Establishment of the Park

It is Canada’s 37th national park and was established in 1996. The word wapusk comes from the Cree word for “white bear” / “polar bear”. 

The park encompasses 11,475 square kilometres (4,430 sq mi). The purpose for its conservation is to protect a representative sample of the features and wildlife of the Hudson and James Bay lowlands. 

The park becomes the home of the Western Hudson Bay polar bear population and is one of the largest maternity denning areas for pregnant polar bears. The spring is an active time as new polar bear families emerge and other bears comes to the shoreline as the ice melts from Hudson Bay. 

There are no roads or trails leading into the park so the limited number of visitors gain access by tundra vehicles like buggies or upgraded vans. 



Wapusk National Park is located in the Hudson James Lowlands, which is a unique transitional region between Manitoba’s boreal forests and Nunavut’s treeless Arctic tundra. 

Hudson Bay is such a large body of water that it creates its own frigid microclimate. The tide is so strong here that there is a 9.65 km (6 mi) tide.

There is a number of rare plant species and a surprisingly diverse ecology for its northern latitude. It is also part of North America’s largest expanse of peat bog. 

In this subarctic forest stunted trees can live for hundreds of years but rarely grow over 1.8 m (6 ft). These spars forests provide little shelter from the wind so branches generally only grow on the south side of the tree. 


Ideal Time To Visit

Late February and early March is an magical time to visit if you want to see the wildlife prepare for spring. While space is limited, at this time of year a lucky few dozen visitors can experience polar bear mothers and newborn cubs as they leave their dens and explore the snow for the first time.


Wapusk in the Winter

While most polar bears spent the winter doing the majority of their hunting for the year on the frozen platform of Hudson Bay, pregnant polar bears arrive on the shorelines looking for deep snowdrifts and snowy mounds on the small hillsides where they can build maternity dens.

While polar bears do not hibernate, these pregnant polar bears look for a place that they can dig a den big enough to give birth to their tiny cub(s). 

A polar bear cub needs a sheltered den because they are born blind and have thin hair would hardly protect them from the cold. A newborn cub is about 30 cm (11.8 in) and weigh less than 0.9 kg (2.0 lb).

The cub is highly reliant on their mother to keep them warm and provide their milk, which is extreme high in fat so the cub can grow quickly. 

The winter is a quiet time for most of the wildlife in the park but especially for the new polar bear families as they stay hidden from the wind and cold until spring begins to appear. 


Wapusk In The Spring

Spring is an incredibly active time in the park. Herds of caribou are starting to see green under all the snow. Wolves, foxes, and other predators can roam the land more easily and are looking for food for their new litters of cubs. 

Polar bears that have spent the winter hunting on top of Hudson Bay’s frozen waters are starting to notice the ice retreating, so they begin heading towards solid land like the coast or islands. Most of them will spend the summer resting and rarely hunting as they conserve energy and their fat levels. 

Since winter is such a competitive time for polar bears to hunt, they rarely are seen in groups and prefer to be alone in their designated territory. But in the spring time, when they are not interested in hunting, they are known to gather in small groups and play or socialize as they wait for the water to freeze again. 

The most exciting part of the spring for wildlife enthusiasts is the emerging of the polar bear cubs! The limited visitors can watch and photograph these intimate and remarkably rare moments when the cubs first get to explore this big snowy wonderland. 

Capturing these heart-warming moments as cubs play with their siblings or cuddle with their mother will leave you with incredible memories and fantastic photographs.
