Canada's Bill C-223 Advances: Parental Alienation Claims Would Be Banned, Family Violence Screening Required

Bill C-223, the Keeping Children Safe Act, passed second reading in Parliament on February 4, 2026, and now sits before the Standing Committee on Justice and Human Rights for review. If enacted, this legislation will fundamentally change how Ontario and all Canadian family courts handle parenting disputes by prohibiting courts from considering parental alienation as a factor in determining parenting arrangements. The bill also mandates that all family lawyers screen clients for family violence before proceeding with any custody-related matter.

What Bill C-223 Changes in Canadian Family Law

Bill C-223 introduces four major changes to how Canadian courts determine parenting arrangements. First, judges would be explicitly prohibited from relying on parental alienation or similar theories when making decisions about children. Second, every family lawyer in Canada would be required to screen all clients for indicators of family violence before commencing proceedings. Third, courts would be barred from applying presumptive equal parenting time in any case where family violence is present or alleged. Fourth, children would receive expanded opportunities to express their views directly to judges rather than through intermediaries.

The legislation responds to concerns raised by family violence experts and child welfare advocates who argue that parental alienation theory has been misused to dismiss legitimate abuse allegations. Research published by the National Family Violence Prevention Network in 2024 found that parental alienation claims were raised in 43% of contested parenting cases involving documented abuse histories.

How Ontario Courts Currently Handle Parental Alienation Claims

Ontario courts currently have discretion to consider parental alienation when determining parenting arrangements under the Divorce Act and the Children's Law Reform Act. The 2021 amendments to the Divorce Act already require courts to consider family violence as a primary factor, but judges retain authority to weigh claims that one parent has attempted to damage the child's relationship with the other parent.

Under current Ontario law, judges apply a best interests of the child analysis governed by section 16 of the Divorce Act. This analysis includes considering family violence (section 16(3)(j)) and the willingness of each parent to support the child's relationship with the other parent (section 16(3)(c)). Bill C-223 would remove this second consideration when it manifests as a parental alienation claim.

Ontario Superior Court Justice Donna Martinson noted in a 2023 decision that Canadian courts have been increasingly skeptical of parental alienation theory, citing concerns that it was developed without peer-reviewed validation and has been rejected by the American Psychological Association for inclusion in the DSM-5.

The Family Violence Screening Requirement

Bill C-223's mandatory screening provision would require all family lawyers to conduct family violence assessments with every client before filing or responding to any parenting-related application. This represents a significant shift from current practice, where screening is recommended but not required by provincial law societies.

The Law Society of Ontario's current Rules of Professional Conduct encourage but do not mandate family violence screening. Under Bill C-223, Ontario family lawyers would face potential regulatory consequences for failing to screen clients, though the specific enforcement mechanism remains to be clarified during committee review.

The Family Law Rules currently require parties to complete a Form 35.1 Affidavit addressing family violence allegations, but this self-reporting mechanism places the burden on litigants rather than their lawyers. Bill C-223 shifts responsibility to legal counsel to proactively identify safety concerns.

Impact on Equal Parenting Time Presumptions

Bill C-223 directly addresses the equal parenting time provision added to the Divorce Act in 2021. Section 16(2) currently requires courts to give effect to the principle that a child should have as much time with each parent as is consistent with their best interests. Bill C-223 would create an explicit exception: when family violence is present or alleged, courts cannot apply any presumption of equal parenting time.

Ontario family courts already consider family violence when determining parenting schedules, but Bill C-223 would formalize this as an automatic exclusion rather than a discretionary factor. Statistics Canada data from 2024 indicates that approximately 31% of contested parenting cases in Ontario involve family violence allegations.

Children's Voices in Court Proceedings

The legislation expands opportunities for children to express their views directly to judges rather than through Office of the Children's Lawyer reports or expert assessments. Under current Ontario practice, judges rarely meet directly with children. The Children's Law Reform Act requires courts to consider children's views but does not mandate direct judicial interviews.

Bill C-223 would require courts to provide children with the opportunity to speak directly to a judge when they express a desire to do so. This aligns with Canada's obligations under the United Nations Convention on the Rights of the Child, which Canada ratified in 1991.

Practical Takeaways for Ontario Families

  1. Parents currently facing parental alienation allegations should gather documentation of the factual circumstances underlying these claims before Bill C-223 potentially passes, as the evidentiary framework may shift.

  2. Anyone experiencing family violence should know that Bill C-223 would require their lawyer to screen for safety concerns proactively, potentially accessing support resources earlier in the legal process.

  3. Parents seeking equal parenting time should understand that if abuse allegations are present, Bill C-223 would remove any presumptive entitlement to 50/50 schedules regardless of other factors.

  4. Children over age 12 who wish to speak directly to a judge about their preferences may soon have an explicit right to do so rather than relying on judicial discretion.

  5. Family lawyers across Ontario should begin preparing screening protocols now, as Bill C-223 may pass committee review and receive Royal Assent within 2026.

Frequently Asked Questions

When would Bill C-223 take effect if passed?

Bill C-223 must complete committee review, third reading, Senate review, and Royal Assent before becoming law. If the Standing Committee on Justice and Human Rights reports the bill back by June 2026, implementation could occur by late 2026 or early 2027, with a 180-day transition period for lawyers to develop screening protocols.

Can courts still address situations where one parent discourages the child's relationship with the other?

Yes. Bill C-223 prohibits courts from considering parental alienation as a labeled theory but does not prevent judges from examining specific behaviors. Courts would still assess whether a parent supports the child's relationship with the other parent under section 16(3)(c) of the Divorce Act based on documented conduct rather than alienation frameworks.

Does this bill apply to already-decided parenting arrangements?

Bill C-223 would apply prospectively to new applications filed after its effective date. Existing court orders would remain in effect. However, variation applications filed after the effective date would be subject to the new provisions, potentially affecting how courts reassess ongoing parenting disputes involving alienation claims.

What qualifies as family violence under the bill?

Bill C-223 adopts the family violence definition from section 2 of the Divorce Act, which includes physical abuse, sexual abuse, threats, harassment, stalking, failure to provide necessaries, psychological abuse, financial abuse, and killing or harming animals. This definition already governs Ontario family proceedings under the 2021 amendments.

How would the screening requirement work in practice?

Family lawyers would be required to use validated screening tools to assess family violence indicators before filing any parenting-related application. The Law Society of Ontario would likely develop practice guidelines specifying approved screening instruments. Lawyers who fail to screen could face professional conduct complaints.
