The city steadily grew during the 19th century, a major port of distribution as Upper Canada was settled. Toronto businesses grew including the meat packing business, leading to the nickname of "Hogtown". Toronto continued to grow by annexing outlying villages up until the early 1900s. After World War II, another major influx of immigrants came to the region, leading to a demand for new development in the outskirts of Toronto. To support the suburban growth, the Government of Ontario set up Metropolitan Toronto, a regional government encompassing Toronto and its suburbs, in 1954. The regional government, along with Ontario, invested heavily in infrastructure facilitating a boom in population and industry. In the second half of the 20th century, Toronto surpassed Montreal as Canada's largest city and became the economic capital of the country. In 1998, the "megacity" of Toronto was formed by the dissolution of the regional government and the amalgamation of the Toronto municipalities into one municipality.
