Another EU261 query

I can't see how EU261 would apply to a Canadian airline with a flight originating in Canada with delays in Canada.

"The regulation applies to any passenger:

• departing from an airport located in the territory of a Member State to which the Treaty applies;
• departing from an EU/EEA member state, or
• travelling to an EU/EEA member state on an airline based in an EU/EEA member state"
  
  

There is an ECJ ruling on the reverse, that states that a flight with connections that is booked as a single unit, on a single booking code, counts as a single flight. In this case it was Berlin —> Casablanca, Moroco and Casablanca, Morocco —> Agadir, Morocco. All on Royal Air Maroc booked as a single booking, not two singles. The first flight left late and she missed the second flight in Morocco

On those grounds, the Court (Eighth Chamber) hereby rules:

Article 3(1)(a) of Regulation (EC) No 261/2004 of the European Parliament and of the Council of 11 February 2004 establishing common rules on compensation and assistance to passengers in the event of denied boarding and of cancellation or long delay of flights, and repealing Regulation (EEC) No 295/91, must be interpreted as meaning that the regulation applies to a passenger transport effected under a single booking and comprising, between its departure from an airport situated in the territory of a Member State and its arrival at an airport situated in the territory of a third State, a scheduled stopover outside the European Union with a change of aircraft.
