It's the best quality you will get for swim classes in GTA!…read more I had lots of parents highly refer me to try this place, some even suck up the cost of hwy 407 to bring their kids here, which to me says a lot!! This company started in their parents backyard pool, upgraded to a shared motel pool and now finally has opened up a beautiful space of heir own in Box Groove plaza. I love how genuine everyone that works here is, they all truly care about your kid and they are not a number. My kid is fearful and they really give him such patience. Basic level starts with ratio of 1:3 but he's the only kid and they still run the class! Instructors are in blue rash guards and there's 2 pool supervisors that float between groups in Orange, so sometimes like twice throughout each class my kid has two instructors all to himself. Clean viewing area for parents to watch their kids, small children's play area for the kids waiting. Two tv's playing sports or cp24, lots of plaza parking. Only bad part is- Showers sometimes get "reserved" by parents leaving their bags there which they shouldn't be or people wearing dirty/wet boots into viewing area despite signage.

Update to my previous review. This place is nothing less than a 5 . The staff here have been…read moreextremely helpful and truly care about the progress of your children. First time with Russell Aquatics and we are off to a good start. My child has swam before through the Markham Community Center programs but he requires a program with a ratio that provides more one on one training. At Russell Aquatics, students in the Pre School 1-2 program have a 3:1 ratio. This is extremely beneficial when your child needs more attention which mine does. Even before we entered the facility the staff were already helping us with our first obstacle, a crying four year old. They came out to comfort him which in turn provided me with comfort. I will continue to update this post as my family continues to visit Russell Aquatics!

I had to escalate this to the Ontario Ministry of Public and Business Service Delivery and Procurement (File No. CAS-118402-S3D3H). Only after government intervention did the owner, Chris Mulchinock, agree in writing to send a refund -- but as of 01-21-2026, I still have not received it. See attached screenshots for documentation, including the government case confirmation, and the owner's written commitment to refund. This has been ongoing for months. If you're considering this gym, be aware that getting your money back may be extremely difficult. I will continue the path for the refund, and I will update this review if and when the refund is actually received.
