For the first time in Canadian history, the 100 largest public sector infrastructure projects under development have topped the $250 billion mark, according to ReNew Canada’s latest Top100 Projects report.

“Even in the wake of the COVID-19 pandemic, public sector infrastructure made significant progress in Canada in 2020,” said Andrew Macklin, author of the annual Top100 Projects report. “While work was slowed on some of these projects due to the pandemic, substantial strides were taken in both the procurement and construction of some of Canada’s largest infrastructure projects.”

The annual Top100 Projects report features the 100 largest public sector infrastructure projects currently under development in the country. Projects are ranked based on their confirmed project cost (capital or total contracts), and must be in active procurement, assessment, design and/or construction. The projects must also have funding support before being included in the report.

The value of the Top100 Projects rose from just over $240 billion in 2020 to just over $253 billion in 2021. The top five projects on the list remained unchanged from year-to-year: GO Expansion Projects – On Corridor, Bruce Power Refurbishment, Darlington Nuclear Refurbishment, Muskrat Falls Project, and the Eglinton Crosstown LRT.

In total, there are 16 new projects featured in the 2021 report, with the $10.9-billion Ontario Line (#6) being the largest new project added. Of the 16 projects that were removed from the 2020 report, 13 reached substantial completion, two are not moving forward, and one is no longer active.
