Adoption Information Disclosure Act
Canadian law regarding adoptions

The Adoption Information Disclosure Act, formally An Act respecting the disclosure of information and records to adopted persons and birth parents, also known as Bill 183, is an Ontario, Canada, law regarding the disclosure of information between parties involved in adoptions.
The Act was passed by the Legislative Assembly of Ontario in 2005 and put into force on September 17, 2007. Significant sections of it were quashed just two days later in a ruling by Judge Edward Belobaba of the Ontario Superior Court.
On November 13, 2007, the Ontario government announced that instead of appealing Belobaba's decision, it would opt to amend the act to contain a universal disclosure veto. It accordingly introduced the Access to Adoption Records Act on December 10, 2007, which passed third reading in May 2008 and took effect in September 2008.
Background
From 1927 until the mid-1980s, certain measures existed in Ontario to preserve anonymity between birth parents and adoptees; this was consistent with adoption practice elsewhere in Canada and the United States at that time.
The practice was reduced but not eliminated for current adoptions, but there remained the question of what to do with existing adoption records: how does the right to information for either party compare with the obligation of honouring past commitments to privacy?
Adoptees and birth parents could apply to be put onto the government-run Adoption Disclosure Register, but the process was long, the resources for active searches for birth relatives were limited, and success was not guaranteed.
NDP MPP Marilyn Churley introduced several bills into the Legislative Assembly starting in the late 1990s. Her strong stance for open records was personally motivated, as she had placed a child for adoption years earlier and was later reunited with him.

Why this record matters
The phrase “canadian law regarding adoptions” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q4684569. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2005, 2007, 2008 and 1927.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
