While officials deliver Ottawa's new official plan, a group of residents will hold a demonstration outside city hall Tuesday to urge decision-makers to grow the capital in a responsible manner.

City staff have proposed adding 850 hectares to the city's urban boundary, but members of the Coalition for a Sustainable Ottawa are asking council to hold the line on the urban boundary, said rally organizer Will Murray.

"We're keeping it positive," said Murray of the rally, which begins at the Human Rights Monument at noon.


"We hope the city of Ottawa knows that the residents want the city grown in a responsible manner within the set urban boundary," said Murray.

The city subsidizes urban sprawl, said Murray. It's more expensive to provide services across a wider area because the city has to put in new sewage and infrastructure, he said.

In terms of transportation, building outside the urban boundary makes it harder to design transit services, Murray said.

"A transit system that has to cover a greater area is going be a less efficient service," he said. "It will encourage people to get back into their cars."

Building outside the urban boundary also makes it harder to deliver social services people require, Murray said.

So far, city councillors Alex Cullen, Peggy Feltmate, Diane Holmes and Clive Doucet have indicated their attendance. Speakers include representatives from the Sierra Club of Canada, the Glebe Community Association Ecology Ottawa and Services for New Canadians.
