A pack of wolves in Banff National Park has diminished significantly after just one year.

Police are asking witnesses to come forward in the "targeted" daytime shooting of an alleged Vancouver gangster in midtown Toronto, while releasing limited information on the suspects or the victim's criminal past and admitting their investigation is operating within a "vacuum."

A new wolf pack spotted in Pacific Rim National Park has prompted a warning from park officials to visitors as the wolves appear to have little fear of humans.
