Pedestrians and drivers in central Ottawa were met with a roar from the Hells Angels on Saturday afternoon.
Between 20 and 30 bikers formed a caravan that traveled down Bank and Rideau streets, described by police as an annual show of the organization's "presence" and "rights."
Ottawa police told CTV they were closely monitoring the procession.
The Hells Angels are currently believed to have 400-450 members scattered across Canada, including the capital region.
According to its official website, the Hells Angels Motorcycle Club first formed in the United States in 1948.
Since then, the Hells Angels have formed chapters around the world including Canada, Australia, South Africa, as well as in South America and Europe.
Two recent raids have returned the gang to the spotlight after Quebec's bloody biker wars of the 1990s.
Police arrested 156 people on April 15 as part of a major strike against the Quebec Hells Angels, with more than 1,200 officers taking part in a series of pre-dawn raids on properties across the province.
The S�ret� du Qu�bec said the raids targeted suspects who have allegedly been involved in crimes -- including various drug and gangsterism offenses, as well as 22 murders -- that took place between 1992 and 2009.
Police in Quebec and Ontario also carried out massive raids on suspected biker and street gang members in February in an attempt to disrupt cocaine-trafficking networks.
"Operation Axe" involved 700 police officers -- 500 from Montreal and 200 from Ottawa, the RCMP, and Laval and Longueuil police services.
Officers arrested 47 people in the raid, some of whom police alleged were Hells Angels members.
