OTTAWA  During the Winter Olympics last year, the main attractions in Whistler, British Columbia, were the skiing and sliding events. But tourists looking for something different could also book dog sled rides pulled by teams of “energetic and lovable Alaskan racing huskies.”

The rides were suspended this week after the Royal Canadian Mounted Police and animal welfare authorities in British Columbia said they were investigating what they described as an “execution style” shooting of as many as 100 dogs that took place after a business slump in the weeks after the Olympics ended.

Gruesome details of the killings surfaced Monday when a Vancouver radio station, CKNW, obtained a copy of a confidential decision by a workplace compensation board granting compensation for post-traumatic stress disorder to an employee who killed the dogs.

Both the killings and the compensation have outraged many Canadians and, according to the police, prompted serious threats against the company that operated the tours, Outdoor Adventures at Whistler.
