Question...does LSW need 4 tracks to hit max service? I'm curious whether there is width to extend OL west along the corridor before going underground to go up Jane for a possible west extension. Both would have surface station at Roncesvalles. Option 1 would go underground up South Kingsway, connect at Jane Line 2, then north. Option 2 would be underground up Parkside, connect at Keele Line 2, maybe a station at Dundas/Keele, then follow CP corridor undergrounds before turning north at Jane. Both options could include an intermodal station at Jane/Dundas/St. Clair west (call it Lambton, and have OL, Milton GO, St. Clair streetcar extension).
