Gray Line Montreal, although a member of the Coach Canada family, is an independently managed operation,[1] that also formerly carried the brand of Stagecoach Montréal.

Autocar Connaiseur was founded in 1982 by Lorenzo Calce, a former vice-president of Murray Hill Limousines, operating charters and Gray Line sightseeing tours in Montreal.

In 1997 the company, which had grown to a fleet of over 100 buses, was sold to Coach USA[3] the North American division of Stagecoach.

Gray Line Montreal was included in the April 2019 disposal by Stagecoach of its North American operations to Variant Equity Advisors.

[6][7][8][9] In June 2024, Coach USA filed for Chapter 11 bankruptcy, blaming corporate impact caused by the COVID-19 pandemic.
