Actually, both Lawrence and Ellesmere are good candidates for dedicated surface transit lanes, going from the eastern edge to SSE and then to Relief Line East. No major route hurdles, as far as I know. Ellesmere comes as BRT naturally, to be compatible with Durham Pulse. Lawrence East may be either BRT or light rail, either should work.
However if we want full Crosstown lines, things get tricky further west. Lawrence isn't continuous between Leslie and Bayview, and has a number of tight sections west of Yonge where adding 2 more lines would be difficult. In view of that, light rail may be more desirable for Lawrence E + W, as it will be easier to run through tunnels.
Ellesmere / York Mills / Wilson is continuous, but takes a very winding route over the hilly area around Yonge. Adding 2 more surface lanes seems out of question there, and even building a tunneled transit wouldn't be easy since the tunnel would need to clear both West Don river and the Yonge subway line that runs under the river. I recon, sections near Yonge will never get anything more advanced than mixed-traffic express bus service. Those express buses may use BRT lanes east of Bayview and west of Allen Rd, but will not form a full BRT.
