Should we tell London to stop building Crossrail, because it is too close to other subway lines? And don't use the density excuse, because that is just that, an excuse.
The two lines will serve different travel purposes.

You're comparing apples and oranges.
For starters, most European cities didn't build RER-type lines from scratch. They were incremental improvements to existing lines, many of which were multi-tracked, grade-separated and electrified to begin with. Much of what we know of as the RER was basically differently-branded suburban service. All they had to do was add some ticketing machines and print some lines on a map and voila.
This is quite a bit different from SmartTrack, where you have to take a single track, diesel rail line built for occasional freight haulage with grade crossings and turn it into something resembling rapid transit.
Secondly, it's not the density of these European cities - it's how they have been oriented to transportation systems. Dense or not, Scarborough is completely car-oriented. You have 4 lane arterial roads with left turn lanes every 1 km on a grid and every commercial and residential unit comes with parking standards. Find me a European city that's built like that. Not only does it make transit difficult, it makes urban village-style densification around transit lines nearly impossible.
Finally, for most people in Scarborough, SCC is not a destination in itself, but a transfer point for buses originating in the north and east to the rapid transit system. In that sense, the "need" to serve SCC with heavy rail subway is not a given. You could just as easily have buses from north of the 401 transfer to SmartTrack at Agincourt station, or closer to Finch, and you could have buses from south of the 401 transfer to a mega-station at Kennedy (SmartTrack + subway + Eglinton Crosstown LRT + SCC LRT). The remaining service that needs to go to SCC because it needs to serve that area could easily be handled by LRT (the current RT handles less than the King streetcar).
I really think that two, parallel heavy rail systems - one of which is a bonafide subway traveling underground through the suburbs - is complete overkill for this area.
