[...] Right next door you can see the ROW narrows to 33 metres and even less closer to Yonge. And it's effectively narrower for reasons stated above.

In cases like these, the narrowest sections determine tram upgrade viability. There is no way the city fits a tram and four car lanes on Finch [closer to Yonge]. In a theoretical best case scenario you need only 20.6 metres curb-to-curb, and maybe 25-26 metres property line to property line, but in reality you more than likely need
at least 22-24 metres curb-to-curb and 30-32 metres property line to property line [to account for 4.2 metres for sidewalks, 3 metres for tram stop platforms and 1-2 metres conservative construction buffer for street widening and sidewalk reconstruction, assuming no grass boulevards, no bike lanes, no turning lanes at intersections like Line 6]
8 metres for tram ROW, 2x8 metres for car lanes in both directions with some buffer for ease of construction etc. and roughly 5 to 7 metres for sidewalks/boulevards. [...]
They are not going to build 2.1 metre wide sidewalks sandwiched exactly between the property line and the road surface to cram in a tram + four lanes of traffic in a cross section of 25 metres.
