FAQs about flying to Ottawa

Ottawa climate

Ottawa has a vast range of temperatures between summer and winter, and is subject to unpredictable weather conditions. Winters are generally snowy and icy. Temperatures in winter can drop as low as -25 degrees Celsius at night, but averages are misleading because days can be much warmer. Ice storms can occur. Summer weather in Ottawa is warm and humid, with temperatures exceeding 30 degrees fairly often, sometimes as early as April and as late as October. Summers are usually short, though, and spring and autumn are unpredictable, with early or late snowfalls possible or even unseasonal heat waves.

Getting around Ottawa

  • The Byward Market, east of downtown, is a huge neighbourhood, characterized by its open air market stalls. Fresh fruit, vegetables, flowers and art are all on sale in the stalls, while the surrounding shops have become increasingly boutique in recent years. Visit during the day for some shopping or browsing, or at night time for some of Ottawa’s best restaurants, bars and clubs.
  • For open air pursuits, the Rideau Canal is one of the best spots. Boat trips are available, for views of the city by water. These can usually be arranged at your hotel or at the canal. The banks of the river are popular routes for joggers and cyclists. Best of all, when the canal freezes over in the winter, it is transformed into a huge outdoor skating rink.
