I believe most of the rail crossings of the central corridor (and the lightly used corridor going west) can accommodate 2 tracks, with the exception of the Prince of Wales underpass and the Rideau River bridge. The former is likely to be replaced soon, and the latter would be quite expensive to reconstruct. That bridge would likely need 3 tracks if it is going to be used for commuter purposes as well.
Inside the Greenbelt, there are only three at-grade road crossings of the VIA track (plus a couple pedestrian crossings) - at Merivale, Pleasant Park and Michael Street. Pleasant Park would likely need to be closed to remove that crossing, since there is no reasonable grade separation possible, and Michael could probably be closed as well with traffic diverted to St. Laurent as traffic volumes likely don't warrant the cost. Pedestrian bridges could remain in those two locations though.
