St. Laurent Boulevard (Ottawa Road #26) is an arterial road in Ottawa, Ontario, Canada. Beginning at the Royal Canadian Mounted Police college complex at Sandridge Road in the Manor Park neighbourhood, St. Laurent Boulevard runs in a straight line, slightly east of south, until it reaches Walkley Road. It then curves west and intersects with Conroy Road and Don Reid Drive. In Ottawa, the name of the street is pronounced exclusively in French, even among Anglophones, as it honours former Canadian Prime Minister Louis St. Laurent. Prior to urbanization, it was known as Hawthorne Road.
The northern part of the street, not yet a boulevard, skirts the residential Manor Park neighbourhood. South of Hemlock Road, it passes Beechwood Cemetery, one of the most important in the city, and also several high towers including the 30-story Le Parc building, which is the third tallest in the city.
The road becomes mostly commercial starting from McArthur Avenue up to Highway 417. At the corner of Coventry Road lies the St. Laurent Shopping Centre, one of the biggest malls in the city. OC Transpo's St. Laurent Station (the upper level) is located right beside the on ramp for Highway 417 westbound.
South of Highway 417 and Tremblay Road, the road becomes more industrial as it crosses a small industrial district to its east. OC Transpo's (Ottawa's transit company) main offices are located at the corner of Belfast Road, another key industrial road, which is also a link to the Via Rail's Ottawa station at its western end.
