Seal hunters are thought to have already clubbed 70,000 harp seal pups, and thousands more will be killed this year for their fur and meat.

The hunters say they are just trying to make a living, and at the moment the numbers of seals in the area are so high they are threatening fish stocks.

But animal welfare groups say sealers are breaking the rules by slaughtering the animals in a cruel way.

Seal pups aren't allowed to be killed before they are 12-days-old, but as their skins are whitest and softest when they're young, hunters mainly target pups who are under a month old.

Both America and Europe banned bringing seal products into their countries, and the trade in Canada dropped off.

But now demand for fur - including seal skins - is back, with countries like Russia and Poland wanting them to make hats and clothes.

The International Fund for Animal Welfare (Ifaw) wants Canada to put an end to the killing.

"The Canadian Government has given the go ahead for up to one million seals to be killed over the next three years.
