The suspects are in Washington, Alaska and one is believed to be in Illinois. A Canada-wide warrant for participation in a riot and other charges has been issued for their arrests, said Vancouver Police Constable Brian Montague.
"All three are aware that there is warrant out for them right now," said Montague, who added the suspects were told of the warrant by their local police and know they will be arrested if they try to enter Canada.
Two of the suspects are Americans, but one is a Canadian citizen from Vancouver believed to be studying in the U.S.
An application to U.S. authorities for extradition is being considered, but has not officially been filed, said Montague.
"That's something that crown counsel has to make the decision on, they have certain criteria regarding extradition," he said.
A handful of people have been sentenced for their role in the riot that erupted after the Vancouver Canucks lost game seven of the Stanley Cup final to the Boston Bruins on June 15, 2011.
The Crown has laid more than 300 charges against 100 people since the riot.
But, authorities predict they will have laid more than 700 charges against upwards of 225 people by the time they are finished with the case.
