Ottawa police say they've identified all three young men who urinated on the National War Memorial during Canada Day celebrations, after photographs of the incident sparked outrage across the country.

Two of the young men are from Ottawa.

"Both are juveniles so they're not releasing their names, and no word yet on whether there will be charges," CTV's Rosemary Thompson told Newsnet Wednesday.

The third man, 23, contacted police but officials have not yet released his name.

Thompson said the suspects could face a mischief charge, and that "a lot of people are talking about what kind of community service these young men might have to do."

Sun Youth, a Montreal youth organization, had offered a $1,000 reward for information leading to suspects' arrest.

Thompson said heavy fighting in Afghanistan, where Captain Nichola Goddard became Canada's first female combat soldier to be killed in action last May, has made the memorial even more significant.

"I think people in Ottawa ... want to protect that monument because it means so much," said Thompson.

Dr. Michael Pilon, a retired major with the Royal Canadian Dental Corps, took the photographs.

He snapped images of the men defacing the Ottawa monument after the holiday fireworks on Saturday night.

The Tomb of the Unknown Soldier, built in front of the National War Memorial, holds the remains of an unidentified Canadian soldier who died in the First World War and represents the more than 116,000 Canadians who died in past conflicts.

Pilon, who served with the Royal Canadian Dental Corps, said most of the crowd reacted with cheers and laughter.

He sent emails to the offices of Premier Dalton McGuinty, Mayor Bob Chiarelli, the National Capital Commission and others, asking for someone to guard the memorial this year.

But he received no initial response to his request, he said.

The National War Memorial, unveiled in 1939, initially symbolized the response of Canadians in the First World War but has since come to commemorate the sacrifice of all Canadians who have served in times of war.

The Royal Canadian Legion plans to use the photos to pressure the government for increased security at the monument.

H. Clifford Chadderton, chairman of the National Council of Veteran Associations in Canada (NCVA), told CTV.ca that veterans' groups have been asking for more security since 1995 but especially since the creation of the Tomb of the Unknown Soldier in May 2000.
