The short answer
A licence is required for every London dog over six months. Register between January and July and it costs $33 if the dog is fixed and microchipped, $39 if fixed only, $63 if not fixed. After July 1 those drop to $23, $26, and $37. Buy it at the London Animal Care Centre, 121 Pine Valley Boulevard. Every licence expires December 31. Your leash cannot exceed 1.8 metres, and the household limit is three dogs.
Dog licensing is the piece of London pet ownership that adopters most often skip, usually because they assume it is optional or that a microchip covers it. Neither is true here. The City states plainly that dogs and cats within London are required to be licensed each year.
The Dog Licensing and Control By-law PH-4 is unambiguous. Section 3.5 states that no person who is an owner of a dog shall, within the City of London, fail to have a current valid licence for that dog. It applies to dogs over six months of age.
The good news is that the process is simple and the fee is modest, especially if your dog came from a rescue already spayed or neutered and microchipped, which nearly all London rescue dogs do.

Where and How to Buy One
London Animal Care Centre, 121 Pine Valley Boulevard, 519-685-1330. Handles both new applications and renewals. Three ways in: book an appointment by phone, walk in and register at the shelter, or register online. The online route takes roughly one to two weeks to process, so choose in-person if you want the tag in hand today.
City Clerk's Office, 300 Dufferin Avenue, 519-661-4530. Renewals only. If this is a brand new dog, the Clerk's Office cannot help you, and a wasted trip downtown is a genuinely annoying way to learn that.
Bring proof of your rabies vaccination, proof of spay or neuter, and your microchip number. Those three documents are what move you from the $63 tier to the $33 tier, so they are worth digging out of the adoption folder before you go. A rescue dog's adoption paperwork normally has all three on one page.
The December 31 Trap
London licences expire on December 31 of the year they were issued. That is a fixed calendar expiry, not a rolling twelve months from purchase. Buy a licence in early November and it lapses about seven weeks later.
The City clearly knows this, which is why registering after July 1 costs less: $23 to $37 instead of $33 to $63. It is a prorated second half of the year rather than a discount.
What this means practically: if you adopt in autumn, buy the licence anyway. It is cheap at that point, and it keeps you compliant during exactly the period when a newly adopted dog is most likely to bolt out an unfamiliar door. Then set a January reminder and renew at the standard rate.
Leash Rules and the Three-Dog Limit
The leash cannot exceed 1.8 metres. Section 4.10 of PH-4 deems a dog to be running at large if it is not under the physical control of a person by means of a leash no greater than 1.8 metres. That is roughly six feet. Most retractable leashes extend well past that limit, which makes them non-compliant when extended and, separately, a poor tool for control on a busy path.
Three dogs per dwelling unit. Section 4.1 caps the number of dogs kept in or about any dwelling unit at three, with exceptions for registered kennels, fostering organizations, and certain grandfathered situations. If you want to foster for a London rescue and already have dogs, ask the rescue how the fostering exception applies to you before you commit.
Off leash only where designated. The by-law contemplates areas the City may designate as off-leash parks where dogs may run at large. Those designated spaces are the only legal off-leash option. Everywhere else, including the Thames Valley Parkway, Springbank Park, Gibbons Park, and any unfenced green space, the leash rule applies. Designations change, so check the current list with the City or the LACC rather than trusting a park you remember.
Skipping the licence costs more than buying it
The London Animal Care Centre warns that failing to purchase a dog licence or cat identification can result in penalties, including an increased licence fee, an administrative monetary penalty, or court action. Set the money aside and the real point is this: the licence and the microchip are the two systems that get a lost dog home. A dog that slips a collar in a January snowstorm near Old East Village has a far better night ahead of it if both are current. That is worth $33.
