Situated on the western shore of Lake Ontario in the Regional Municipality of Peel, it borders Toronto (Etobicoke) to the east, Brampton to the north, Milton to the northwest, and Oakville to the southwest.

Another village with many longhouses was on the Antrex site, located on a wide ridge bounded by two small tributaries of Cooksville Creek.

[14] Around the end of the Woodland period, the Haudenosaunee, another Iroquoian confederacy, began to move into the area, and, as part of a long conflict known as the Beaver wars, they had dispersed the Wyandot by 1650.

[9] Mississauga's original villages (and some later incorporated towns) settled included Clarkson, Cooksville, Dixie, Erindale (called Springfield until 1890), Lakeview, Lorne Park, Port Credit, Sheridan, and Summerville.

Additional settlements were established, including: Barbertown, Britannia, Burnhamthorpe, Churchville, Derry West, Elmbank, Malton, Meadowvale (Village), Mount Charles, and Streetsville.

[21][22] Except for small villages and some gristmills and brickworks served by railway lines, most of present-day Mississauga was agricultural land, including fruit orchards, through much of the 19th and first half of the 20th century.

[23] The first prototypical suburban growth of Toronto Township began after World War II,[24] Applewood Acres was the first major planned development near the QEW and Dixie Road,[25] and urbanization soon rapidly expanded north and west.

To reflect the community's shift away from rural to urban, council desired conversion into a town, and in 1965 a call for public input on naming it received thousands of letters offering hundreds of different suggestions.

Port Credit and Streetsville remained separate, uninterested in ceding their autonomy or being taxed to the needs of a growing municipality.

[35] On 1 January 2010, Mississauga bought land from the Town of Milton and expanded its border by 400 acres (1.6 km2), to Highway 407, affecting 25 residents.

Some small streams and reservoirs are part of the Sixteen Mile Creek system in the far north-west corner of the city, but these drain toward the lake in neighbouring Milton and Oakville.

Apart from the embankments of Credit River valley, it tributaries and the Iroquois shoreline, the only noticeable hills in Mississauga are actually part of the former Britannia Landfill, now a golf course on Terry Fox Way.

[46] The climate of Mississauga is officially represented by Pearson International Airport but because of its topography and large surface area conditions can differ depending on location: fog tends to be more common along the Lakeshore and in the Credit River Valley at certain times of year, particularly during the spring and autumn.

[citation needed] During snowfalls when temperatures hover close to freezing, northern parts of the city, such as around Derry Road, including Pearson Airport away from warmer Lake Ontario usually get more snow that sticks to the ground because of the lower temperatures, often when rain transitions into snow or mixed precipitation.

The city usually experiences at least six months of snow-free weather; however, there is the odd occurrence where snow does fall either in October or May, none which sticks to the ground.

[citation needed] The Port Credit and Lakeview areas have a micro-climate more affected by the proximity of the open lake, warming winter temperatures as a result, but it can be sharply cooler on spring and summer afternoons, this can also be the case in Clarkson, but with much less consistency.

The Canada Day celebration was attended by 130,000 people in 2012, the Ribfest has recorded 120,000 visitors in 2012, and the inaugural New Year's Eve in 2011 has attracted 30,000 spectators.

A 12-station busway similar to Ottawa's Transitway was built parallel to Highway 403 from Winston Churchill Boulevard to Renforth Avenue, via the Mississauga City Centre Transit Terminal.

Rapid transit lines could possibly be built on some other main thoroughfares, namely Dundas Street and Lakeshore Road, but no definite dates have been set.
