Development
John Carling, Tory MP for London, gave three events to explain the development of London in a 1901 speech: the location of the court and administration in London in 1826, the arrival of the military garrison in 1838, and the arrival of the railway in 1853.
The population in 1846 was 3,500. Brick buildings included a jail and court house, and large barracks. London had a fire company, a theatre, a large Gothic church, nine other churches or chapels, and two market buildings. The buildings that were destroyed by fire in 1845 were mostly rebuilt by 1846. Connection with other communities was by road, using mainly stagecoaches that ran daily. A weekly newspaper was published and mail was received daily by the post office. Two villages named Petersville and Kensington once stood where downtown London now is. Petersville was founded by Samuel Peters in 1853. Kensington was founded around about 1878. Petersville and Kensington were amalgamated on March 4, 1881, to form London West.
On January 1, 1855, London was incorporated as a city (10,000 or more residents). In the 1860s, a sulphur spring was discovered at the forks of the Thames River while industrialists were drilling for oil. The springs became a popular destination for wealthy Ontarians, until the turn of the 20th century when a textile factory was built at the site, replacing the spa.
Records from 1869 indicate a population of about 18,000 served by three newspapers, churches of all major denominations and offices of all the major banks. Industries included several tanneries, oil refineries and foundries, four flour mills, the Labatt Brewing Company and the Carling brewery in addition to other manufacturing companies such as EMCO Wheaton. Both the Great Western and Grand Trunk railways had stops here. Several insurance companies also had offices in the city.
The Crystal Palace Barracks, an octagonal brick building with eight doors and forty-eight windows built in 1861, was used for events such as the Provincial Agricultural Fair of Canada West held in London that year. It was visited by Prince Arthur, Duke of Connaught and Strathearn; Governor-General John Young, 1st Baron Lisgar; and Prime Minister John A. Macdonald.
Long before the Royal Military College of Canada was established in 1876, there were proposals for military colleges in Canada. Staffed by British Regulars, adult male students underwent three-month-long military courses from 1865 at the School of Military Instruction in London. Established by Militia General Order in 1865, the school enabled Officers of Militia or Candidates for Commission or promotion in the Militia to learn Military duties, drill and discipline, to command a Company at Battalion Drill, to Drill a Company at Company Drill, the internal economy of a Company and the duties of a Company's Officer. The school was not retained at Confederation, in 1867.
In 1875, London's first iron bridge, the Blackfriars Street Bridge, was constructed. It replaced a succession of flood-failed wooden structures that had provided the city's only northern road crossing of the river. A rare example of a wrought iron bowstring arch through truss bridge, the Blackfriars remains open to pedestrian and bicycle traffic, though it was temporarily closed indefinitely to vehicular traffic due to various structural problems and was once again reopened to vehicular traffic December 1, 2018. The Blackfriars, amidst the river-distance between the Carling Brewery and the historic Tecumseh Park (including a major mill), linked London with its western suburb of Petersville, named for Squire Peters of Grosvenor Lodge. That community joined with the southern subdivision of Kensington in 1874, formally incorporating as the municipality of Petersville. Although it changed its name in 1880 to the more inclusive "London West", it remained a separate municipality until ratepayers voted for amalgamation with London in 1897, largely due to repeated flooding. The most serious flood was in July 1883, which resulted in serious loss of life and property devaluation. This area retains much original and attractively maintained 19th-century tradespeople's and workers' housing, including Georgian cottages as well as larger houses, and a distinct sense of place. In 1897, London West was annexed to London.
London's eastern suburb, London East, was (and remains) an industrial centre, which also incorporated in 1874. It was founded as Lilley's Corners by Charles Lilley in 1854. Oil was discovered in the Petrolia area and Lilley's Corners was chosen as the refining site because it was close to the railroad. The Ontario Car Works, the Great Western Gasworks and the London Street Railroad all had their headquarters in Lilley's Corners. In 1872, Lilley's Corners became a village. It was annexed to London in 1885. Attaining the status of town in 1881, it continued as a separate municipality until concerns over expensive waterworks and other fiscal problems led to amalgamation in 1885. The southern suburb of London, including Wortley Village, was collectively known as "London South". Never incorporated, the South was annexed to the city in 1890, although Wortley Village still retains a distinct sense of place. The area started to be settled in the 1860s. In 1880, Polk's Directory called London South "a charming suburb of the City of London.". By contrast, the settlement at Broughdale on the city's north end had a clear identity, adjoined the university, and was not annexed until 1961. Broughdale was named after Reverend Charles C. Brough, the Anglican Archdeacon of London who settled there in 1854. Broughdale started to grow when it was connected to the London Street Railroad in 1901, leading to a real estate bubble. A post office was opened in Broughdale on July 1, 1904, with Charles Watlers as postmaster. Broughdale was initially named Brough, but was renamed Broughdale in 1906 because it sounded better. In 1924, the University of Western Ontario was founded in the former Broughdale. After the founding of the university, Broughdale became more like a city and less like a village. Broughdale was incorporated as a village in 1930. In 1961, Broughdale was annexed to London.
Ivor F. Goodson and Ian R. Dowbiggin have explored the battle over vocational education in London, Ontario, in the 1900–1930 era. The London Technical and Commercial High School came under heavy attack from the city's social and business elite, which saw the school as a threat to the budget of the city's only academic high school, London Collegiate Institute.
The Banting House, a National Historic Site of Canada, is where Frederick Banting developed the ideas that led to the discovery of insulin. Banting lived and practiced in London for ten months, from July 1920 to May 1921. London is also the site of the Flame of Hope, which is intended to burn until a cure for diabetes is discovered.
London's role as a military centre continued into the 20th century during the two World Wars, serving as the administrative centre for the Western Ontario district. In 1905, the London Armoury was built and housed the First Hussars until 1975. A private investor purchased the historic site and built a new hotel (Delta London Armouries, 1988) in its place, preserving the shell of the historic building. In the 1950s, two reserve battalions amalgamated and became London and Oxford Rifles (3rd Battalion), The Royal Canadian Regiment. This unit continues to serve today as 4th Battalion, The Royal Canadian Regiment. The Regimental Headquarters of The Royal Canadian Regiment remains in London at Wolseley Barracks on Oxford Street. The barracks are home to the First Hussars militia regiment as well.
