Sirmilik is home to diverse Arctic wildlife, including several marine mammal species such as narwhals, ringed seals, and beluga whales. The park's terrestrial mammals include polar bears, Arctic foxes, and caribou. Bird life is particularly abundant during the summer months, with notable species including snow geese, thick-billed murres, and black-legged kittiwakes. Bylot Island hosts one of the largest breeding colonies of greater snow geese in the world. The park's waters support various fish species, including Arctic char, while invertebrates form an important part of the local food web.
Despite the harsh Arctic environment, Sirmilik supports a variety of plant life adapted to extreme conditions. The park's vegetation includes hardy species such as Arctic willow, purple saxifrage, Arctic poppy, and various lichens and mosses. During the brief summer season, the tundra comes alive with colorful wildflowers. The park's plant communities are particularly diverse in sheltered valleys and lowland areas, where microhabitats provide protection from harsh winds. Many plants exhibit adaptations such as low growth forms and the ability to complete their life cycles in the short growing season.
The park's geology is characterized by dramatic glacial landscapes, including the Byam Martin Mountains and extensive ice fields. The park encompasses parts of the Lancaster Formation, featuring sedimentary rocks dating back to the Ordovician period. Notable geological features include deep fjords carved by glacial activity, extensive sea cliffs, and the remnants of ancient seabeds. The park's centerpiece, Bylot Island, is dominated by the Byam Martin Mountains, which rise to heights of 1,951 meters. Active glaciers continue to shape the landscape, while permafrost underlies much of the park's terrain.
Sirmilik, meaning 'place of glaciers' in Inuktitut, has been home to Inuit peoples for thousands of years. The area was traditionally used for hunting and fishing by the Inuit of nearby communities, particularly those from Pond Inlet. The park was established in 2001 after extensive consultation with local Inuit communities and is now co-managed by Parks Canada and the Inuit through the Nunavut Land Claims Agreement. Archaeological evidence suggests human habitation in the region dates back approximately 4,000 years, with sites containing remnants of both Dorset and Thule cultures.
Key attractions include the dramatic Navy Board Inlet, the extensive glaciers of Bylot Island, and the spectacular Borden Peninsula. The park's three separate units each offer unique landscapes: Bylot Island with its rugged mountains and glaciers, Oliver Sound with its deep fjords, and the Borden Peninsula with its dramatic cliffs and plateaus. The park is also known for its exceptional opportunities to observe Arctic wildlife, experience traditional Inuit culture, and witness natural phenomena such as the midnight sun and northern lights. The pristine wilderness and remote location offer visitors a rare chance to experience one of North America's most untouched Arctic environments.
Sirmilik National Park experiences a polar climate with long, severe winters and brief, cool summers. Winter temperatures typically range from -35°C to -15°C (-31°F to 5°F), while summer temperatures generally hover between -10°C and 10°C (14°F to 50°F). The park experiences 24-hour darkness during December and January, and 24-hour daylight from May to August. Precipitation is relatively low, with most falling as snow. Weather conditions can change rapidly, and visitors should be prepared for extreme conditions year-round, including sudden storms and strong winds.
