After more than three decades with the Royal Newfoundland Constabulary, Chief Robert Johnston announced on Thursday that he will retire at the end of February.

Johnston was appointed chief in the spring of 2010.

At a news conference on Thursday afternoon, Johnston told reporters that some of his reasons are personal – his wife retired last year – and other reasons are professional, such as the completion of the RNC's new headquarters.

Johnston said it's also time for renewal, as the RNC sets out to develop a new strategic plan for the future.

"Early this year, in the next month or so, we need to buckle down and start working on our strategic plan for the next three years. So I believe whoever is going to lead that strategic planning process should stay around and execute that plan — and I think it would have been unfair for me to lead that process and then pass it to someone else," he said.  

Johnston said he's comfortable leaving at this time because he has confidence in the team he's leaving behind.
