Durham Regional police said Friday they are looking for several suspects in connection with a mass shooting in Whitby, just east of Toronto.
Four males were shot inside an elevator in an apartment building at about 12:30 on Thursday afternoon.
One of the males is in critical condition. The others are expected to recover from their injuries.
A fifth person - a 17-year-old male- was hit by shrapnel.
Investigators say they are searching for three or four suspects, who they believe carried out the shooting.
Police have not released any names.
