Option 2. Efficiencies and cost reductions need to be found. The extremely deep bored tunnel is unnecessary, and some of the stations seem overbuilt. I prefer a shallower tunnel, cut-and-cover under Slater Street, with a shallow bored tunnel from Elgin Street to the Rideau River. Also stations should be shortened to 125m each and private landowners should be responsible for building integration.

There should be six underground stations - Downtown West, Downtown Central (not in current plan), Downtown East, Mackenzie King, Campus and Lees. LeBreton could be covered as well to allow sheltered operation from LeBreton to Lees, which would be valuable in extremely bad weather (such as ice storms and blizzards) that paralyze the rest of the network.
