Violence has also occurred in Canada, where at least three doctors have been attacked to date. The physicians were part of a pattern of attacks, which targeted providers in Canada and upstate New York (including the fatal shooting of Barnett Slepian of New York). All victims were shot, or shot at, in their homes with a rifle, at dusk or in the morning, in late October or early November over a multi-year period. There is speculation that the timing of the shootings is related to the Canadian observance of Remembrance Day.
