I think drums example is Eglinton to Cooksville requiring a transfer.
You are correct.
Eglinton and Hurontario area are to see major development for four sites with two other sites under construction to house somewhere 15,000 residents if not more since the plaza plan is not official for numbers yet, other than the nine towers ringing it that are official,
.
Pinnacle Uptownl site was originally to see 7,500 residents with the city cutting it in haft.
The plaza at Kingsbridge is to be redeveloped and that will add more residents to the area.
Today, Dundas see large numbers of riders using the 103 that it can be at crush load off peak let along at peak as they are going to work north of the 401, an area that still has a lot of empty employment lands as well to Derry Rd and Steeles.
The amount of ridership for the loop from M City and Parkside Village will be a drop in the bucket compared to new ridership on Hurontario.
The last time I looked at ridership numbers for Route 19, the south of MCC was at 60% and the North was at 40% and was moving toward a 50% split for riders who got off at MCC. It took 15 minutes to go to/from CCTT when traffic had no issues. When the line was split to route 17 and 2 as well adding Brampton 502 to the line, ridership fell close to 50% if not more for Route 17 that service was cut for it with the 103 picking up some route 17 ridership since it was saving riders close to 20 minutes of transferring time as well going to CCTT from Hurontario St on a good traffic timeframe, The 103 bus save riders 13 minutes bypassing CCTT each direction with a stop to allow riders to get to/from the mall or office buildings in the area.
When one looks at the whole corridor today, let alone 20 years down the road, the bulk of ridership will be from the north as far south as Dundas where it will start to drop off to the point very few riders will be going south of the Queensway to Port Credit. One reason that the 103 bus was cut back to the Queensway like it is today. Are LRV';s going to see the same thing???
Once Cooksville becomes an all-day service station for the Milton line, ridership will jump to/from it, especially from the north that riders for the line will drive to the station than try using the split LRT line and not have to waste their time doing so regardless transit is to be the better way.
