The wikipedia articles (some I did not link directly) are all out there in the public eye. You dismissing something out of hand does not mean the evidence does not exist to condemn the relative slowness of the GO RER/GO Expansion project or the TTC's subway expansion. Sydney will likely have more subway than Toronto by 2032. Sydney is at ~51km to Toronto's 70km; Sydney will have 66km total by 2026 EOY and 89km by 2027 EOY. Their whole network only started construction in 2014. Much of the Sydney Metro system outside the downtown core is built more like fast commuter/regional express rail/express metro like what China has been pioneering with Guangzhou Line 18. Hence, Sydney Metro stop spacings are less than half of that of the TTC Subway. (

China's Pearl River Delta Metropolitan Region intercity railway covers a comparable area with comparable line length as GO. (
https://en.wikipedia.org/wiki/Pearl_River_Delta_Metropolitan_Region_intercity_railway). The GO Transit Rail network in its current length (not considering track ownership) has been around for 3 decades since the 1990s. The Pearl River Delta Metropolitan Region intercity railway has automated platform screen doors and only received approval to start construction in 2005. 20 years later, it is now larger than the core 5 line service area of GO Rail, at just under 500km (so not including the Milton and Richmond Hill lines and the LSW Hamilton-Niagara section), while providing subway-like peak frequencies under 5 minutes. And it's not like China doesn't have the occasional Line 5 Eglinton/6 Finch West style fiasco. Part of the Pearl River Delta Metropolitan Region intercity under construction is the Xinbaiguang section, it's been in limbo for 3-4 years. The line is basically complete, but due to purported bureaucratic issues among other issues (Metrolinx furiously taking notes), it has still not opened. When opened, the 78km section of the intercity network will directly connect Guangzhou's Airport to Shenzhen's Airport in 40 minutes for express trains. The Pearl River Delta intercity railway has not grown in completed length since 2021. (

GO Transit Rail is now looking like it will take 17 years from 2023 to 2040 (or even longer when you consider the construction projects done prior to 2023) to finish electrifying just the core portions of only Lakeshore West and East. That is insanity. 17 years to electrify just over 100km of rail from Burlington to Oshawa station. Compare that to the 113km long, fully automated, 0 level crossing, platform screen door having Sydney Metro which is fully on track to be done by 2032, 18 years from 2014, a project that was built with 1+2 piece-meal projects and not fully concurrently.
