Markham, Ontario

Markham is a city in York Region, Ontario, Canada. It is approximately 30 km northeast of Downtown Toronto. In the 2021 Census, Markham had a population of 338,503, which ranked it the largest in York Region, fourth largest in the Greater Toronto Area (GTA), and 16th largest in Canada.

The city gained its name from the first Lieutenant-Governor of Upper Canada, John Graves Simcoe (in office 1791–1796), who named the area after his friend, William Markham, the Archbishop of York from 1776 to 1807.

Indigenous people lived in the area of present-day Markham for thousands of years before Europeans arrived in the area. The first European settlement in Markham occurred when William Berczy, a German artist and developer, led a group of approximately sixty-four German families to North America. While they planned to settle in New York, disputes over finances and land tenure led Berczy to negotiate with Simcoe for 64,000 acre in what would later become Markham Township in 1794. Since the 1970s, Markham rapidly shifted from being an agricultural community to an industrialized municipality due to urban sprawl from neighbouring Toronto. Markham changed its status from town to city on July 1, 2012.

, tertiary industry mainly drives Markham. , "business services" employed the largest proportion of workers in Markham – nearly 22% of its labour force. The city also has over 1,000 technology and life-sciences companies, with IBM as the city's largest employer. Several multinational companies have their Canadian headquarters in Markham, including: Honda Canada, Hyundai, Advanced Micro Devices, Johnson & Johnson, General Motors, Avaya, IBM, Motorola, Oracle, Toshiba, Toyota Financial Services, Huawei, Honeywell, General Electric and Scholastic Canada.

History
Indigenous people lived in the area of present-day Markham since the end of the last Ice Age and the city is situated on the traditional territory of the Haudenosaunee (Iroquois), Huron Wendat, Petun and Neutral people. In the early 1600s, when explorers from France arrived, they encountered the Huron-Wendat First Nation. The southwest corner of Markham is included in Treaty 13, known as the Toronto Purchase of 1787, which transferred roughly 250,800 acres of land from the Mississauga people to the British Crown for 10 shillings and fishing rights on the Etobicoke river. The remainder of Markham's land (roughly east of Woodbine Avenue/Highway 404) is covered by the Johnson-Butler Purchase of 1787-88 (aka Gunshot Treaty) and formally by the Williams Treaties, signed in 1923.

Objects recovered by local mill-owners, the Milne family, in the 1870s give evidence of a village within the boundaries of the present Milne Conservation Area.

European settlement in Markham first began in 1794. The Lieutenant-Governor of Upper Canada, John Graves Simcoe (in office 1791–1796), named the township of Markham, north of the town of York (now Toronto), after his friend William Markham, then Archbishop of York. William Berczy first surveyed Markham as a township in 1793, and in 1794 led 75 German families (including the Ramers, Reesors, Wheters, Burkholders, Bunkers, Wicks and Lewis) from Upstate New York to an area of Markham now known as German Mills. Each family was granted 200 acre of land; however the lack of roads in the region led many to settle in York (present-day Toronto) and Niagara. German Mills later became a ghost town. Between 1803 and 1812 another attempt at settling the region was made. The largest group of settlers were Pennsylvania Dutch, most of them Mennonites. These highly skilled craftsmen and knowledgeable farmers settled the region and founded Reesorville, named after the Mennonite settler Joseph Reesor. In 1825 Reesorville was renamed to Markham and took the name of the unincorporated village (see Markham Village, Ontario).

By 1830, many Irish, Scottish and English families began immigrating to Upper Canada and settling in Markham. Markham's early years blended the rigours of the frontier with the development of agriculture-based industries. The township's many rivers and streams soon supported water-powered saws and gristmills and later wooden mills. With improved transportation routes, such as the construction of Yonge Street in the 1800s, along with the growing population, urbanization increased. In 1842 the township population had reached 5,698; 29,005 acre were under cultivation (second highest in the province), and the township had eleven gristmills and twenty-four sawmills.

In 1846 Smith's Canadian Gazetteer indicated a population of about 300, mostly Canadians, Pennsylvanian Dutch (actually Pennsylvania Deitsch or German), other Germans, Americans, Irish and a few from Britain. There were two churches with a third being built. There were tradesmen of various types, a grist mill, an oatmill mill, five stores, a distillery and a threshing-machine maker. There were eleven grist and twenty-four saw mills in the surrounding township. In 1850 the first form of structured municipal government formed in Markham.

By 1857 most of the township had been cleared of timber and was under cultivation. Villages like Thornhill, Unionville and Markham greatly expanded. In 1851 Markham Village "was a considerable village, containing between eight and nine hundred inhabitants, pleasantly situated on the Rouge River. It contains two grist mills ... a woollen factory, oatmeal mill, barley mill and distillery, foundry, two tanneries, brewery, etc., a temperance hall and four churches... ." In 1871, with a township population of 8,152, the Toronto and Nipissing Railway built the first rail line to Markham Village and Unionville, which is still used today by the GO Transit commuter services.

In 1971 Markham was incorporated as a town, as its population skyrocketed due to urban sprawl from Toronto. In 1976 Markham's population was approximately 56,000. Since that time, the population has more than quintupled, with explosive growth in new subdivisions. Much of Markham's farmland has disappeared, but some still remains north of Major Mackenzie Drive. Controversy over the development of the environmentally-sensitive Oak Ridges Moraine will likely curb development north of Major Mackenzie Drive and by Rouge National Urban Park east of Reesor Road between Major Mackenzie Drive to Steeles Avenue East to the south.

Since the 1980s Markham has been recognized as a suburb of Toronto. the city comprises six major communities: Berczy Village, Cornell, Markham Village, Milliken, Thornhill and Unionville. Many high-tech companies have established head offices in Markham, attracted by the relative abundance of land, low tax-rates and good transportation routes. Broadcom Canada, ATI Technologies (now known as AMD Graphics Product Group), IBM Canada, Motorola Canada, Honeywell Canada and many other well-known companies have chosen Markham as their home in Canada. The city has accordingly started branding itself as Canada's "High-Tech Capital". The province of Ontario has erected a historical plaque in front of the Markham Museum to commemorate the founding of Markham's role in Ontario's heritage.

Town council voted on May 29, 2012, to change Markham's legal designation from "town" to "city"; according to Councillor Alex Chiu, who introduced the motion, the change of designation merely reflects the fact that many people already think of Markham as a city. Some residents objected to the change because it will involve unknown costs without any demonstrated benefits. The designation officially took effect on July 1.

Geography
Markham covers 212.47 km2 and Markham's city centre is at 43.88333°N, -79.25°W. It is bounded by five municipalities; in the west is Vaughan with the boundary along Yonge Street between Steeles Avenue and Highway 7 and Richmond Hill with the boundary along Highway 7 from Yonge Street to Highway 404 and at Highway 404 from Highway 7 to 19th Avenue and Stouffville Road.

Recycling is collected weekly, while household trash and yard waste is collected every other week. The last week of May is "Bulk Collection", where residents can put out as much waste as needed without limits.

To promote recycling, Markham mandated the use of clear garbage bags in 2013 to let Miller Waste staff see the contents of trash bags. Bags containing high amounts of recycling mixed with regular trash will not be collected.

Economy
In the 19th century Markham had a vibrant, independent community with mills, distilleries and breweries around the intersection of Highway 7 and Markham Road. The Thomas Speight Wagon Works exported products (wagons, horsecars) around the world, and Markham had a reputation as being more active than York (the former name for Toronto) early on. Most of these industries disappeared leaving farming as the main source of business.

Light industries and businesses began to move into Markham in the 1980s attracted by land and lower taxes. Today, it claims to be "Canada's Hi-Tech Capital" with a number of key companies in the area, such as IBM, Motorola, Toshiba, Honeywell, Apple, Genesis Microchip, and is home to the head office of graphics card producer ATI Technologies (in 2006 merged with AMD). Over 1,100 technology and life science companies have offices in Markham, employing over one fifth of the total workforce. In 2014, the top five employers in the city in order were IBM Canada, the City of Markham, TD Waterhouse Inc., Markham Stouffville Hospital and AMD Technologies Inc.

International Franchise Inc., which owns brands including Swensen's and Yogen Früz and several others, has its headquarters in Markham.

General Motors Canada Canadian Technical Centre has been located in Markham since 2017, in the building which was formerly the Canadian head office of American Express from 1985 to 2015.

Performing arts
Markham is home to several locally oriented performing arts groups:
 * Kindred Spirits Orchestra
 * Markham Little Theatre

Markham's green space includes woodlots, ravines, and valleys that are not only enjoyable to its residents, but are important for the continued growth of the region's plants and animals. These natural spaces are the habitats for rare plant and insect species, offering food and homes essential for the survival of different native insects and birds.

Parks and pathways are maintained by the city's Operations Department.

East Asian businesses
Many shopping centres in Markham are also ethnically Chinese and East Asian-oriented. This is a reflection of Markham's large East Asian, particularly Chinese Canadian, population making it an important Chinese community in the GTA. They carry a wide variety of traditional Chinese products, apparel, and foods.

On Highway 7, between Woodbine and Warden Avenues, is First Markham Place, containing numerous shops and restaurants; this is several kilometres east of Richmond Hill's Chinese malls. Further east along Highway 7 is an older plaza is at the southwest quadrant with the intersection with Kennedy Road.

Pacific Mall is the most well-known Chinese mall in Markham, at Kennedy Road and Steeles Avenue East, which, combined with neighbouring Market Village (now closed) and Splendid China Mall, formed the second largest Chinese shopping area in North America, after the Golden Village in Richmond, British Columbia. In close proximity, at Steeles Avenue and Warden Avenue, there is the New Century Plaza mall and a half-block away there is a plaza of Chinese shops anchored by a T & T Supermarket.

There are also some smaller shopping centres in Markham, such as:


 * Albion Mall

Road network
Markham's road network is based on the concession system. In 1801, Markham was divided into 10 concessions, with a north–south road separating each one. The concessions were further divided by a number of east–west sideroads. This formed a grid plan road network, with an intersection occurring approximately every two kilometers. Even though some of these roads have been realigned, Markham's present road network for the most part still follows the original grid plan.

Markham's concession (north–south) arterial roads are listed below, ordered from west to east (former numbers in parentheses):


 * Yonge Street
 * Boundary with the City of Vaughan
 * Bayview Avenue
 * Leslie Street
 * Woodbine Avenue
 * Warden Avenue (5th Concession Road)
 * Kennedy Road (6th Concession Road)
 * McCowan Road (7th Concession Road)
 * Markham Road (8th Concession Road)
 * Continues as Highway 48 north of Major Mackenzie Drive
 * Ninth Line (9th Concession Road)
 * Donald Cousens Parkway / Markham By-pass
 * Signed as a regular road south of Box Grove By-pass
 * Reesor Road (10th Concession Road)
 * Eleventh Line (11th Concession Road)
 * York-Durham Line
 * Boundary with the City of Pickering

Reesor Road and Eleventh Line are the only north–south roads that are not fully regional roads. These two roads are rural routes with very few homes and minimal traffic. Eleventh Line ends just south of Highway 407 with the road rerouted (old section fenced off with partial gravel bed) to intersect with York-Durham Line. Areas east of Donald Cousens Boulevard either serve new residential developments or are largely rural and/or agricultural.

Markham's sideroad (east–west) arterials are listed below, ordered from south to north (former numbers in parentheses):


 * Steeles Avenue
 * Original Scarborough Townline, boundary with the City of Toronto
 * 14th Avenue
 * Continues west of Warden Avenue as Alden Road
 * Continues west of Rodick Road as Esna Park Drive
 * Continues west of Woodbine Avenue as John Street
 * Regional Road 7 (formerly 15th Avenue)
 * Continues as Highway 7 east of Reesor Road
 * 16th Avenue
 * Major Mackenzie Drive East (17th Avenue)
 * Elgin Mills Road East (18th Avenue)
 * Signed as a standard road east of Victoria Square Boulevard
 * 19th Avenue
 * Boundary with the Town of Whitchurch-Stouffville

Important thoroughfares
Major highways that pass through Markham include King's Highway 404 (from Toronto to just south of Lake Simcoe), which marks Markham's boundary with the City of Richmond Hill, and the 407 ETR (more commonly known as Highway 407), a privately owned toll highway that passes north of Toronto and connects Markham with Burlington and Oshawa. Highway 404 is one of the most important routes used for travel to and from the City of Toronto. Highway 407 primarily serves Markham from Yonge Street to York-Durham Line. The highway connects Markham with Clarington to the east, and Burlington to the west.

One of the most heavily travelled arterial roads in Markham is Regional Road 7, a major east–west artery. This road is more commonly referred to as Highway 7, a name which comes from the time when it used to be a provincial highway. The road is still officially Highway 7 east of Reesor Road. Other major east–west routes include 16th Avenue, Major MacKenzie Drive, the combination of John Street/Esna Park Drive/14th Avenue, and Steeles Avenue which forms Markham's southern boundary with Toronto.

Rail
The GO Transit Stouffville line, a commuter rail line stretching from Lincolnville to downtown Toronto, provides passenger rail service in Markham. It operates only at rush hour and uses tracks owned by Metrolinx, the provincial transit agency. Five stations on the Stouffville line serve Markham, of which 4 are within the municipal borders. In 2015, Metrolinx announced that the Stouffville Line would get an expansion in service, bringing all day both directional trains from Union Station to Unionville GO Station. Markham's section of this GO line also came under the spotlight in 2015 as City of Toronto Mayor John Tory's announced SMART Track plan for rapid transit expansion in Toronto includes the rail spur between Union Station and the Unionville GO.

On April 8, 2019, GO Transit added ten midday train trips to Mount Joy GO Station, replacing the need for passengers to change to buses at Unionville GO.

Public transit
York Region Transit (YRT) connects Markham with surrounding municipalities in York Region, and was created in 2001 from the merger of Markham Transit, Richmond Hill Transit, Newmarket Transit and Vaughan Transit. YRT to connects to the Toronto Transit Commission (TTC) subway system by way of Viva bus rapid transit from Finch station along Yonge Street, and Don Mills station through Unionville and on to Markville Mall.

YRT has two major terminals in Markham: Unionville GO Terminal and the new Cornell Terminal, replacing Markham Stouffville Hospital Bus Terminal.

The TTC also provides service in Markham on several north–south routes, such as Warden Avenue, Birchmount Road, McCowan Road and Markham Road. These routes charge riders a double fare if they are travelling across the Steeles border.

GO Transit provides train service on the old trackbed of the Toronto and Nipissing Railway, which connects Markham with downtown Toronto on the Stouffville commuter rail service. The line has stops at several stations in Markham, namely Unionville GO Station, Centennial GO Station, Markham GO Station, and Mount Joy GO Station. The Richmond Hill commuter rail line provides service to the Langstaff GO Station, which straddles Markham and Richmond Hill but is used primarily by residents of west-central Markham and southern Richmond Hill.
