The Labrador Sea is between Greenland, Labrador, and Qikiqtaaluk:
A Greenlandic source on polar bears states:
In Greenland the polar bear lives and breeds in the northernmost parts of West Greenland and in Northeast Greenland, but is also occasionally seen elsewhere in Greenland, as it moves with the drifting ice.
However, it is extremely rare for either local inhabitants or tourists to see a living polar bear. The chances of seeing a polar bear are greatest when sailing by ship along the coast.
On the other hand, Parks Canada for Torngat Mountains National Park (northern Labrador) states:
Polar bears are true carnivores and can be a significant risk to human beings. Visitors travelling and camping in the park are in polar bear country and are at high risk of encounters. Polar bears are almost always present along the north Labrador coast.
The observation that polar bears are more common in Labrador than in southern Greenland is supported by Derocher (2010), Nature:

Polar bears like the sea ice edge, but this is very far from either Labrador or Greenland when at its fall minimum. When sea ice is at its spring maximum, both Labrador and almost all of Greenland are packed deeply in ice (see maps below).
Then why are polar bears so much more common in Labrador than they are in southern Greenland? Arey they really? And how do they survive all summer long, when the sea ice is very, very far away? The occasional tourist might not be enough, I guess.
