finding (HFDF) network after the Royal Canadian Navy and the United States Navy agreed to coordinate and standardize their detection operations. The high cost of maintaining and supplying the base, however, led to it being shuttered in late summer 1952 and its equipment and personnel moved to Frobisher Bay (now Iqaluit) on Baffin Island. The site was eventually adapted as the Kuujjuaq Airport, which now includes a Nav Canada air-traffic control facility that relays information on flights in northern Canada to Montreal. With more Inuit settling in the area during this time to assist the base, a Catholic mission was established in 1948 and was followed by an infirmary, a school, and a weather station. The HBC outpost at Fort Chimo was closed for months of repairs in 1957 after a major fire, and the post was moved closer to the airfield in 1960. The remaining families who had still lived around the old site finally joined the larger community, establishing present-day Kuujjuaq (although it did not receive that name until 1980). The HBC store was sold to Hudson's Bay Northern Stores in 1987. Since 1996, police services in the Kativik region, including Kuujjuaq, are provided by the Kativik Regional Police Force (KRPF). The headquarters of the KRPF are located in Kuujjuaq. Geography Kuujjuaq lies upstream from Ungava Bay. Life in this community involves a close relationship with the river. Its tides regularly change the local landscape, while their rhythm strongly influences the traditional summer activities. Although the tree line is very close, the boreal forest is present around Kuujjuaq. Patches of black spruce and larch stand in marshy valleys. Kuujjuaq also witnesses annual migrations of the George River caribou herd. These animals pass through the region throughout August and September. Climate Kuujjuaq has a cold subarctic climate (Köppen Dfc), not far above the polar climate, but avoids that classification due to the temperate summers with daily mean temperatures of above . Winters are cold but by no means extreme for its latitude by Eastern Canadian standards. The cause of the extreme swings is the effect of the Hudson Bay to its west freezing in November. This eliminates maritime moderation from westerlies that are prevalent in moderating summer temperatures. With Hudson Bay effectively becoming a landmass during the winter, Kuujjuaq ends up being subject to severely cold winds. With the Labrador Current to its south-east also being cold, winter moderation
