Greetings from a friendly neighbor from the north! I'm currently residing in Brampton, Ontario- in Canada. I did some research on local laws in the three cities. Since I have family in Mississauga- had to research there, Brampton for my own purpose, and Caledon- where I will be moving too shortly. I hope this can help someone out there. I spoke to by-law officers directly as well as city hall. For Mississauga: - City does not permit any fowl of any type Bylaw officers advise: - Don't keep roosters - They don't come looking for backyard coops unless a neighbor complaints For Brampton: - City allows 2 hens to be kept - No roosters For Caledon: - If your zoned residential, no backyard fowl of any type This sort of got me puzzled because the lot sizes in this city are in the acres. So I did approach a by-law officer about this. Bylaw officers advise: - We won't come looking for backyard coops unless a neighbor complaints - Keep your neighbors happy by giving them a basket of eggs every so often - Use pine chips to keep the odor down I hope this helps anyone from any of these cities.
