Metrolinx has—I think for the first time—confirmed that there will be a Mount Dennis stop on the UP Express train. InsideToronto has a long article, well worth the read, that says, among other things, that
Anne Marie Aikins … confirmed plans for adding a Mount Dennis stop to UP which will require additional funding.
This is great news: the UPX will be that much closer to worthwhile public transit. The only problem: the fares, which will be announced next week, are expected to be more than $20.
The article contains few other details, but I think it’s safe to assume that the UPX would intersect with the new Eglinton LRT and/or the SmartTrack. Mount Dennis is shaping up to be a new transit hub.
