The Foreign Office says it is “urgently working” with Canadian authorities to learn the identity of the victims of a plane crash in which six people died.

Some reports say four of those who died were British.

The Beaver seaplane took off on Sunday from Tadoussac, Quebec, on the north shore of the Gulf of Saint Lawrence.

It crashed shortly after in a wooded area in Les Bergeronnes. Investigators have been hindered by bad weather and the inaccessible nature of the terrain.

Tadoussac is located about 500km (310 miles) north-east of Montreal.

According to the AP news agency, police said on Monday that all six passengers aboard the Air Saguenay plane had been found.

Their bodies are reported to have been handed over to the coroner’s office.

A spokesman for the Foreign Office said: “Following a plane crash in Les Bergeronnes, Canada, we are urgently working with local authorities to establish the identity of those on board.”

Le Journal de Quebec newspaper named the pilot as Romain Desrosiers and one of the victims as Emilie Delaitre, a French woman visiting the country from the Cote d’Azur.

CBC News reports that the aircraft was built in 1956 but, according to Air Saguenay, had a “brand new” engine.

AP also reported that an Air Saguenay official said the seaplane was taking part in a routine sightseeing flight, which was only supposed to last 20 minutes.

The conditions were excellent at the time when the plane crashed on Sunday, the report added.
