The line proceeds northward above Don Mills to its final stop at the future Science Centre Station on the Eglinton Crosstown light rail transit line, now under construction. Metrolinx has altered its plans here, too, building the new Ontario Line station above the Crosstown station on the northeast corner of the Don Mills / Eglinton intersection, instead of the southwest.
This may end up being a complex transfer point for passengers, since the Crosstown station is underground and the Ontario Line stop is above-ground. One of the ironies of having Toronto transit planning constantly in flux is the fact that Science Centre Crosstown Station was built underground so passengers could easily connect with the future Relief-Line subway. Now that the Ontario Government has scrapped the underground Relief Line concept and replaced it with an elevated Ontario Line station here, the opportunity for easier transfers seems lost.
