Cachet (Pronunciation: cash-AY) is a community within north-western Unionville, Ontario, Canada. It is bounded by 16th Avenue to the south, Major Mackenzie Drive East to the north, Warden Avenue to the east and Woodbine Avenue (or Highway 404, arguably), to the west.
The area is a residential development that has replaced farm land that once defined the town. The residents of Cachet consist mostly of middle to upper-income families and the housing consists of large single family homes. The Cachet Centre is a small strip mall that services mainly to local residents. There is also an Asian shopping centre that would be opened soon at the intersection of Woodbine Avenue and Markland Street, called King Square. When the shopping centre is completed, it would be considered as the largest Asian mall in North America. It is to be completed around 2020. The population of the community is predominantly people of Chinese and small minority of European heritage.
