The Calgary-Edmonton Corridor is the most urbanized region in the province and one of the densest in Canada. Measured from north to south, the region covers a distance of roughly 400 kilometres. In 2001, the population of the Calgary-Edmonton Corridor was 2.15 million (72% of Alberta's population). It is also one of the fastest growing regions in the country. A 2003 study by TD Bank Financial Group found the corridor is the only Canadian urban centre to amass a U.S level of wealth while maintaining a Canadian-style quality of life, offering universal health care benefits. The study found GDP per capita in the corridor was 10% above average U.S. metropolitan areas and 40% above other Canadian cities at that time.
According to the Fraser Institute, Alberta has very high levels of economic freedom. It is by far the most free economy in Canada, and is rated as the 2nd most free economy of U.S. states and Canadian provinces.

The Athabasca Oil Sands (sometimes known as the Athabasca Tar sands) have estimated non-conventional oil reserves approximately equal to the conventional oil reserves of the rest of the world, estimated to be . With the development of new extraction methods such as steam assisted gravity drainage (SAGD), which was developed in Alberta, bitumen and synthetic crude oil can be produced at costs close to those of conventional crude. Many companies employ both conventional strip mining and non-conventional in situ methods to extract the bitumen from the oil sands. With current technology and at current prices, about of bitumen are recoverable. Fort McMurray, one of Canada's fastest growing cities, has grown enormously in recent years because of the large corporations which have taken on the task of oil production. As of late 2006 there were over $100 billion in oil sands projects under construction or in the planning stages in northeastern Alberta.
Another factor determining the viability of oil extraction from the Tar Sands is the price of oil. The oil price increases since 2003 have made it more than profitable to extract this oil, which in the past would give little profit or even a loss.
With concerted effort and support from the provincial government, several high-tech industries have found their birth in Alberta, notably patents related to interactive liquid crystal display systems. With a growing economy, Alberta has several financial institutions dealing with civil and private funds.
Since the early 1940s, Alberta had supplied oil and gas to the rest of Canada and the United States. The Athabasca River region produces oil for internal and external use. The Athabasca Oil Sands contain the largest proven reserves of oil in the world outside Saudi Arabia. Natural gas has been found at several points, and in 1999, the production of natural gas liquids (ethane, propane, and butanes) totalled , valued at $2.27 billion. Alberta also provides 13% of all the natural gas used in the United States.
Notable gas reserves were discovered in the 1883 near Medicine Hat. The town of Medicine Hat began using gas for lighting the town, and suppling light and fuel for the people, and a number of industries using the gas for manufacturing. In fact a large glassworks was established at Redcliff. When Rudyard Kipling visited Medicine Hat he described it as the city "with all hell for a basement".
The coal industry was vital to the early development of several communities, especially those in the foothills and along deep river valleys where coal was close to the surface.
Alberta is still a major coal producer, every two weeks Alberta produces enough coal to fill the Sky Dome in Toronto. Much of that coal is burned in Alberta for electricity generation. Alberta uses over 25 million tonnes of coal annually to generate electricity. Alberta has vast coal resources and 70 per cent of Canada's coal reserves are located in Alberta. This amounts to 33.6 Gigatonnes.
Vast beds of coal are found extending for hundreds of miles, a short distance below the surface of the plains. The coal belongs to the Cretaceous beds, and while not so heavy as that of the Coal Measures in England is of excellent quality. In the valley of the Bow River, alongside the Canadian Pacific Railway, valuable beds of anthracite coal are still worked. The usual coal deposits of the are of bituminous or semi-bituminous coal. These are largely worked at Lethbridge in southern Alberta and Edmonton in the centre of the province. Many other parts of the province have pits for private use.
As of June 2007, Alberta's generating capacity was 11,919 MW, and Alberta has about of transmission lines.
Alberta has over 490 megawatts of wind power capacity. Alberta has added 4400 MW of new supply since 1998 – that's equal to all the power generated in Saskatchewan. Winter peak for power use in one day was in November 2006 – 9,661 MW. Summer peak for power use in one day was set on July 18, 2007 – 9,192 MW.
Building stones mined in Alberta include Rundle stone, and Paskapoo sandstone.
Diamonds were first found in Alberta in 1958, and many stones have been found since, although to date no large-scale mines have been developed..
In the past, cattle, horses, and sheep were reared in the southern prairie region on ranches or smaller holdings. Currently Alberta produces cattle valued at over $3.3 billion, as well as other livestock in lesser quantities. In this region irrigation is widely used. Wheat, accounting for almost half of the $2 billion agricultural economy, is supplemented by canola, barley, rye, sugar beets, and other mixed farming.
Agriculture has a significant position in the province's economy. Over three million cattle are residents of the province at one time or another, and Albertan beef has a healthy worldwide market. Nearly one half of all Canadian beef is produced in Alberta. Alberta is one of the prime producers of plains buffalo (bison) for the consumer market. Sheep for wool and mutton are also raised.
Wheat and canola are primary farm crops, with Alberta leading the provinces in spring wheat production, with other grains also prominent. Much of the farming is dryland farming, often with fallow seasons interspersed with cultivation. Continuous cropping (in which there is no fallow season) is gradually becoming a more common mode of production because of increased profits and a reduction of soil erosion. Across the province, the once common grain elevator is slowly being lost as rail lines are decreased and farmers now truck the grain to central points.
Alberta is the leading beekeeping province of Canada, with some beekeepers wintering hives indoors in specially designed barns in southern Alberta, then migrating north during the summer into the Peace River valley where the season is short but the working days are long for honeybees to produce honey from clover and fireweed. Hybrid canola also requires bee pollination, and some beekeepers service this need.
The vast northern forest reserves of softwood allow Alberta to produce large quantities of lumber, oriented strand board (OSB) and plywood, and several plants in northern Alberta supply North America and the Pacific Rim nations with bleached wood pulp and newsprint.
In 1999, lumber products from Alberta were valued at $4.1 billion of which 72% were exported around the world. Since forests cover approximately 59% of the province's land area, the government allows about to be harvested annually from the forests on public lands.
Edmonton is the headquarters of the only major Canadian banks west of Toronto: Canadian Western Bank, and ATB Financial.
