Relief is certainly needed to ease congestion on the Bloor Line and particularly Y&B station, no question there. It will of course also offer far superior service to Toronto East and the burgeoning Waterfront/Portlands area. For me the issue is not the need but how it will be implemented.
I don't think standard 3rd rail TTC subways are the way to go and is shortsighted. They should use the same route but build it to accomodate RER catenary trains. It can still serve the exact same stations with the same capacity and frequency but it would allow other RER trains to use it so lines could be more easily interlined. It would relieve stress at Union which will quickly go over capacity and offer a vital alternative to Union in case of a problem at Union. Also a northern extension past Eglinton would be much easier and cheaper using RER trains as they could use the existing Richmond Hill GO route as opposed to having to build a totally new line from scratch if using standard TTC 3rd rail.
Bt using a RER tunnel you are effectively killing 2 birds with one stone for the same amount of money. RER could very easily overtake the subway in ridership in 30 years as is often the case with cities that have developed a RER system on top of a relatively small subway system and having 2 routes into the downtown core is a neccessity.

Once you have to build a tunnel all bets are off IMO, the cost is sky high that technology requirements are minor. Union station is already near capacity so feeding RER trains into it aren't wise (Originally 2nd downtown train station was planned for Wellington, it now looks like Spadina will get it). Also, using the current rail bed has been explored by the City and was not feasible.
Part of the rational to the DRL phase 1 is that you are chasing already established ridership points at Carlaw and future East Harbour site. Toronto needs to get past the pure spoke method of transportation planning as you have now mature areas that are built up with considerable growth in the near future that will benefit from rapid transit. These are the dense areas you build rapid transit for. Yes, in theory, using the current rail bed would make sense but where is space? With RER running every 10 minutes? There isn't much space left to run even more trains at 5 mins or fewer headways. RER is going to be well designed for what it is intended to do. If there is space then, of course, add in rapid transit and use the corridor but Toronto is tight for that flexibility.
There will have to be some sort of portal and crossing along the river to tread northwards but they don't know the exact point or the technology to make this happen as of yet which is part of the reason they have remained in the SE quadrant for this first phase. The eventual goal is to get this up Don Mills to Eglington and that is 100% part of the plan when they figure out how to do it. The Same issue is what cutoff the Eglinton Crosstown as they could not figure out how to continue the route westward while still feed and have access to the Yards at the old Kodak facility. The engineering challenge was great and the $$$ needed were skyhigh so they left it alone to revisit down the road.
