First of all, the Milton ROW will only support GO/CP 4 track corridor and no room for an elevated subway. CP will kill any idea of a tunnel under their corridor.Without advocating for or against, but to contribute here, I mapped out what I believe an MCC tunnel for the Milton GO line would look like in terms of placement and distance.
I would defer to those w/greater expertise than I, in saying I may not have it quite right.
I used only the simple assumptions that:
It must start and end at the existing Milton GO Line (assuming through service)
You want it as straight as possible, with gentle curves.

In the route layout above, I have bypassed Erindale station, one could choose to include that, but it either means a more southerly alignment (right along Burnamthorpe) , or a significant curve to the south at the western extent of the tunnel.
2. A 3 car subway train is overkill for ridership let alone 6 cars. You would be lucky to see 20 minute headway based on future ridership demand. Do the math to say what ridership may look like a 50,000 a day come 2050+ to justify quality of service.
3. Other than a Sq One Station, none of those stations come close in ridership to beat TTC Chester or Elsmere ridership numbers. You can't build higher density there now.
4. Any subway extension into Mississauga would be on Dundas as far as Dixie and only after Dundas has been redevelop to midrise mix development with 100-200,000 living and working along the route. Only after development takes place west of Dixie to Hurontario, the 2nd phase extension could be look at.
5. Far off having a tram-train using the Milton Line that will connect to the Hurontario Line at Cooksville GO Station with no station there for it. You could run the tram-train from Sq One and reconnect with the Milton Line on the north side of the 403.
6. Part of the Milton Line already has 3 tracks in place as well in operation. The whole Milton line was to be 3 tracks by 2007/11, but die. Until CP agrees to electrification, tram-train on the Milton Line is a dead issue at this time.
7. This extension is worse than the Yonge extension and way more costly..
8. Better off tunneling the GO Line to Sq One and then to the north side of the 403 using shorter trains.
