In a statement, police did not mention the rally by name but said they were responding to “demonstrations” in the city.
“There have been no reported injuries, and police remain in full control of city streets,” police said in the statement.
More than 500 participants were expected to travel to Ottawa this weekend, according to event organizers.
Law enforcement officials have been bracing for protests.
Participants were warned by police that displaying symbols of hate like swastikas “will result in charges.” The agency also cautioned that “the targeting of any community events will result in a police and enforcement response.”
The city was paralyzed by the Freedom Convoy protests in January.
Eventually, the protests drew others who opposed coronavirus restrictions at the time.
Hundreds of vehicles formed convoys that converged on Ottawa, and many pedestrian protesters joined the vehicles. The demonstration clogged the downtown area as well as key routes between the US and Canada.
