Municipal By-Laws in Ontario: How They're Made and Challenged

Ontario's municipalities get their powers from provincial laws, mainly the Municipal Act, 2001 and, for Toronto, the City of Toronto Act, 2006. Councils use those powers to pass by-laws.

How a by-law is made

1. Staff prepare a report and a draft.
2. A committee and then council debate and vote.
3. Many by-laws, especially planning by-laws, require public notice and meetings.

Enforcement

• By-law officers investigate complaints and issue orders or tickets.
• Many municipalities use administrative penalties, with screening and hearing reviews, instead of court.

Having your say

• Contact your ward councillor.
• Speak at a committee meeting (deputations are often allowed).
• Comment during public consultations.

Challenging a by-law

• In court: the Superior Court of Justice can quash a by-law that is illegal, for example passed without the proper power.
• At the Ontario Land Tribunal: many planning decisions, such as zoning by-laws, can be appealed, subject to rules on who may appeal.

Deadlines for challenges can be short, so act quickly.
