The Ottawa International Aiport (YOW) is 12km south of the downtown core and is Canada's sixth busiest airport. Because of Canada 150 celebrations throughout 2017, it will experience heavier volumes than usual. Plan accordingly. It serves many major North American airlines and has flights to Europe and several cities in the United States. However, most flights require a connecting flight through Toronto (YYZ) or Montréal (YUL).
The Ottawa Station (XDS), located at 200 Trembley Road, is served by Via Rail to Toronto and Montréal. Air France–KLM runs a connecting shuttle bus from this station to the Montréal Airport (YUL) as an alternate mode of transportation to/from Ottawa.
OC Transpo bus operates throughout Ottawa and parts of Gatineau. Fare is $3.40 CAD cash (coins) or two $1.70 CAD tickets.
A 25-30min, metered taxi ride to the Delta Ottawa City Centre by Marriott hotel from the airport will cost approximately $35CAD. Major credit cards are accepted onboard. Uber is available in Ottawa; a ride to the conference hotel from the airport will cost $19-25CAD.
The city of Ottawa sits within the St. Lawrence Lowlands ecoregion, characterized by warm summers and cold snowy winters, mixedwood forests of sugar maple, yellow birch, eastern hemlock, and eastern white pine. Average daily high/low temperatures in October are 15°C/3°C with a monthly average of 90mm of rain over 16 days.
