It is located in the province of Ontario and covers suburban areas north of Toronto. It was created in 2003 from the former Markham riding. The federal riding was first represented by John McCallum until he switched to the newly formed Markham—Thornhill riding for the 2015 election. Markham—Unionville was the only seat that the Liberals lost among those they held after the 2011 election, though the riding's boundaries changed considerably and would have been won by the Conservatives in 2011 based on the redistributed results.
54% of Markham—Unionville's territory (mostly south of Highway 407) was redistributed into the new Markham—Thornhill riding for the 2015 election. The area north of Highway 407 and west of McCowan Road remained in Markham—Unionville. The new Markham—Unionville riding also gained new territoryin the northwest corner of the city of Markham which were previously in the riding of Oak Ridges—Markham. 51% of the new riding came from Oak Ridges—Markham.
