How Niagara’s Population Is Changing — And Why It Matters for Our Workforce

Niagara is growing — and not just a little. New data show that our population has increased by 20% over the past decade, with growth happening across almost every age group. That kind of change brings big opportunities, and equally big questions. Who is coming here? What does this mean for our local workforce? And how do we make sure Niagara is ready for the future we’re building?

Let’s take a closer look at what the latest numbers tell us.

A Growing Region — And a Changing One

Between 2014 and 2024, Niagara’s population rose from roughly 490,000 to more than 539,000 people. Growth is happening across all age groups, but the most striking increases are among older adults (65+) and people in their core working years.

This steady rise signals something important: Niagara is becoming a more attractive place to live, work, and build a life.

Migration Is Driving Much of Niagara’s Growth

One of the biggest stories in this year’s data is the role migration plays in shaping our region.

Net non-permanent residents (+60.8%) made the largest contribution to population growth.
Interprovincial migration (+41.5%) also played a major role, with many people moving to Niagara from other parts of Ontario.
Immigration added another 19.4% to the mix.

At the same time, we’re seeing declines in natural growth (births vs. deaths) — something happening across most regions in Canada. That makes migration even more essential to sustaining our workforce.

Men Slightly Outpace Women in Population Growth

Over the past decade:

Niagara’s male population grew by 21.5%
The female population grew by 17.9%

These aren’t massive differences, but they do help us understand shifting demographics in our communities.

And they raise a question worth asking: How do we ensure that everyone — across gender, age, identity and experience — feels supported and included in Niagara’s changing workforce?

Young Working-Age Adults Are Leading Net Migration

The age group driving the largest net migration to Niagara?
People aged 25–44.

This matters for a few reasons:

These are often people in the heart of their careers.
Many are raising young families or entering stages of life where long-term stability really matters.
They’re essential to helping Niagara fill job vacancies and strengthen our labour market.

If Niagara wants to remain competitive, ensuring housing, transportation, and childcare are accessible to this group becomes a major priority.

Thorold’s Population Growth Stands Out

Every municipality in Niagara has grown over the past 10 years — but Thorold’s growth is remarkable, nearly doubling (+46.6%).

Municipalities like Fort Erie, Lincoln, and Grimsby also saw strong increases. These trends reflect ongoing shifts in where people choose to live, commute, and work, and they highlight the need for region-wide planning that supports sustainable growth.

Why This Matters for Niagara’s Workforce

Population change isn’t just a numbers story — it’s a people story. And for Niagara, these changes signal real opportunities.

Here’s what stands out:

Migration is sustaining our workforce as natural population growth declines.
Younger workers are choosing Niagara, giving employers a chance to tap into fresh talent.
Growth varies across municipalities, meaning local planning needs to reflect local realities.
Diversity in age and background is increasing, giving us the chance to build a more inclusive and future-ready economy.
