More personal freedoms violated

With cities and provinces going smoke-free in public places it didn't take long for the do-gooders to try and expand the scope of the law. Now Ontario is talking of banning smoking in private vehicles when there are children in the vehicle. While subjecting children to second hand smoke is not good, it still should be a decision of the parent to not smoke. Will the law be extended to include private houses, apartments, etc. and then to anywhere on private property?
