An annual remembrance ceremony took place today to remember fallen police officers from across Ontario.

This morning, 257 names were read on the lawn of Queens Park during the 16th annual ceremony as officers from across the province came to pay their tributes.

The names of three officers were added to the wall of honour this year.

Constable Joseph Prevett, 50, suffered a massive heart attack while participating in a joint training exercise in Gravenhurst.

Corporal Matthew David James Dinning was deployed to Afghanistan and was killed when his crew struck an IED on the roadway.

Constable John Acton was killed in 1907 when he was badly beaten making an arrest in a laneway in Toronto.

The Lieutenant Govenor of Ontario, Elizabeth Dowdeswell, and Premier Kathleen Wynne were both in attendance today.

The CN Tower will be lit in blue on Sunday night to honour the fallen officers.
