The plan is included in the web-based "Ontario Plan: A Framework for the Future," which provides a 20-year outlook of the city.
Now, planning staffers are holding a series of open house meetings over the next four months to discuss how these updated land change uses may impact residential, industrial and commercial property owners, said Jerry Blum, director of the Planning Department.
Another meeting was held Tuesday night at City Hall.
The policy plan portion included updating land use, mobility, community design, economics, environmental impact, safety, social resources, housing as well as parks and recreation issues.
Known as the "General Plan-Zoning Consistency" program, the community meeting provided property owners with a chance to have one-on-one discussions with staffers about any of their concerns, he said.
Owners of the affected zone changes have been notified by mail about the meetings.
Blum said the city made a significant amount of zoning changes such as turning agricultural uses to residential and raising the density level.
Because of the updates to the General Plan, some properties are now zoned in areas not applicable anymore, he said.
"There's a lot of older agricultural animal uses, some are legal and some are not, but a lot of people feel that they feel the right to have horses and pigs.
But Blum said he doesn't believe there are too many illegal buildings in the city, adding the city has a thorough process with zoning code changes and the building department. He is confident that 90 percent of the changes will be in compliance.
"There's going to be 1 to 2 percent that we're going to have to sit down with owners of the property" to come to a resolution, Blum said.
