Madam Chair and committee members, it's a great pleasure to be here to share a little bit about Halifax and talk about what infrastructure funding means to our municipality.
Halifax is well known as the urban centre of Atlantic Canada. What people sometimes forget is that we're the largest rural municipality in Nova Scotia. In fact, if you look at a map, at the physical size of HRM, you could fit Montreal, London, St. John's, Quebec City, Winnipeg, Toronto, Edmonton, Calgary, and Hamilton inside the physical boundary of the region. Nobody knows that better than Sean Fraser, whose riding of Central Nova covers a lot of that area.
We're the centre of economic growth in Nova Scotia. We account for 10% of the land size, 46% of the population, but almost 60% of the GDP. That's important, because we have the complex needs of a growing urban centre but also the challenges and opportunities that come with a large rural community.
You've all heard the statistic that 60% of the infrastructure is the responsibility of municipalities, but we collect less than 10% of the taxes, so we have to be creative in order to reach our goals, and we need strong partnerships.
Halifax has been one of the fastest-growing cities in the country in the last number of years. You can see from the changing skyline the difference from 2014 to 2017 in how the city looks. We have ambitious goals. We have an economic growth strategy, which we started a couple of years ago, that sees us wanting to raise our population from 418,000 to 550,000 by 2031. We're making progress. We've grown by 8,000 and 7,000 in the last two years.
The most exciting statistic is that we're keeping and attracting young people here, sort of going against the trend of Atlantic Canada. Throughout the first nine years of the 2000s, we were losing people in that key demographic of 25 to 39, and now, dramatically, we're keeping them. We're rewriting the narrative of kids going down the road for opportunity.
We continue to open our doors to people from around the world, and the face of our city is changing dramatically. International immigration accounts for over half of our growth. I'm excited, pleased, and proud to say that our city welcomed over 1,000 Syrian refugees. That's my mayoral boasting.
On infrastructure specifically, public infrastructure is the foundation on which our communities are built, and infrastructure investment publicly spurs private investment. Building and maintaining local infrastructure—the roads, the bridges, the water systems—provides a clear and measurable return on investment. Predictable federal funding, as outlined in these bilateral agreements, will ensure that we and other communities, like that of my colleague from Dieppe, continue to achieve real, sustainable growth.
The most dynamic cities in the world have effective public transit systems. Modern and efficient public transit increases productivity, cuts gridlock, connects people, services, and businesses to one another, and improves the health of citizens. Public transit infrastructure allows us to better move people in and out and strengthens our transit options. For us, a big deal is commuter rail. It's an option being looked at by our regional council. If we can establish a commuter rail that's efficient and cost-effective, it will be an incredibly valuable asset for us and for the future of our city, working with partners like VIA and CN. We're also looking at bus rapid transit.
I also want to highlight water. Investment in water, waste water, and stormwater infrastructure is a national issue. These are systems that many of us take for granted. Upgrades to waste water are some of the most pressing and expensive needs for our municipality. We have some of the oldest pipes in Canada. We have a $2.6-billion integrated resource plan on water alone within HRM that we need to fulfill. Some of the pipes we've recently dug up in the city go back to 1856 and 1862.
Halifax is a coastal city. It's particularly vulnerable to the effects of climate change, especially sea level and storm surge. Those are absolutely critical investments. We're looking at innovative ways to combat climate change, including plans to incorporate district energy into major new projects in the city.
Private sector development comes after public sector investment. It's because of sound urban planning and big public investments that we have things in Halifax that are making a big difference.
Successful cities are built through strong partnerships between all orders of government and the private sector, and I look forward to continuing to work with you and my colleagues across the country as we build the cities of tomorrow.
Thank you, Madam Chair.
