The worst service ever. Soldered a gasket kit for a power tim unit. 4 weeks and nothing done. Went in to inquire about the parts ordered. Was told then they don't do parts. Wow!!!! Thus place is a joke AVOID IS ALL I HAVE TO SAY! If this is how they treat a new customer I wonder how their service is.

Unfortunately, I did not have a great experience with this marina.
I called to touch base regarding my boat as I had dropped it off for it to be worked on.
The young lady I spoke with was extremely rude to me and lacked any customer service skills.
After the phone call ended, she called me back a few times and hung up on me intentionally every time.
I tried to contact the owner of the marina and he never called me back.
This was the worst experience I’ve had with a marina in my 20 years.
Sadly, I won’t go back after this.

Staff is very rude. They obviously have too much business. Very overpriced and make prices up as they go. Not the same place it used to be that's for sure. Dishonest. Don't recommend.

Great place to keep your boat or for repairs. Excellent mechanics. Prices are reasonable when compared to other marinas also considering it's very close and convenient to lake and amenities.

In 2020, I purchased my boat and used the boat launch at Keswick Marina. I always thought that the marina was situated in a great place on Cook's Bay in Lake Simcoe, and that they offered tremendous value. I had Keswick Marina winterize and store my boat for the winter.
In May 2021, I requested that the marina "summerize" my boat and get it ready for the water. Shortly thereafter, I received a call from the marina and received some bad news that the mechanic had found an issue with the water pump and some other stuff. The total estimate to fix everything was over a $1,000, as parts were difficult

It’s been a while since I’ve been there but it was my favourite place to launch my boat. The owner Harry was a real gem and always helped me launch my boat ! Honestly it’s the marina has given me the best customer service on Simcoe !

Terrible service - took my boat in to have it winterized and a small repair to a tear in the vinyl seat and they broke the seat in 2 pieces - did nothing on it from Oct 2017 until I picked up in May. I called in in Nov and was told the seat was repaired - was not and are now saying the seat was broken when it went in. Would not suggest anyone use them - if you are not a regular with a boat in their marina they don't care - have no idea what they are doing. Poor service and rude - not our problem attitude.
