In Ont., Mercer Reformatory records were denied under the YCJA—but teens 16–17 weren’t considered “youth offenders” then. We appealed—and won. Orders PO-4749, PO-4750 & PO-4751 force a new access decision.

In 1905 in Ontario, a little girl was placed out for the first time. J.J. Kelso’s vision was to rescue children from unworthy families and give them “safe homes.”
But that vision fell short — she was shuffled through home after home, only breaking free by marrying.

🧵The Andrew Mercer Reformatory was one of many carceral institutions in Ontario that imprisoned over 20,000 women and girls.

We’ve seen Children’s Aid Society (CAS) and Mercer records of a mom jailed in 1911 with five kids—all “placed out.” One son, indentured, was denied his earnings by Fort William CAS when he turned 18 in 1922. He hired a lawyer. How much did CAS steal from those who had no power?

This is an extremely tragic story that begins in the 1930s. It’s unbelievable what happened to this family — the children, the foster care system, the adoptions that followed and Ontario Training School. Make maters worse, discovering your grandmother was at Mercer there during the 1948 riot.

This fabric will be joined with printed newspaper clippings from the June 1948 Mercer prison riot — the second month my 17-year-old grandma arrived there.

Thank you for letting me know! It’s likely set to private then for only FB friends. Sorry about that. It was a video of an array of fabric plus newspapers images of the riot.

Obscured behind adoptees’ records and adoption stats are likely many girls labeled as "delinquents" or wards of the CAS — committed to Ontario Training Schools (OTS) or placed on probation until age 21 (later reduced to 18).
The image below shows the scale of girls under OTS wardship only.

Wards of the CAS were almost never named in the press — but 13-year-old Lillie was.

Little is known about her, but we do know she arrived at the Industrial Refuge in the west wing of the Mercer Reformatory.
Her charge? “Immoral conduct.”

Like so many others, Lillie’s voice was lost in the records.

According to Ont Agricultural College, in 1934 L. Payne, a grad, published a book: Bread and Water Diets of Prisoners Found Inadequate. In 1947, K. Sandford documented punishment in the dungeon and the bread-and-water diet at Mercer. This raises the question: when was this punitive practice ended?

Several access requests for Mercer records were denied under the YCJA. In this case (age 17, 1931), she was sentenced as an adult—yet the records are now denied as if she were a youth? Really? We sought help. 👇

A 1948 report from the Ontario Training School (OTS) for Girls reveals that 7 pregnant girls were transferred to other carceral institutions — including MATERNITY HOMES — upon admission.

There’s a clear pipeline of control linking childhood labels, eugenics-based schooling, training schools, and finally incarceration at Mercer. This thread unpacks that system. 🧵

On this day, Aug 28, 1880: The first two women were incarcerated at Mercer. Over the next 80 years, more than 20,000 women and girls—many of them pregnant—were held there before it closed in 1969.

A 13-year-old girl, labelled a 'prostitute.' In the 1950s, she would have been incarcerated in the west wing of Mercer, designated as the Ontario Training School for Girls Toronto. Many of the girls were pregnant.

Georgina Brooks, a Black woman incarcerated at Mercer, was a victim of systemic racism and institutional neglect. She couldn’t save herself—and like many others, she died behind the walls of the Mercer Reformatory. 1/2

A sobering reminder: old gendered and moral laws are gone, but control persists in subtler, bureaucratic forms today.

Lilly Davey (aka #PearlHart) of Lindsay, Ont., endured an abusive childhood and saw her mother brutally degraded by four men. In 1888, at 17, she was jailed at Mercer for vagrancy—1 year, 10 months, 28 days.

On this day, May 9, 1888, Lillie was arrested in Hamilton, Ontario. She would later become known as a notorious female bandit of the Wild West, though there was little discussion of the severe abuse she suffered in childhood.

Only recently have some adoptees begun uncovering their hidden carceral birth histories, but many— including descendants—remain unaware. This article critiques 'post-adoption' and highlights the ongoing injustices.

"In short, our penal machinery seems to recruit its victims from among those that are fighting an unequal fight in the struggle for existence."
Since its publication in 1890, has anything truly changed for these victims worldwide?

Newly uncovered yesterday: the deaths of Irene Antone and Victoria Conlis at Mercer. Thanks to @lauren___mullen
—always one step ahead—we also now know about Mary Barnes, who died at the Concord Jail Farm. These cases expose long-overlooked histories of women in custody.
