Tony Fleming presented on lessons learned from waterfront planning cases before the Ontario Municipal Board (OMB). Official plans that described water setbacks as protecting both the environment and aesthetic character were more likely to be upheld than those focusing solely on the environment. Cumulative impacts and precedent were also considered. Municipalities have authority to zone land covered by water and regulate legal non-complying structures, though uncertainty remains after a court decision. Options for municipalities include interpreting that decision narrowly or broadly.
