Once a modest lumber town, Ottawa’s selection as Canada’s capital by Queen Victoria in 1857 was a decision that sparked controversy at the time. However, the city has since grown into the fourth-largest metropolis in the country, brimming with world-class museums, historic landmarks, and captivating national sites that showcase its rich history and cultural depth.
Positioned at the convergence of the Ottawa, Rideau, and Gatineau rivers, Ottawa enjoys a unique geographic setting that enhances its appeal. Visitors can explore significant government institutions, such as Parliament Hill and the Supreme Court of Canada, while also admiring its stunning architecture and charming cityscape.
The city is also home to expansive parks and green spaces, and the Rideau Canal, which runs through the heart of the capital, offers a variety of outdoor activities, including scenic boat cruises in the summer and ice skating in the winter.
