The guidelines, key term, are not necessarily only for residential. But yes does focus on residential. The guidelines are not law, but can be used and enforced by municipalities if their policy is to follow the guidelines.

The guidelines are a bit arbitrary, as it uses 30m from the property line for main track operations. Secondary lines and such have different offsets. At the Forks, the property line is only a metre from the track. As opposed to a normal corridor where there is 15m from the track. Railside falls in line with the 30m setback. It also relies upon the fact that CN can not readily develop the lands the hold that are within the 30m setback. This is for the grassed areas near York, with the access roads leading up on top of the high line.

They also note you do not need to be 30m back if the building being proposed includes things such as crash walls.
