The Town of Mexico is located just 20 to 30 miles north of the growing metropolitan area of Syracuse, and is near an interchange of Interstate 81, a major north-south transportation artery. It is also within easy commuting distance of the smaller cities of Oswego and Fulton. Mexico is served by four New York State arterial highways that provide high speed transportation linkage to the surrounding area.

Accessibility to employment centers coupled with the town's rural environment and location within the scenic Lake Ontario shoreline region make it an attractive small town residential environment.

First formed into a town by an act of the New York State Legislature in April 1792. The Town included all of the present counties of Onondaga and Cortland and the western and central portions of Oswego County. The land commissioners were ordered by the Surveyor General to lay out and name each new town. Possibly one of the commissioners was interested in Central America, and chose Mexico for a name.

Mexico was an important stop for the Underground Railroad.  Starr Clark, among other residents of the town, was active in the abolitionist community.  He wrote the first antislavery petition Oswego County sent to Congress and his home and tin shop sheltered many people escaping slavery.  Most notably, in 1851, William "Jerry" Henry, a freedom seeker from Missouri who had lived in Syracuse, sought refuge here in Mexico while fleeing arrest under the 1850 Fugitive Slave Law.
