Passengers using a rail link to get to or from Ottawa’s international airport,
if such a link is ever built, would likely have to change trains at South Keys
station, residents learned this week at an open house showcasing the ambitious
plan to expand O-Train service. The city’s preferred option for extending the
north-south Trillium line from Greenboro station to Riverside South — for which
it is currently conducting an environmental assessment — includes a spur to the
Macdonald-Cartier International Airport and the EY Centre. via
