Take the change of name — out with O-M-B, in with L-PAT, Local Planning Appeal Tribunal. So imaginative. For more than a decade Ontario municipalities have had the ability to set up a “local appeal body”, instead of the OMB, for certain local land use planning matters, although no municipality has so far done this.  Well, let’s just make the OMB sound like it’s that kind of body — one concerned with your local issues. Of course, it will still be a provincially-appointed board that hears appeals mainly on municipal planning issues. So this is a symbolic gesture.
- is “inconsistent with” the Provincial Policy Statement, or
- “fails to conform with or conflicts with” a provincial plan, like the Niagara Escarpment Plan or the Plan for the Greater Golden Horseshoe, or
- “fails to conform” with an upper-tier plan where there is one. 
The introduction of a clear-cut threshold for appeals may seem like a big deal, but it is really just doubling down on existing requirements. Hello, do we not already have a policy-led planning system? Section 3 of the Planning Act already says that planning decisions have to be consistent with the PPS. Legislation establishing provincial plans already requires that municipal plans must conform to them.
Note 4: As mentioned in the December 4, 2016 post, the “have regard to” injunction seems superfluous if not disingenuous, since of course an appeal body would carefully consider any decision it was being asked to overrule.
