There is no greater compliment than a satisfied client

Jack is the perfect realtor. We first viewed cottages 10 years ago with Jack and though we didn't find the cottage we wanted then, Jack kept in touch over the years. Unlike other realtors who just put you on an auto- maillist, the options he sent us over the years were highly tailored to our criteria. When the perfect place came up 4 years ago, Jack phoned us the day it went up to encourage us to have a look. He knew it was perfect for us. We went the next day to look and purchased it that night. It is our piece of heaven and we couldn't be happier on Whitefish Lake. Jack is completely honest, always pointing out the pros and cons of each place, and has huge expertise in the muskoka parry sound area. He is a rare and wonderful person.

We were referred to Jack by our close friends who had worked with him to buy their cottage on Lake Rosseau. Jack worked with us patiently for several years until we found our perfect island on Lake Rosseau this summer. He is honest, has a vast knowledge of Muskoka and is passionate about helping his clients find their perfect retreat. I have worked with many agents over the years, both personally and professionally, Jack is simply outstanding. Both he and Carrie were a pleasure to work with, we highly recommend Jack.

Jack was recommended by a friend of ours as he is an expert in the Muskoka area. Jack was efficient in getting back to us on any questions we had and was prepared to tour any property at any time when we wanted to see it.  When our dream property came on the market, Jack was there not only to show us the property, but also went above and beyond including contacting valuation experts, lawyers, and planners to better understand the property and ensure we put in an appropriate offer. As a result of Jack’s diligence and hard work, we were able to secure this property. Even after our closing, Jack is always willing to help us in any way including introducing us to local experts, providing his opinion on building design, etc. We are forever grateful to Jack, Carrie and their team.

Jack is one of the most experienced agents in Muskoka. His honesty and knowledge of the area will keep buyers from purchasing a property that he knows would be a mistake for them. He can pretty much provide a cottage inspection for you while walking a property and is able to point out issues that a purchaser may not have even thought about. He is realistic about market conditions and works hard to put together deals that both the purchaser and vendor can feel happy about. Highly recommended. Thanks Jack!

Bruce Macdonald l Muskoka Cottage Buyer 

Jack came highly recommended to us and we couldn’t be happier. We were excited to purchase a family cottage on either Lake Rosseau or Joseph. We found a property that we liked however the cottage wasn’t quite the perfect fit. Jack urged us to hold off purchasing as he knew we wouldn’t be 100% satisfied. He knew of a perfect cottage on a special piece of property that was going to be available, although it was not listed at the time. Through his connections in Muskoka real estate he was able to get us a viewing and he expertly negotiated the purchase and all the terms before it came to market. We highly recommend Jack Janssen!

P & A Brown l Lake Joseph 

We approached Jack Janssen on the recommendation by a close friend who purchased a cottage through Jack.  At the time we first called Jack we were renters, just peeking into the Muskoka Cottage Market.  Over a two year period Jack patiently took us to see properties and made suggestions.  During this process he learned what we really wanted in a cottage.  When he found a place that fit our expectations he insisted we have a look and voila, he was right. We loved it!  We closed in October and now look forward to many years at our place in Muskoka. Thanks Jack.

W & M Stewart l Lake Muskoka 

Jack was recommended to us through a friend who also was referred to him through a friend. I followed up with a call to Jack, and his upbeat and positive manner reaffirmed that we were in good hands. Jack, thank you!  We lost count of how many years it has been, but you stuck with us and found us a beautiful property. All the testimonials speak to your knowledge and expertise, your thorough approach, and your no pressure guidance. This was also our experience and we would like to add that we appreciated your honesty, and that you truly went above and beyond to make this property ours. It is very exciting to be making a home “up north”, and you contributed to making it a wonderful experience.

J. Robins & J.Wortzman l Clear Lake, Muskoka

I sincerely want to thank you for your patience and guidance during the purchase of our property. We had been searching for almost five years and had worked with three different agents prior to working with you. At a time when road access to the property we ultimately purchased was not even close to being complete you took the time to hike the 40+ acres multiple times so that my entire extended family could be included. The purchase involved severances, road agreements, easements, etc. and because it was ‘land only’ the transaction was complex to say the least. I am certain that this purchase would not have finalized without the knowledge and professionalism you displayed throughout the entire process. You are a true statesman. Mayor of Muskoka is a befitting title. We look forward to building our family compound, raising our children and ultimately retiring there. It’s the perfect property for us now and for future generations to enjoy. We are genuinely grateful for everything you have done. Thank you, Jack.

Just Okay



I am a site development specialist and building contractor who first met Jack many years ago when he contacted me on behalf of one of his clients regarding structural elements on a Lake Rosseau boathouse. The next time I met Jack he was on a cell phone with one of his clients while walking around in knee-deep water checking out the lake bottom. At this point I thought ‘this person is thorough’ and if I was ever looking for property myself I knew I would contact him. Jack's knowledge of waterfront in Muskoka is exceptional. A few years later I was looking to buy waterfront in Muskoka so I contacted Jack and he successfully negotiated the deal. Since then I have worked with Jack both reviewing properties for his clients and for my own numerous purchases of property throughout Muskoka. Some of these transactions were for large, complex frontages which are not straightforward transactions.  Jack's expertise and guidance was one of the main reasons I ended up with my absolute dream piece of Muskoka waterfront. Thanks Jack.

Peter Groza of Evergreen Homes l Bruce Lake, Muskoka

We met Jack 5 years before purchasing our cottage and told him we were interested in Muskoka. Jack stayed in touch by sending periodic updates. It was an education of sorts, helping us focus our wants and needs. When the time came to look, he made sure we didn't waste our time looking at properties that weren't going to fulfill our wishes. His editing of listings was thorough, and his opinion was clear when I thought a property might be the right one to buy, or even one we should visit. Jack knows Muskoka so well you feel like you cannot go wrong because he will not let you make a mistake. He listens to your wishes and keeps you on track to fulfill the dream....even if it takes a little longer to get. When we finally did find the cottage of our dreams, Jack's skills in negotiating a deal that bridged the gap between us and the sellers was impressive, leaving everyone feeling good in the end. Cottage country is completely different from the city, you can make so many more mistakes in a purchase. That's why working with Jack was great, because he took the time to get to know us, our family, and helped us realize our dream of owning the perfect cottage.

Lyane & Dorian l Lake Joseph 

Jack I wanted to send you a brief email to thank you for your excellent service and salesmanship in selling our cottage.  It was a pleasure finally dealing with an agent that knows what they are doing and is extremely knowledgeable in the Muskoka region. Your ongoing commitment, perseverance and friendship was greatly appreciated and now someone else has a beautiful cottage to enjoy.  We hope to deal with you again soon.

Michael & Frances l Lake Rosseau

Jack is a very knowledgeable real estate agent in his field and has demonstrated his talents and skills time and time again with every experience I have had in dealing with Muskoka real estate. An agent that truly cares about your prospective purchase or sale like Jack does is a rare find.
I would highly recommend Jack if you have any real estate interests up in the Muskoka area and in need of a high quality dependable real estate agent.

Dr. Randy Rubenstein l Skeleton Lake Island 

We first met Jack during the showing of a property he had listed in Muskoka. As it turned out, that property was not for us but we started a dialogue with Jack about our situation and the nature of the property we were looking for. We had enjoyed many summers in a family compound on Lake Rosseau, so had the benefit of knowing the lakes fairly well and had a sense of property values in Muskoka - we knew it was going to take some time to find a place that we really liked and could afford to make our own. Jack was very patient with us – he kept us up to date and showed us numerous properties we might be interested in for over five years. Throughout that time Jack was thoughtful, informative and resourceful – even though we were slow to ‘pull the trigger’ on a purchase. Ultimately, Jack’s diligence resulted in an early ‘alert’ concerning a new listing on a Thursday afternoon, followed by a viewing the next day and a competitive offer from us which was accepted on the Saturday. Jack had found us a property that was exactly what we were looking for and he put us in a position to be able to get it in a competitive situation! Thanks Jack!

Linda & Edward Sellers l Morgan Bay, Lake Rosseau

Jack: What a wonderful first weekend at the cottage, what a wonderful property. Marilyn and I want to thank you for introducing the property to us, for your straightforward and honest representation. It was a pleasure to deal with you, and we will not hesitate to recommend your services to our friends and acquaintances who may be looking for a Muskoka property in the future. 

Tim & Marilyn Best l Lake Joseph

I have worked with Jack for over 8 years. We selected Jack to represent us for the sale of our old Cottage and a purchase of a replacement cottage. Jack was selected because of his extensive knowledge of Muskoka properties. We had a challenging sale and Jack worked hard for over three years to help us through the challenge. He never gave up and we are now the proud owners of an Olde Muskoka cottage on Lake Rosseau. We highly recommend Jack for any of your Real Estate needs. He knows the Muskoka market intimately and will always steer you in the right direction. 

John & Hilary Abell l Lake Rosseau

Jack is an expert at what he does! His knowledge and experience are incredibly valuable when it comes to real estate transactions in Muskoka! Jack helped us (very patiently) search for our property over a two year span. As someone who works in real estate every day, I can tell you that Jack is very good at being creative and providing valuable advice when trying to make what can be an emotional decision especially when it comes to cottage properties. I highly recommend him for your real estate needs.

Mike Leschuk l Lake Rosseau

As we near the completion of our cottage, I can’t begin to tell you how pleased we are with the entire process. Your patience (7 years) with us on educating ourselves to find the right property paid off! I must add that the full service that you provided from dealing with the municipality, septic and fishery approvals as well as helping us find the right builder was a huge bonus for me and something I quite frankly did not expect. Please feel free to have anyone contact me should they like to discuss your services and how you made the entire process easy and enjoyable. Thanks for making our entry into Muskoka such a pleasant experience.

Peter Menkes l Little Lake Joseph

Not only have we used Jack for our own RE transactions, we have recommended him to many friends. Not once have we been disappointed in any way. He is exceedingly knowledgeable and works hard both before and after the sale to ensure you are happy with all aspects of your purchase. He is very personable and warm, and has earned our trust on many occasions.

Theresa Mersky l Lake Rosseau Islands

Jack worked patiently with us for several years educating us on Muskoka and the market. We were very happy with the great service and with our purchase of our property on Lake Joseph. We used him again when selling our property and again enjoyed excellent results. I heartily recommend him. 

M & D Locke l Lake Joseph

Thank you for all your help in closing the sale of our cottage on Clear Lake. We have had several real estate dealings in Australia, England, the United States and Canada so we are familiar with the fact that problems often arise during sales. We have never received such willing, helpful service in closing purchases than we enjoyed from you. Your tireless efforts in overcoming obstacles showed a most intelligent approach in supplying answers to diverse questions posed by our lawyer.

Tom Davey l Clear Lake, Muskoka 

Just a quick note to say thank you for all of your efforts and help in selling our cottage. In the 14 odd years that we have known and dealt with you, we have always regarded you as being totally professional. We appreciate that you have always indicated that you are prepared to go above and beyond simply being a real estate agent interested in making a sale. We appreciate that over the years you have always been helpful in providing clear, unambiguous advice regarding any number of issues which, we as cottage owners, had to address, and in recommending trades people, legal advisors, etc. You have always been very diligent in keeping us up to date, both with respect to the progress of our initial purchase back in 1998, and with respect to our subsequent sale this year. We would not hesitate to recommend you to any of our friends and colleagues that might be looking to buy or sell property in Muskoka.

Orest Moysey and Kelly Patrick l Lake Joseph

We appreciate your (Jack and Carrie’s) persistence in locating a property suitable to two people that had very different ‘wish lists’ about what our ideal cottage should be. We valued very much your local market experience and the advice you provided about each property viewed, as well as what not to view. Thanks for assisting our entry into the Muskoka market. We look forward to our first summer at the new place. We will recommend you to any friends that might be looking to buy or sell property in Muskoka if the opportunity arises.

Lorne & Christina l Leonard Lake, Muskoka

My wife and I have bought a home and sold thru JACK. Professional and ethical would best describe Mr. Janssen. He looks out for his customers and nothing gets missed in his transactions. I highly recommend JACK and he is a TRUE MUSKOKA expert.

David Hind l Lake Joseph

I just wanted to thank you on your outstanding performance on my property. You are truly Muskoka Jack!!! We will definitely keep you in mind if we are looking for a property in Muskoka. Once again thank you. Btw my favourite champagne is Dom Perignon.

Philip and Shery Locilento l Clear Lake, Muskoka

We are still amazed that after such a brief trip to Muskoka you found us the perfect retirement package. And to think we live in Beijing China - you served us professionally and never pressured a sale but knew what we wanted. And we found it and did the transaction remotely with your help. As returning Canadians we are grateful and please drop by this summer for visits.

Nicola Cunningham l Lake Joseph

Excellent efforts and results in selling our Lake Joseph cottage. You did a great job researching and marketing the property, and then continued this professionalism by continually updating us with status reports and efficiently coordinating visits by prospective purchasers. Thanks again for a job well done. You really earned your commission on this sale.

Brian Smith l Lake Joseph

Sandra and I quite often think of the hard and successful work that you put in to help us realize our goal and we are truly thankful for your assistance. We particularly appreciate the fact that you did not get discouraged with the long and protracted negotiations over the purchase of the property and kept bringing new and creative ideas to assist in the realizing of our goal. 

J.F. Rose l Little Lake Joe

Love Muskoka Landscape? Feast Your Eyes on This Vacant Waterfront Property

We absolutely love the property and can't thank you enough for your help not only with the purchase but for your incredible service after the sale. We have bought and sold several properties and you were by far the most informed, helpful agent we have ever dealt with.


Your tireless efforts in overcoming various obstacles showed a most intelligent approach in supplying answers to diverse questions posed by our lawyer.


We would be pleased to recommend your services to anyone who is considering buying or selling a property. Having identified a suitable property we appreciate the professional and ethical manner in which you assisted us in negotiating a fair and reasonable price while suggesting creative ways in which the transaction could be structured to be cost effective for both the seller and the buyer.


What can we say - Second time around was even better than the first. You were great in getting us our starter cottage several years ago. Our family has wonderful memories. You always kept in touch, being more of a friend than a real estate agent. When we wanted to upgrade you were once again excellent to work with.
