Important! Non-US citizens should avoid flights that transfer in the US (even if they are cheaper). Citizens of most countries require a US visa to do this. Citizens of all countries have to pass through immigration and customs twice: once in the US and once in Canada. There is thus an increased risk of missed connections and lost baggage.
All visitors are now required to secure an Electronic Travel Authorization (eTA) or visa before travelling. Read more here.
If you need a letter of support for your visa application, please email the conference organisers on <cascaiuaes2017(at)nomadit.co.uk> informing us of this need along with your intended travel dates. (If there is necessary information we don't already hold, we will ask for that.) We will then issue you with a signed, headed PDF from the conference convenor at University of Ottawa to present to the Canadian authorities.
There is a direct flight from London-Heathrow on Air Canada to Ottawa, but most people will fly to Toronto or Montreal and catch a connecting flight there. There are also various shuttle services from Montreal Airport to Ottawa; note that KLM, Swiss & Air France passengers have a special bus which runs to Ottawa in accordance with the flights of those airlines. Buses leave from Pier 7 at the airport.
It is also possible to fly to Montreal and take the Greyhound bus to Ottawa, which has the advantage that the bus can drop you off directly at the University of Ottawa.
