What is "dollard-des-ormeaux"

Dollard-des-Ormeaux (often referred to as D.D.O. or simply Dollard) is a predominantly English-speaking on-island suburb of Montreal in southwestern Quebec, Canada. The town was named after French martyr Adam Dollard des Ormeaux.

The town was merged with the city of Montreal for several years, but its residents elected to reinstate the city as a separate entity in 2006.

In 2001, the official Commission de toponymie du Québec ruled that the correct way to write the city's name was Dollard-Des Ormeaux (one hyphen, one space, all title caps). However, this was not widely accepted and is rarely used in practice. In particular, , the city's own website does not use this way of writing the city's name.
