[...] Also, I don't think anyone is 100% guaranteeing that Line 5 will run into capacity issues in the short term, but it doesn't take some leap of logic to think that Line 5 will capture lots of latent demand for a city so starved of rapid transit.
The demand projections for Line 5 were done off numbers from two decades ago when population growth rates were projected to be much lower [2]. To make matters worse, the advertised max 15,000 pphpd with 3 cars is unrealistic since it implies a >6 people m^2 crush load with 250 pax per 30 metre car and 0 flip up and multi-use seats used. A more realistic figure is 12,000 pphpd with 200 pax each for 3 cars, at 20 trains per hour.

For Line 5 Eglinton, we must distinguish between low absolute cost and high long-term value. Selecting a cheaper technology that provides disproportionately lower utility is a false economy, as it represents a poor value proposition if the marginal benefit fails to scale with the city's growth. In contrast, a subway (even a light metro) yields a significantly higher benefit to cost ratio because its superior potential throughput will far outweigh the incremental increase in construction costs. In hindsight, it's unclear Line 5 would've even cost more as a subway of any kind since the per km costs of Line 5 as mixed-grade tram are around 2 times that of the Vaughan Line 1 extension.

"The expansion of transit in the GTHA is the largest in North America today, but our job is far from over. By 2041, over 10 million people will live in our region— comparable to Paris or London."

2. In 2012 an updated case from Steer Davies Gleave was released. They predicted Eglinton would only need 9,000 pphpd by 2031 based on outdated population projections. (pg. 20/49)

In 2.4 (pg. 11/49) it says "The assumed employment and population forecasts used for the assessment are identified in ‘Places to Grow’ the Growth Plan for the Greater Golden Horseshoe area and is consistent with those used in the Regional Transportation Plan, The Big Move."
Places to Grow is from 2006. The Big Move is from 2008.

The Big Move says, "The GTHA, located in southern Ontario, is Canada’s largest urban region. It is also one of Canada’s fastest growing urban regions. With a current population of over six million people, it is forecast to be home to 8.6 million people by the year 2031."
Without fully accounting for undercounted visas and overstays, the GTHA population is already estimated to be 8.3 million as of July 1, 2024 (StatsCan). The true population of the GTHA could very well be 8.6 million already when factoring in NPR undercount as predicted by Benjamin Tal from CIBC (

The City of Toronto's official plan numbers they are citing for this forecast dates back to 2002 at least [2000, actually], before the
official 2001 census numbers were released, as part of

The city of Toronto has seen much more than a 270,000 increase in just the last 5 years, let alone since 2006.

IMO the problem is the P3 projects that proceed from ~50% design and rip off the taxpayers. Traditional procurement would probably get more built for the same budget. P3s blow through the budget, which leads to less projects being built, which leads to discontinuous construction etc... Not to mention Metrolinx is still grasping at straws about P3s apparently offering value for money when it clearly
does not in Ontario. IMO the lack of retained institutional knowledge at the government level is less of a problem because even in traditional procurement, the design stage is outsourced to an engineering firm.
