yes, sorry, you are right. I've only ever gone as far as Pickering on Lakeshore East, and at Pickering they are wood. using streetview I can see concrete ties further east though.
GO always uses wood ties.
Concrete ties are cheaper and easier to obtain than timber and better able to carry higher axle-weights and sustain higher speeds. Their greater weight ensures improved retention of track geometry especially when installed with continuous-welded rail. Concrete ties have a longer service life and require less maintenance than timber due to their greater weight which helps them remain in the correct position longer. Concrete ties need to be installed on a well-prepared subgrade with an adequate depth on free-draining ballast to perform well.
