The houses were supposed to belong to seniors. The seniors were the investors.
An Edmonton police investigation alleges Curtis Quigley and Kathleen Treadgold sold promissory notes tied to real estate flips for twelve years. The houses were the story. The seniors who lost their money were the inventory.
Marion was seventy-one when she signed the promissory note on her kitchen table in Kelowna. Eighty thousand dollars. The pen was a Bic from the drawer where she kept the elastic bands and the receipts from Rona. The woman across from her had a juicery downtown. That was part of why Marion trusted her. A person who runs a small business in your town is a person who has to look you in the eye on a Tuesday.
The note said the money would buy a house in Edmonton. A senior's house. The kind of place where the owner had died or moved to care and the family wanted to be done with it. The company would buy the house, fix what needed fixing, and sell it inside ninety days. Marion would get her principal back plus a set return. It was right there on the paper. A number. A date. A promise.
She did not know that the house was not the product.
She was.
I.
The company was called Group Venture Inc. The man behind it, according to court documents, was Curtis Gordon Quigley. The woman who sat with investors and walked them through the paperwork, according to a July 2021 court filing, was Kathleen Treadgold, described there as a "salesperson." She is also the woman who ran Glow Juicery in Kelowna, which closed in January 2020. The couple are both 56. They are charged jointly.
On May 1, 2026, the Edmonton Police Service announced 80 counts of fraud over $5,000 and one count of money laundering against the two of them. The investigation took three years. Detective Linda Herczeg of the EPS financial crimes unit told reporters this was the largest flow of money into a Ponzi scheme she had investigated in her eight years working that file. The Alberta Securities Commission helped. So did FINTRAC, the federal agency that tracks money laundering. So did the Canada Revenue Agency. So did the RCMP.
Police know of 184 investors. Alberta. British Columbia. The United States. Australia. The alleged total loss is $7.8 million.
The allegations have not been proven in court.
A Ponzi scheme is a simple machine. New money pays old money. There is no underlying business generating the returns. The returns are the new investors. When the new investors stop arriving, or the old investors all ask for their money at the same time, the machine stops. Everyone after the stop loses everything. Everyone before the stop got paid with the money of the people after them, whether they knew it or not.
The Edmonton police allege this is what Group Venture Inc. was. A machine dressed as a real estate company.
II.
The pitch was the genius of it.
A real estate flip is a normal thing. People do it. They buy a house, they fix it, they sell it. There are television shows about it. The number Marion was promised was higher than a GIC but not absurd. It was a number that sounded like work. Like someone had done the math on drywall and a new roof and a quick sale and figured out what was left.
The story had a moral shape too. The houses were coming from seniors. Estates. People who needed to move on. The pitch implied that Group Venture was helping families clear properties they could not handle. Marion liked that part. It made the money feel useful.
A promissory note is a piece of paper that says one person owes another person money on specified terms. In a private offering, a promissory note can be a security. In Canada, securities sold to the public have to be registered, or they have to qualify for an exemption, and the people selling them have to be registered too. The Alberta Securities Commission's involvement in the Edmonton investigation suggests that part of the file is about whether any of those rules were followed.
Marion did not know any of this. She knew the woman who sold her the note had a business downtown and a friendly face and a folder of paperwork that looked like the kind of paperwork a real company has.
The cheques came. Quarterly. On time. For years.
That is the part that matters. That is the part the machine is built for.
III.
The math of a long Ponzi is the math of patience.
If Marion put in $80,000 and got a $4,000 cheque every quarter, that is $16,000 a year. After two years she has been paid $32,000. She tells her sister. Her sister puts in $50,000. Marion adds another $40,000 because the first one worked. Now Group Venture has $170,000 from one family and has paid out $32,000 of it back to one of them. The other $138,000 is in the account, available to pay the next quarter's promised returns to someone else.
This is the mechanism. Not growth. Reshuffle. Not yield. The money you put in last, paid back to the person who put it in first, with the operator taking a cut and calling the difference a flip.
The Edmonton police allege the scheme ran from October 2008 to December 2020. Twelve years. Through the 2008 financial crisis. Through the housing booms and the housing slowdowns. Through a global pandemic. The cheques cleared the whole time, until they did not.
Twelve years is a long time for a machine to run. Long enough that the early investors did not just trust the operator. They recommended the operator. They became, without knowing it, the unpaid sales force.
That is how 184 people end up in the file.
IV.
The structure became visible the way these structures always become visible. The cheques stopped.
In December 2020, the alleged scheme collapsed. In 2020, Curtis Quigley was declared bankrupt in British Columbia. The B.C. Supreme Court file shows 72 creditors came forward with claims totaling nearly $26 million.
Read that number again. $26M USD-equivalent (this is Canadian dollars, roughly $19M USD at 2020 rates). The police allege $7.8M in Ponzi losses. The bankruptcy creditors claim nearly $26M. The gap between those two numbers is one of the open questions in the file. Some of the bankruptcy claims may be unrelated business debt. Some may be the same losses counted in a different forum. Some may be investors the police investigation has not yet reached.
Marion's name was on one of those creditor lists. She got a notice in the mail. It was the first time the word "bankruptcy" had entered her kitchen since her husband died.
She read it twice. Then she read the part of the promissory note that talked about what would happen if Group Venture could not pay. She did not understand most of it. She understood that the houses she had been told her money bought were not houses that had ever been in her name.
Her son drove up from Vancouver that weekend. He sat at the same kitchen table where the note had been signed and he did the math out loud, slowly, the way you do when you are trying not to make your mother feel worse than she already does.
The number on the paper said $80,000.
The number coming back said no.
V.
The police investigation took three years after that. Three years to subpoena records, trace bank transfers, interview investors in four jurisdictions, work with FINTRAC on the money laundering count, work with the Alberta Securities Commission on the securities side, and lay charges that would stand up in court.
On May 1, 2026, Curtis Quigley and Kathleen Treadgold surrendered to Edmonton police. Eighty counts of fraud over $5,000. One count of money laundering. They are now in the court process. The allegations have not been proven.
This is what the law looks like when it catches up with a twelve-year machine. It looks slow. It looks like detectives reading bank statements for thirty-six months. It looks like one detective on the courthouse steps explaining to reporters that this was the largest flow of money she had seen go into a Ponzi in eight years on the file.
It does not look like Marion getting $80,000 back.
It does not look like the sister getting $50,000 back.
It does not look like any of the 184 known investors getting whole.
VI.
There is a pattern here that is not specific to this couple or this company. The pattern is the shape of the pitch.
A real-sounding underlying business. Real estate. Senior housing. Something the investor can picture.
A fixed return promised in writing. A promissory note instead of a share. A specific number on a specific date.
A small operator with a local face. A juicery owner. A managing partner. A person who looks like a neighbor, not a Wall Street name.
A long runway of on-time payments before anything goes wrong. The cheques arrive. The trust compounds. The investor's family members get added to the file.
A bankruptcy filing that is the first public sign of the collapse.
A criminal investigation that takes years to surface what the bankruptcy filing made visible.
A list of 184 people who thought they had bought a house.
VII.
Marion is seventy-six now. She still lives in the same place. She still keeps her papers in the same drawer. The promissory note is in there. So is the bankruptcy notice. So is the news article from May where she saw the names again, in print, with the word "charged" beside them.
She reads the article slowly. She gets to the part about the 184 investors and stops. She had not known there were that many. She had thought, somehow, that this had happened mostly to her.
The machine is built for that too. It is built so each mark feels like the only mark. It is built so the woman who sold you the note seemed like she was making time for you alone. It is built so the cheques feel like they came from a house, not from a stranger in another province who has just signed his own note on his own kitchen table.
Marion thought she had bought a house in Edmonton from a senior who needed to sell.
A senior did sell.
Her.
