If Metrolinx would do what OC Transpo has done, and discuss with TC (now is a very good time, with the Fed Libs avid to get things moving) certifying options like the following, things can move ahead rapidly. And yes, it's more DMU's, albeit 'light' ones, not AAR/FRA crash compliant, but meet even more stringent APTA specs. If this is good enough for the US, surely than can be here too. Until electrification, which is still nebulous time-wise, an acquisition of these could buy Metrolinx time for the Weston Corridor/Bramalea South, and be cascaded to non-electrified branches when electrification occurs:
(These are proven and guaranteed, as are other European models assembled in North Am, Siemens and Bombardier et al)
[FORTH WORTH Transportation Authority signed a $US 106.7m contract with Stadler Rail for eight four-car articulated DMUs for the Tex Rail commuter line in a ceremony at the city's Intermodal Transportation Center (ITC) on June 9, 2015.
The contract, which includes the supply of components for 10 years, was signed by the authority's chairman Mr Scott Mahaffey, CEO Paul Ballard, and Stadler Rail CEO Mr Peter Spuhler. The deal includes an option for up to 24 additional trains and final assembly will take place in Texas with a site at nearby Lewisville being considered as a possible location for the facility.
The 43.5km 10-station line from Fort Worth city centre to Grapevine and Dallas Fort Worth (DFW) Airport Terminal B is due to open in late-2018 and is initially forecast to carry around 10,000 passengers per day, increasing to 14,500 by 2035.
On June 2 the US Federal Transit Administration gave Fort Worth Transportation Authority the go-ahead to take the $US 1bn project to the engineering phase, which included authorisation to order rolling stock.]

Here's an example of leasing in the UK, something I've suggested to howls of derision from one poster, but Metrolinx appears headed to disaster as per UPX. There are thousands of units for lease in the UK right now, many of them 'tapped out', many quite usable for a ten year lease or less:

[UK: Spanish rolling stock manufacturer CAF is to supply 281 new vehicles worth £490m for the next Northern franchise, leasing company Eversholt Rail announced on January 22.
The order comprises 31 three-car and 12 four-car electric multiple-units, and 25 two-car and 30 three-car diesel multiple-units. The 160 km/h units will be part of CAF’s Civity family, and all are scheduled to enter service by December 2018.
The new rolling stock will enable the fleet of 1980s Class 14x Pacer DMUs to be withdrawn from the Northern franchise, and potentially redeployed to other operators.

EMUs previously supplied by CAF are currently operated by Northern Rail and Heathrow Express, while Northern Ireland Railways has a fleet of DMUs and Midland Metro operates CAF trams. [...]
