Built different.
By design.
In 2013, Mark walked away from an engineering career. Not because real estate called to him. Because it needed him. Million-dollar decisions were being made on gut feel and narrative. The numbers were there. Nobody was reading them. He saw that gap the way an engineer sees a design flaw: clearly, immediately, and with a very specific idea of how to fix it.

UNIVERSITY OF WATERLOO, B.ENG MECHATRONICS ENGINEERING
"Four years studying how complex systems fail and how to stop them from doing so. The same thinking applies to a real estate transaction."
2010 – 2013
MECHATRONICS ENGINEER
"Three years in the field. The discipline of engineering is not about building things. It is about understanding what can go wrong and designing around it. Mark brought that into every property he has evaluated since."
2013
FIRST REAL ESTATE TRANSACTION. FIRST CLIENT.
"He saw immediately that most agents operated on instinct and narrative. He operated on data. The difference in outcomes was not subtle."
Today
13 YEARS. 300+ CLIENTS. $400M+ IN TRANSACTIONS.
"The market has changed many times since 2013. The method has not."
THE METHOD
Precision at every stage.
01
ANALYZE
Every property Mark evaluates gets the same treatment: price per square foot against comparable sales, days on market context, neighbourhood trajectory, and a clear read on the red flags most people miss. You see the full picture. Before you make any move.
02
STRATEGIZE
First-time buyer. Seasoned investor. Family upsizing. Downsizer cashing out. The situation changes. The commitment to finding the right answer does not. Every strategy is built for the specific person, not a general category.
03
EXECUTE
Offer structure. Negotiation position. Conditions that protect you. Timelines that work. Mark manages every variable between agreement and closing so nothing falls through at the last minute.

"I run the numbers before you fall in love with the property."
Mark Guirgis, REALTOR® | B.Eng Mechatronics, University of Waterloo
THE FULL STORY
Mark Guirgis grew up with one conviction. Every problem has a measurable answer. You just have to ask the right questions and look at the right data.
He graduated from the University of Waterloo's Mechatronics Engineering program in 2010. Spent three years building systems where precision was not optional. Where the cost of guessing was real.
Then real estate happened. Not by accident. By obsession.
He saw what was missing. Buyers and sellers were making the largest financial decisions of their lives guided by instinct, narrative, and hope. The numbers existed. The discipline to use them did not. Mark brought that discipline with him when he made the switch in 2013.
Since then he has worked with buyers and sellers across York Region and the GTA. First-time buyers who needed someone to make sense of an overwhelming market. Growing families trading up to the next chapter. Investors who needed the math to work before anything else. Downsizers who spent decades building equity and needed someone who would protect every dollar of it.
What stays the same across all of them: the numbers come first. Every time.
Mark lives in York Region. He knows its communities the way you know a place you have chosen to build your life in. Not from a map, but from years of transactions on its streets, in its neighbourhoods, at its price points.
He brings the same rigour to a $600,000 condo as he does to a $10,000,000 estate. The property changes. The standard does not.
Every client gets one thing above everything else. A straight answer to the question that actually matters: is this the right move?
WHAT CLIENTS SAY
The proof is in the results.
"I kept hearing 'trust your gut.' Mark showed me the actual numbers instead. I walked into the offer knowing exactly what I was buying. That's all I needed."
Sarah K. · North York
"Eight months with another agent. Six weeks with Mark. Done."
David R. · Richmond Hill
"He passed on two properties that looked great on paper. The one we bought has performed exactly as he projected. I've sent three people to him since."
James T. · Vaughan
