Canada's Military Police Complaints Commission releases Major Cristian Hiestand Public Interest Investigation

Tim Dunne

The previous issue of The Observatory described the tragic suicide of RCAF flying instructor Major Cristian Hiestand.

On 25 November 2021, military police (MP) at Canadian Forces Base Moose Jaw received a complaint that the Complainant (identified as “C”) was twice sexually assaulted by her former boyfriend, Major Hiestand, a Royal Canadian Air Force flight instructor. MPs with the Canadian Forces National Investigation Service (Western Region) arrested and charged Major Hiestand with two counts of sexual assault.  On 17 January 2022 he died by suicide.

His mother and sister filed complaints with the Military Police Complaints Commission alleging that the military police investigation was flawed, that investigators did not interview Hiestand before laying charges and failed to gather or consider evidence such as relevant text messages. Surprisingly, a former MP who served at the military police detachment that handled Hiestand's case a filed a third complaint alleging:

  1. A warrant officer failed to ask the complainant whether she preferred to be interviewed by a female officer.
  2. The warrant officer made an unprofessional remark about why the complainant had not gone to the local civilian police instead.
  3. A sergeant returned to assist with the investigation while allegedly off duty and intoxicated.
  4. Inexperienced military police members were assigned to conduct the interview and take notes.
  5. The victim interview was not audio- or video-recorded even though recording equipment was available.
  6. An unidentified support person was allowed to sit in on the interview before being properly identified later.  

On 21 November 2022, almost exactly a year after his death, the MPCC launched a public interest investigation into these complaints and others about how the case was initially handled by a local detachment.  

The MPCC’s review focused on whether the military police conducted an impartial and thorough investigation, including appropriate evidence collection and procedural oversight. Both MPCC’s reports, released 4 February 2026 by Chair Tammy Tremblay, found significant shortcomings in the military police’s handling — describing the investigation as rushed, affected by “tunnel vision” or confirmation bias, seriously flawed and characterized by “undue haste,” and inadequate investigative rigor. It concluded that key investigative steps were missed, such as pursuing relevant witness interviews and properly evaluating evidence before charging, and it called attention to supervisory failures. The MPCC also recommended reforms to improve accountability and investigative standards, including greater consultation with prosecutors in sensitive cases.[1]  

The report found that investigators prematurely formed the belief that a sexual assault had occurred and focused primarily on evidence supporting that conclusion while failing to adequately pursue potentially exculpatory information.

For example, “One of the significant failings in the CFNIS investigation was the lack of systemic examination of key text messages, despite investigators having access to them as of the night of November 29, 2021. 

“[O]n the night of November 29, 2021, at 22:00 hrs, MCpl ***** began downloading the contents of C’s cell phone via a Data Pilot device. Her Security and Military Police Information System (SAMPIS) notes indicate the process took some six hours, completing at 04:00 hrs on the morning of November 30, 2021. As per the disclosure received by the MPCC regarding this information, the text messaging information alone resulted in 1,299 pages of data. Regarding the messages which pertain solely to exchanges with Maj Hiestand, the Forensic Report prepared by Tech Services on January 18, 2022, indicates the extremely high volume of information that was extracted: 121 calls and 7,363 texts.

“MCpl ***** admitted in her interview with PS to conducting only a “cursory” five-minute review of the text messages on the night of November 29, 2021, prior to downloading the data into the Data Pilot.

“MCpl ***** described accessing specific text messages to bolster her grounds for arrest, yet her notebook entries do not reflect this.”[2]

Major Hiestand was given an opportunity to provide a statement to investigators but declined to do so on legal advice. The MPCC determined that investigators nonetheless had an obligation to continue gathering and assessing all available evidence before recommending charges. The report criticized investigators for not interviewing several potentially important witnesses, failing to fully analyze text messages and digital communications, and neglecting to adequately examine contextual evidence relating to consent, intoxication, and the interactions between the complainant and Hiestand before and after the alleged incident. The Commission also found that forensic evidence had not yet been fully processed when the decision to arrest and charge was made.

The MPCC further identified deficiencies in supervisory oversight and case management within the CFNIS. Supervisors failed to ensure investigative objectivity, did not sufficiently challenge assumptions made by investigators, and allowed the case to progress without confirming that investigative standards had been met. The report stated that this lack of oversight contributed to tunnel vision and a “rush to judgment,” undermining both fairness and public confidence in the military justice system.
 
While the Commission did not conclude that the investigation directly caused Major Hiestand’s suicide, it acknowledged the profound personal and professional consequences of the arrest and charging process. The report emphasized that investigators must remain aware of the serious impacts criminal allegations can have on accused persons, complainants, families, and military communities. The MPCC stressed that balanced and thorough investigations are essential not only for accountability and victim support, but also for protecting procedural fairness and the integrity of the justice system.
 
The investigation resulted in 13 recommendations directed at improving military police investigative practices, especially in sexual assault cases. These recommendations included enhanced training on confirmation bias and investigative neutrality, stronger supervisory review, improved documentation practices, more comprehensive evidence assessment requirements, and clearer standards governing when charges should be laid. The MPCC also called for measures to reduce tunnel vision and reinforce investigators’ obligations to seek both inculpatory and exculpatory evidence.
 
The final report framed the Hiestand case as a cautionary example of how investigative bias, insufficient oversight, and premature decision-making can compromise justice outcomes. It urged the Canadian military policing system to adopt reforms aimed at restoring confidence, improving professionalism, and ensuring fair, evidence-based investigations in future cases.
 
“I am troubled by the CFPM’s weak and dismissive response to recommendations grounded in clear and serious investigative failings,” Chair Tammy Tremblay commented. “These recommendations were designed to strengthen investigative experience, procedures, supervision, and case management in sexual assault investigations, all of which were plainly deficient here. Yet, in response to 13 recommendations, none were accepted by the CFPM. Despite the extensive problems documented in this report, the CFPM was unable to acknowledge the need for improvement in any of the areas addressed.
 
 “Given the facts of this case, such complacency is astonishing. The family, and indeed the members of the military police, deserve better. Without a willingness to confront these shortcomings and commit to meaningful change, the systemic issues highlighted in this investigation will remain unaddressed, to the detriment of future military police investigators, complainants and the integrity of military policing as a whole. It is imperative that the CFPM swiftly implement these recommendations to ensure that all future investigations are conducted to the high standards of rigour, impartiality, and professionalism that Canadians expect and that members of the Canadian Forces deserve.”[3]
