It's another four years of tax increases capped at two per cent.

That's Jim Watson's latest promise if he's re-elected as mayor at the Ottawa Municipal election on October 27.

"We've brought taxes down each and every year I've been in office and my commitment on a go forward basis is to bring it down even further," says Watson.

Watson made a similar promise when seeking office four years ago. He capped taxes then at 2.5 per cent.

Still, there were some Ottawa services who had difficulty coping with the cap. The Ottawa Police Service stating the effects on its budget could mean less officers on the ground.

Watson says his priority is to keep a balance of what the city needs and what it can afford.

Mayoral candidate Mike Maguire says he wants to know what Watson plans to do about other fees residents must pay.

"They haven't addressed the user fees...They also haven't addressed the enormous profit Hydro Ottawa makes and will continue to make," says Maguire.

According to the Real Property Association of Canada, Ottawa had the highest property taxes in Ontario. The capital also beat out major cities across the country including Vancouver, Calgary and Toronto.

"We have some unique challenges when it comes to running our city. We are the largest big city in the country," says Watson.
