Maybe interesting, maybe nothing - Sheppard extension shown here to McCowan with no interchange indicated for Agincourt GO. I'd hope that the station at Sheppard/Kennedy has a convenient tunneled connection to Agincourt GO!

There are a few interesting other errors here though, i.e. the Milton line has an imaginary alignment which stays south of Bloor and doesn't connect to Bloor GO or Kipling GO, SSE looks like an extension of Line 5 rather than Line 2, no station icon for Kipling, etc..
