Police officers gathered at Queen's Park on Sunday to honour the scores of men and women who have died on duty across the province over the decades.

This year, the names of two young Ontario officers, who died nearly a century apart, were added to a memorial wall. Const. Jennifer Kovach, a 26-year-old Guelph officer, died in a collision earlier this year.

"The loss of Jennifer is a terrible tragedy but this ceremony will ensure that her service is never forgotten," Mike Abbott, president of the Ontario Police Memorial Foundation, told the solemn crowd at Sunday’s ceremony.

"Her name is now forever engraved in these granite walls alongside 252 other heroes. Jennifer truly was a hero in life," he said.

The other name added to the wall was Const. William Rourke, an Irish-born officer who died on duty in 1915.

Premier Kathleen Wynne said that many years may have passed since Rourke’s death, but his sacrifice should not be forgotten.

"His service should never be dimmed by the passage of time and we will not forget everything he did to make our province a safer place," she said.

The name of each of Ontario's fallen officers was read aloud on Sunday, right before pipe bands lead an honour procession around Queen’s Park toward the monument.

The remembrance ceremony takes place each year on the first weekend in May.
