I do remember that moving the tracks was a major topic when discussing this several years ago - tho I may be mistaken about the Clarence area requiring the tracks moved/removed.

The final report on the choice of alignments is available
here.
Page 59 indicates that both alignments were fine in terms of construction:

Discussions have taken place with CN regarding both the Concept 1 [dogleg] and Concept 2 [rail corridor] alignments. Although discussions were very productive and no show stoppers were noted, additional discussion and work will need to be undertaken

Page 63 indicates that the rail corridor option would have been slightly more expensive than the dogleg option ($313M versus $292M) due to the higher land acquisition costs. The actual construction costs would have been lower on the rail corridor route, though.
Also, they said there was no opportunity for grade separations on the rail corridor option, whereas the dogleg option did get us the overpass at McGillivray.
My "favourite" quote of all is on page 65:
Quote:
Concepts 1A and 1B [= the dogleg] are seen as being more suited to BRT while Concept 2 [=the rail corridor] is seen as being more suited to LRT

So despite all the talk about potentially converting the line to LRT in the future, they explicitly chose the alignment that is more suited to BRT. The suitability of the rail corridor alignment for LRT was actually treated as a negative rather than a positive.
