The Ottawa-Gatineau metropolitan area, often referred to as Canada's National Capital Region, represents a unique urban tapestry spanning two provinces, Ontario and Quebec. Its population dynamics are influenced by various factors, including migration, economic opportunities, and historical growth patterns. Understanding the current population figures and their underlying trends provides crucial insights into the region's socio-economic fabric and future trajectory.
As of 2025, the estimated metro area population of Ottawa-Gatineau is approximately 1,466,000. This figure represents a steady increase from previous years, showcasing the region's continued growth trajectory. For context, in 2024, the population was 1,452,000, and in 2023, it was 1,437,000, indicating a consistent annual growth rate of around 0.96% to 1.04% in recent years.
It's important to distinguish between the population of the City of Ottawa and the broader Ottawa-Gatineau Census Metropolitan Area (CMA). While the City of Ottawa itself had a population of 1,017,449 in the 2021 Census, the CMA, which includes Gatineau and surrounding municipalities, was 1,488,307. This larger metropolitan area is the primary focus when discussing the combined population of the National Capital Region.

The Ottawa-Gatineau CMA has experienced significant demographic shifts over the past few decades. The 2021 Census data revealed a population of 1,488,307 for the CMA, marking an 8.5% increase from the 2016 population of 1,371,576. This growth rate was notably higher than the national average of 5.2% and Ontario's 5.8%, positioning Ottawa-Gatineau as the fourth-largest metropolitan area in Canada in 2021, regaining its spot from Calgary.
Looking further back, the CMA grew by 25% between 1996 and 2013, adding nearly 260,000 residents. While growth rates fluctuated, with a peak of 2.1% in 2001, the overall trend has been positive. Projections suggest the CMA's population will continue to expand, potentially reaching 1.5 million by 2025 and even larger figures by the end of the century.
These figures highlight that the Ottawa-Gatineau region, particularly the City of Ottawa, has been a strong magnet for population growth within Canada.
Beyond raw numbers, the demographic composition of Ottawa-Gatineau reflects its unique cultural and social landscape. As a federal capital, it attracts people from across Canada and around the world, contributing to its rich diversity.
The bilingual nature of the Ottawa-Gatineau region is one of its defining features. According to the 2021 Census, 37.2% of the population within the Ottawa-Gatineau CMA reported knowing both English and French. While Ottawa city proper has a higher proportion of English-only speakers, Gatineau's population is predominantly French-speaking, contributing to the overall high bilingualism of the National Capital Region. Additionally, 20.4% of the CMA's population reported a mother tongue other than English or French, with significant proportions speaking Arabic (3.2%), Chinese (3.0%), and Spanish (1.2%).
In terms of ethnic diversity, Ottawa-Gatineau has a substantial foreign-born population, accounting for 21.4% of the CMA's residents in 2021 (313,845 people). The region also boasts the third-largest Black and Arab populations in Canada, according to 2021 census data.
The 2021 Census reported over 38,000 Indigenous residents in the Ottawa-Gatineau region, with 26,395 living in Ottawa and 11,705 in Gatineau. While Gatineau has a higher proportion of Indigenous residents (4.1%) compared to Ottawa (2.6%), both cities are below the national average of 5.0%.
Future population projections for Ottawa-Gatineau indicate continued growth, albeit with some anticipated shifts in age composition. While annual population growth is expected to moderate slightly in the coming years (projected to fall to 0.9% by the mid-2020s and 0.5% by 2041), the overall population size will increase.
A significant trend projected for the region is the aging of its population. The 65 and older age groups are expected to grow faster than the CMA average between 2013 and 2041, with this segment potentially adding over 213,000 residents and raising their share of the total population from 13% to 24%. This demographic shift will have implications for urban planning, healthcare, and social services.
