With a population of just over 300,00, Markham is the fourth largest community in the GTA. Befitting its rapid growth, Markham, Ontario officially became a city in July 2012.

Markham started out in the 1800s as a center for brewing and distilling. Today, Markham calls itself “Canada’s Hi-Tech Capital.” IBM is Markham’s largest employer, while other Fortune 500 companies also base their Canadian operations out of Markham. These include Honda, American Express, Motorola and Honeywell.

Many of Markham’s smaller communities, such as Vinegar Hill, Mount Joy and Buttonville, retain much of their original 19th century charm. The annual Markham Fair celebrates the area’s rural beginnings, as do a number of historical museums and heritage sites.

Meanwhile, newcomers to the city, particularly South Asian and Chinese-Canadians, have added their distinctive traditions to the culture of Markham.

Along with its vibrant “little theatre” performing arts groups, Markham boasts many annual cultural, social and artistic festivals and events such as “Taste of Asia” and the Markham Jazz Festival.
