Cory Martin


When you meet someone who truly excels in a profession such as real estate, it can be easy to assume there was an element of luck involved. In Cory's case, everything in his life transpired to form his character and business ethics into a Broker that clients consistently trust and rely on to help them through one of the most important decisions in their life.

The majority of Cory's business consists of past clients and the referral of their friends and family. Cory's clients go out of their way to ensure their closest friends and family benefit from Cory's vast experience, dedication, and philosophy that puts the client's interest above all else. Once you have met Cory, you can't help but consider that many of these referrals are likely the best way his clients could truly say thank you for an outcome and a level of service that surpassed their expectations.

When looking back, for most 19-year-olds, a summer job meant cutting grass or scrubbing dishes. Cory Martin, already a licensed Real Estate Salesperson, was helping clients often three times his age to make great decisions in buying and selling their homes. A second-generation REALTORĀ®, Cory started his career with a work ethic that places great importance on hard work, honesty, and putting the needs of his clients before anything else. In his earlier years, Cory handled every aspect of the business himself. Photos, tailored marketing campaigns, market analysis, pricing strategies, negotiating, and coordinated transactions helped develop an intimate understanding of every aspect of the real estate industry from the ground up.

A lifelong Oakville resident, Cory's years playing AAA hockey instilled a strong sense of teamwork. Understanding that anything of importance needs a dedicated and talented team, Cory drew to himself the best in people in Staging, Photography, Marketing, Legal, and a host of other services vital to the success of his clients.

After graduating from the University of Western Ontario with his Bachelor of Management and Organizational Studies and an Honors Specialization in Global Commerce, Cory took a hard look at the industry and could not see a future in the national chain brokerage format that rewarded the success of the agent over the success of the client. Cory knew that any lasting success depended on a laser focus on the client's success. Teaming up with Glenn, he established Martin Group in 2009. The rest is history.

Today, Cory is the Broker and Co-Owner of Martin Group, where he assists clients throughout Oakville, Burlington, and the Greater Toronto Area. Having established a network of satisfied clients that spans the Golden Horseshoe, he has cultivated systems, analytical tools, and a workflow to meet the needs of virtually any transaction.

When listing a property, Cory's clients find great success in his statistical analysis and numbers-based approach. Creating statistical models and in-depth spreadsheets with detailed sales data removes the standard bias and personal preferences to arrive at an accurate and professional valuation that clients trust. As an added value, the data is often shared with cooperating realtors to help their clients appreciate the home's value and expedite negotiations. In Cory's own words, "Regardless of the market, finding the optimal price for a home is the best way to get my clients the most money, faster."

Elsewhere, Cory is just as attentive when assisting his buyers, drawing from his extensive knowledge of the GTA to uncover suitable homes and investments for clients. "Owning a home is not only a significant investment but also a lifestyle choice and an opportunity for our clients to create a prosperous life for their families," he says. "At the end of the day, we get so much enjoyment from helping them make such a huge life decision." Cory's approach is anything but passive: "We don't just sit around waiting for homes to come to market." Leaving no stone unturned, Cory reaches out into the community to pursue the dream home his client desires. Modestly going about his work, what often looks like a lucky break was hours of searching and a strategy that creates more buying options for his clients.

In the evolving world of instant information, Cory and Martin Group know it's their responsibility to provide clients with continuous market updates, statistical analysis, and, most importantly, the insight to help them make the best decisions regarding buying and selling. To quote one recent client, "I am so thankful to have had a team such as Cory and Glenn guide me down the road of home buying. It just makes it that much easier when you're working with people who care."

As a prominent and respected Broker, Cory has earned a strong reputation throughout the GTA for his professionalism and winning mindset. With the majority of sales coming from repeat clients and referrals and his team now crossing over $500 million in sales, he remains committed to the proven standards that have set Martin Group apart. "Since 2009, our team has been able to adapt to industry changes nimbly. Because we own the brokerage, we can pivot quickly with fluctuations in the market and offer key services that clients may not find elsewhere."

Along with spending quality time with his wife and their three daughters, Cory is dedicated to his community, with his team contributing to various events and charities throughout the year. Looking ahead, Cory is excited about his part in influencing the future of real estate. "We don't see real estate as a sales-driven industry," he says. "Rather, we see ourselves as trusted advisors for all our clients, providing the knowledge and experience to help them make great real estate decisions for them and their families."

When it comes to new subdivisions, we give up the mature neighbourhood feel we get in places where trees stretch out and form a green canopy over the street. We exchange this for the convenience of a newly built home in the suburbs with our choice of lot and floor plan, no repairs, and the thrill of being part of a growing community.

However, we frequently overlook the fact that even the most established neighbourhoods today were once brand new. Therefore, we must start like all the older generations and plant trees for our new homes!

So, What Can We Do?

The first step in creating or rebuilding a green canopy is to plant trees where possible on individual lots. It does take time, but not nearly as much time as you might think.

Aside from planting trees, landscaping your yard will help it look more established and comfortable. This will give your garden form and structure, as well as frame the front of your house, and they'll add beauty now and, in the years, to follow. There is an old saying, “the person who plants a tree knowing they will not see its maturity, understands the meaning of life."

Important Tip:

Plant in the fall. Most garden centres cut prices in the fall. You can either save money or get a much more mature tree for the same money. Really a win/win/win. For you, your neighbours, and the planet.

So, let's start planting trees in our newer neighbourhoods! This will not only help the environment, but it will also reward you when it is time to sell!

Contact The Martin Group today for more information, or to find you the right home with beautiful and plentiful trees.


The third-best sales record in TRREB's history was recorded in August 2021. Though the market has seen its normal summer lull, the need for owning homes is evident. Simultaneously, the availability of housing is on the decline. Competition among home buyers has been increasing in this tight market, resulting in double-digit yearly price hikes.






Stats retrieved from TRREB



As shown in the graph above, according to TRREB's MLS System, Toronto real estate agents in the Greater Toronto Area saw a 19.9% drop in home sales in August 2021 compared to the previous year's record of 10,738, and new listings filed in the system were down 43 percent compared to the previous year's record of 18,599. Despite the decline, the average selling price continues to rise with a 12.6% increase.


This year's low number of new postings is really troubling. It implies that there is an undersupply of housing, and this will worsen when immigration to Canada increases. With the approaching federal election in mind, the federal parties have all put a focus on housing availability and affordability. 


If we take a further look into The Halton Region, more specifically Burlington and Oakville, you will see that there has also been a tremendous decrease in the number of sales and new listings.








Stats retrieved from TRREB



On average, a property in Halton Region costs $1,070,911, up by 3.8 percent according to the most recent MLS data. While the number of sales dropped by 27.5 percent, there was also a 41.7 percent reduction in new listings.


In all three locations, it's clear that now is a great time to sell your home. As a buyer, however, it appears to be considerably more difficult due to a slowdown in new listings and an increase in home values.



Let's take a closer look at how particular property types compare in Burlington and Oakville.







Stats retrieved from TRREB


The average price for all property types in Burlington and Oakville has risen. Prices increased by 3.8 percent in the Halton Region alone for all property types. The average price for detached homes in all of the Halton Region increased by 20.8 percent as a result of their popularity. The increasing popularity of detached and semi-detached homes in Oakville and Burlington was reflected in their 21.5% and 19% growth, respectively.


Although the number of sales and listings have declined in Oakville and Burlington, these cities remain popular in the GTA, where home demand continues to rise.

It’s that time of year again, schools in session! The kids are all getting pumped up in hopes of a better school year than the previous year. As we all know, the pandemic wreaked havoc on children's ability to obtain a proper education, resulting in school closures that forced them to study everything online rather than in person. So what is the 2021/2022 school year going to look like in Oakville and Burlington?


The Reopening Plan for the Halton School Board

The Halton District School Board states that students and staff will be back in secure and productive learning environments by September 2021. They pledge to maintain an inclusive, safe, and discrimination-free environment.


The Reopening School Guide for September 2021 covers five areas: health and family, operations, instruction, wellness and technology. It is essential to understand that things may change. 


Health and family

  • Student Self-Assessment and Screening
  • Personal Hygiene
  • Physical Distance
  • Masks, including cloth masks and face coverings
  • Enhanced Care Cleaning Procedures
  • Environment and Air Flow Fountains for Drinking
  • Student Learning Communities
  • Potential student with COVID-19 prior to entering school
  • Potential student with COVID-19 at School
  • Personal protective equipment used by staff members



They've put out a daily operational plan for a school's involvement in ensuring the safe reopening.


  • Family responsibilities
  • Student belongings
  • The school’s outdoor play structures facilitate entrance and exit points
  • School hours and student access
  • Lunch and food items
  • Academic Calendar
  • Before and after-school programs, early childhood educational programs
  • On-the-spot crisis resolution



The School Board will implement the Ministry of Education's new approach by creating a few days dedicated to face-to-face education in methods that are both engaging and student-centered.



Staff members will need to focus on helping kids become reacquainted with one another and rebuild a solid pattern of support as they return to school after being away for some time. Guidance counsellors, social workers, and other school-based support staff will provide all the assistance that students need.



We will provide students' support through a program geared for those studying through Distance Learning.


The details mentioned are the Halton District School Board's intention to reopen. Their website provides access to further data, and you can also contact your children's schools for more information. 


We've all been swept into a new educational and cultural reality with the recent COVID-19 pandemic. Working together, we can minimize the problems faced by our kids as school begins again.
