Munro criticized certain aspects of the drlnow proposal, but not the part about tunneling a couple of km under the Lakeshore line.
Personally I can't see why anyone would bother talking about DRL as a HRT subway on anything like a Pape to Dundas W routing. The alternative is a full upgrade of GO service between Kennedy, Union, and Pearson. This would cost something like:
- electrification: <$1 billion
- 10 GO-style infill stations: <$300 million
- pedestrian tunnels to TTC at Danforth and Bloor GO: $20 million?
- fare integration (i.e. free transfers to TTC from GO, FOREVER): $600 million
That's, what, 40 km of rapid transit for $2 billion, in place of <7 km you could buy with subway tunnels.
(Note I didn't include any cost for track work on the Georgetown corridor, or improvements at Union, because the solution there is free: kill the ARL! But I guess something should be counted for an extra track or two on the Lakeshore E line to make this work.)
