of the former post office is now the Times Square shopping centre. The City of|Markham is planning for significant future development on the south side of the intersection.

Langstaff is a residential area at the tripoint of the cities of Richmond Hill, Markham, and Vaughan in York Region, Ontario, Canada. Located near Highway 7 and Yonge Street, the homes in the area date to the 1960s and 1970s. The East Don River and CN Rail Bala subdivision runs through the area. Langstaff is a former hamlet likely named for John Langstaff (1774-1865), a settler who arrived sometime between 1803 and 1808 from Piscataway, Middlesex, New Jersey and established a farm along Yonge Street. The living members of the family are longer living in the area, as descendants of James Langstaff have moved out of Ontario. The old farm became the notorious Langstaff Jail Farm, which has since disappeared and the area is now dominated by a retail strip. The only reminder of the Langstaff family is Langstaff Road.

ATI Technologies Inc., commonly called ATI, was a Canadian semiconductor technology corporation based in Markham, Ontario, that specialized in the development of graphics processing units and chipsets. Founded in 1985, the company listed publicly in 1993 and was acquired by AMD in 2006. As a major fabrication-less or fabless semiconductor company, ATI conducted research and development in-house and outsourced the manufacturing and assembly of its products. With the decline and eventual bankruptcy of 3dfx in 2000, ATI and its chief rival Nvidia emerged as the two dominant players in the graphics processors industry, eventually forcing other manufacturers into niche roles. The acquisition of ATI in 2006 was important to AMD's strategic development of its Fusion generation of computer processors, which integrated general processing abilities with graphics processing functions within a chip. Since 2010, AMD's graphics processor products have ceased using the ATI brand name.

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.
