The administrator of the Facebook page, Jackie Galland, posted a message today saying the police wanted to shut it down and asked for support; that attracted 200 'likes'.
However, Mr Canning said he met Ms Galland yesterday and had asked for it to be toned down, not closed down.
"We had an in-depth discussion and I'm disappointed with the outcome," he said.
"We have no problems with the page stating where checkpoints are and asking people to slow down - that's what we want - but when it's used as a personal hate page against police and to air what has been heard on the police scanner, it becomes an issue for us.
"Some things could be posted on the page, perhaps, before all of the facts are known, and this is where the problems begin.
"If the page was just being used to advise people of where police have set up speed cameras there would not be a problem," Mr Canning said.
