Construction cranes dot the skylines of cities across Ontario, where colossal infrastructure and engineering projects prepare the province for future growth.

Several impressive Ontario megaprojects are due to cross the finish line in 2025, including major public works that will move people through cities, across international borders, and somehow, show off both the fastest and most brutally glacial construction speeds possible.

Here are the top five megaprojects expected to finish construction in 2025.

Eglinton Crosstown LRT

Now in its 14th year of construction, Toronto's Eglinton Crosstown LRT will surely finish construction in 2025 — something I tell myself in hopes of falling asleep but have little faith in at this point.

The perpetually problem-plagued line was all but complete this same time last year, and it seemed like an obvious shoo-in for our previous list of megaprojects that were due for completion in 2024.

I will be the first to admit that was an oopsie on my part, because here we are a year later with still virtually no idea when the route's first phase will finally open with 25 stations and stops along 19 kilometres of Eglinton Avenue.

In late November 2024, outgoing Metrolinx CEO Phil Verster hinted that an opening announcement could be forthcoming following the resolution of a software issue that had plagued the testing of the line.

Finch West LRT

The Finch West LRT was another Toronto transit project widely expected to enter service in 2024, and while there was indeed a somewhat vague announcement celebrating the completion of major construction works, riders still have no idea when the line will enter service for the TTC.

Similar to its costlier and higher-profile sibling line on Eglinton, construction of the 18-stop, 10.3-kilometre Finch West line is overdue and over budget, swelling from an initial cost of $2.5 billion to a current price tag of $3.4 billion

Luckily, Metrolinx's recent news that construction has wrapped offers some hope that the line will soon be moving riders along Finch Avenue West from Keele Street to Highway 27 — linking the TTC's Line 1 with Humber College.

Gordie Howe International Bridge 

The Gordie Howe International Bridge is a unique entry on this list in that it will not only be among the most significant megaprojects completed in Ontario this year, but also easily ranks among the top major projects in Michigan and the broader United States and Canada.

Supported by towers as tall as 40-storey buildings and spanning 2.5 kilometres between Detroit and Windsor, the new international border crossing claimed the title of the longest cable-stayed bridge span in North America in June 2024.

Construction is currently around ten months behind schedule, but the bridge is expected to welcome the first cross-border traffic in September 2025.

Rogers Stadium

A project that nobody had even heard of just a few months ago is suddenly in the running for one of the most anticipated buildings expected to come online next year.
Rogers Stadium is on tap to be the largest attraction of its kind in the city with a 50,000-person capacity.

The temporary facility is already under construction on 44 acres of land at the north end of the former runway adjacent to Downsview Park.

Live Nation

What is truly exciting about Rogers Stadium — and the reason for its inclusion on this list — is the ambitious construction window that would see the venue open in June 2025. 

Big names have already signed on to play at the new venue, including revived Britpop band Oasis, who are embarking on an international tour since the band's 2009 split.
 
And then, in a few years, it will all be torn down to make way for a new neighbourhood.

Confederation Line East Extension

Heading over to our nation's capital, another LRT project is expected to come online in 2025 with the planned completion of the 12-kilometre Confederation Line East Extension of Ottawa's O-Train system.

The extension is part of the broader $4.675 billion Ottawa LRT – Stage 2 project, and will bring service east from the existing Blair Station to a new terminal station at Trim Road in Orleans.

Once complete in mid-2025, the extension will serve commuters with five new stations built along a dedicated right-of-way in the centre median of Highway 174.
