A case that has gripped the US
Lindsay Clancy, a Massachusetts mother charged with killing her three young children in 2023, is currently standing trial in the United States. Her defence has centred on a claim of insanity, arguing she was not criminally responsible due to a severe mental health crisis at the time of the deaths. The case has drawn intense media coverage and reignited debate over how the justice system treats parents, particularly mothers, who kill their children while experiencing a mental health collapse.
But if a similar case unfolded in Canada, the legal path could look very different, starting with the charge itself.
Canada's unique infanticide law
Unlike the United States, Canada's Criminal Code contains a specific offence called infanticide, laid out in Section 233. It applies narrowly: a mother can be charged with infanticide, rather than murder, if she causes the death of her child under the age of one, and if her mind was disturbed at the time because she had not fully recovered from giving birth or from the effects of lactation.
The offence carries a maximum sentence of five years, far lower than the mandatory life sentence attached to a murder conviction in Canada. Critics have long argued the law is medically outdated, since it ties criminal responsibility to childbirth and breastfeeding rather than a broader understanding of postpartum mental illness. Supporters counter that it exists precisely because the justice system recognizes these cases are fundamentally different from other homicides and deserve a different legal lens.
Not criminally responsible: the other Canadian route
Even outside the infanticide provision, Canada has a separate and broader legal mechanism that could apply in a case like Clancy's: a verdict of not criminally responsible on account of mental disorder, often shortened to NCRMD. This is roughly analogous to an insanity defence in the US, but the process afterward diverges sharply.
In Canada, a person found NCRMD is not simply acquitted and released, nor automatically imprisoned. Instead, their case goes to a provincial review board, which can order a detention in a secure psychiatric facility, conditional discharge with treatment requirements, or an absolute discharge, depending on the ongoing risk they pose to public safety. That decision is revisited regularly, sometimes annually, rather than being fixed by a single trial outcome.
Why legal experts are drawing the comparison
Legal scholars in Canada have pointed to the Clancy case as a chance to explain how the two systems weigh the same underlying question: what happens when a parent's mental state at the time of a killing was severely compromised. In the US system on display in the Clancy trial, the outcome hinges heavily on a binary insanity verdict decided by a single jury. In Canada, the combination of the infanticide provision and the review board process for NCRMD findings creates more graduated options, built around ongoing psychiatric assessment rather than a one-time legal determination.
That does not mean the Canadian approach is free of controversy. Advocacy groups have called for reform of the infanticide law for years, arguing it should be replaced with a framework that reflects current medical understanding of postpartum psychosis and depression, rather than a provision written decades ago.
