An Air Canada Boeing 787-9, registration C-FNOG performing flight AC-25 from Vancouver,BC (Canada) to Shanghai Pudong (China) with 304 people on board, was enroute about 450nm southeast of Anchorage,AK (USA) when the crew received an EICAS message "FMC Verify Position" shortly followed by "NAV unable RNP". The crew consulted with dispatch and maintenance and decided to return to Vancouver, where the aircraft landed safely about 5 hours after departure.

A passenger reported the captain announced a complete failure of the GPS system.

A replacement Boeing 787-9 reached Shanghai with a delay of 8 hours.
