TORONTO -- A consortium including SNC-Lavalin (TSX:SNC) and Aecon (TSX:ARE) have closed a deal to build the Eglinton Crosstown light rail transit project in Toronto.

Under the project agreement, Crosslinx Transit Solutions, which also includes ACS Infrastructure Canada Inc. and EllisDon, will design, build and maintain the light rail transit line.

The line will span 19 kilometres, 10 of which will go underground, and include 25 stations and stops.

The Ontario government announced in 2010 it would spend $5.3 billion to build the project.

When the consortium was selected last month as the preferred bidder, it said it expected to start construction early next year.
