Ontario Premier Dalton McGuinty announced on April 1 that the government will provide $7.2 billion for transit projects in the greater Toronto area. The bulk of the money, $5.6 billion, is earmarked for three of seven transit lines that Toronto wants to build over the next 15 years. The longest and most expensive would be the $3.7-billion, 31-kilometer-long Eglinton Crosstown, connecting with Pearson International Airport. Construction is expected to start in 2010 and be completed by 2016. Approximately 13 km would be underground. The Ontario funding is not conditional on any matching grants from the city.
