A First Air Avions de Transport Regional ATR-42-300, registration C-GSRR performing flight 7F-5604 from Iqaluit,NU to Pagnirtung,NU (Canada), was enroute at FL190 when the crew inquired with Flight Information Service about the current weather at the destination, however, received the weather of Puvirnituq,QC (Canada) in error. The crew continued to Pagnirtung, however, during the descent received a ground proximity warning. The crew established contact with UNICOM at Pagnirtung about 20nm out, received the correct weather data and continued for a safe landing at Pagnirtung.

Canada's TSB reported Flight Information Service accidentally reported the weather data of CYPX (Puvirnituq) instead of CYXP (Pagnirtung), which provided a different altimeter setting. In the descent the crew received a terrain proximity warning. As there were VFR conditions there was no real risk of a collision with terrain. The crew received the correct altimeter settings from UNICOM Pagnirtung about 20nm out and continued for a safe landing.
