Meet Monica Simpson
Since 2006, I’ve transformed over 3,000 dogs and families across Toronto. As a Grand Master Trainer and Behaviour Therapist, I bring a unique perspective shaped by my professional background in psychiatry and my Master of Health Science in Health Care Administration and Management. While human behaviour is incredibly interesting, I recognized early that dog behaviour holds equally fascinating complexities. My expertise in understanding behaviour patterns and systemic change translates perfectly into helping families transform their relationships with their dogs.
After adopting a rescue German Shepherd named May with serious behavioural issues, I discovered that my own training methods, which had worked with my other dogs, simply weren’t enough. Skeptical but desperate, I turned to Bark Busters and experienced an immediate shift in hope and understanding. That pivotal moment, when my trainer suggested I might have a gift for this work, became the catalyst for an 20-year career dedicated to helping families. As a certified Behaviour Therapist and Trainer, I specialize in changing the relationships between people and their dogs, understanding that proper communication can literally save a dog’s life.
My mission is simple: help dog owners understand their canine companions so they can enjoy relaxed, happy dogs.
It is so rewarding to have the opportunity to change the relationships between people and their dogs. Life is a lot more fulfilling when you understand each other, and in the most serious situations, it can help save a dog’s life.
Did you know that each Bark Busters trainer & certified behaviour therapist is required to pass an aggressive dog safety program that keeps hundreds of trainers safe worldwide. All trainers are required to understand different types of dog aggression, fear and trauma, and know how to approach each situation calmly and safely. You are always in good hands with Bark Busters!

We Understand How Scary
Dog Aggression Can Be
You love your dog, but their aggression is affecting your entire family:
- You’re afraid your dog might bite a visitor, a child, or another dog
- Walks have become impossible – your dog lunges, barks, and pulls toward every dog or person
- You can’t have guests over because your dog growls, snaps, or shows teeth
- Mealtimes are tense because your dog guards food bowls, toys, or sleeping spots
- You’ve been told your dog is “too aggressive” for group classes or daycare
You’re not alone. Aggression is treatable – and we can help.
Why Our Approach Works Where Others Fail:
- In-home training addresses aggression where it actually happens
- No punishment, no physical force – this makes aggression worse
- Communication-based techniques that create lasting change
- You learn to read and redirect your dog’s triggers
- Visible improvement often in the first 2-2.5 hour session
- Lifetime Support Guarantee – you always have the help you need from Bark Busters.

Dog Aggression Training FAQs
How much does training cost?
We offer a one-time fee that includes your initial assessment, dog training sessions, and lifetime support. Pricing depends on your specific needs. Contact us on the form above for an accurate quote.
How quickly will I see results?
Most clients see noticeable improvement during the first session. As Mabel shared, “I’ve never seen Comet so calm and well behaved” after just one session. Long term habits take consistency, don’t forget! We schedule follow up appointments to suit your dog’s needs, and help you! Your lifetime guarantee means you always have the support you need.
Do you train all breeds and ages?
What if my dog is aggressive? Is training safe?
Aggression is one of our specialties. Each Bark Busters trainer is trained on our unique “Stand Rite No Bite” system, and must pass a test to make sure they know how to safely approach aggressive situations. We use safe, effective communication techniques, and coach the humans on how to address the root cause of aggression to create lasting change.
Why in-home training instead of group classes?
What does "lifetime support" really mean?
Do I need special equipment like bark collars?
We do not use any form of shock collar during aggressive dog training. The Bark Busters East Toronto dog trainer will assess and advise you on what your specific dog will need. You do not need to go buy anything ahead of time.
How long are training sessions?
The initial session is typically 2-2.5 hours. This gives us time to assess your dog, teach you effective techniques, and start seeing results immediately. Follow-up sessions are typically an hour.
What areas do you serve?
We serve East Toronto, Surrey, Delta, New Westminster, Langley, East East Toronto, Kitsilano, Shaughnessy, Ladner, Tsawwassen, White Rock, Abbotsford, and surrounding Lower Mainland areas.
