Toronto city council is weighing the merits of two very different rapid transit options: the current plan for light rail transit (LRT) and an alternative subway extension plan recently proposed by Mayor Rob Ford. Which option will deliver more frequent, reliable and rapid transit - while keeping Toronto fiscally responsible? This report presents an analysis of these two transit options based on six important factors, including potential ridership, ability to serve regions of Toronto, cost and impact on traffic congestion. Toronto is in a fortunate position. Funding is available for the largest transit expansion in the Greater Toronto Area's (GTA) history. No matter which way the city proceeds, critical transit infrastructure needs to be built. However, with more than $8 billion at stake during the next 10 years, it is critical that Toronto gets the best value for its investment.
