Researcher Testifies on COVID-19 Vaccine Safety Signals in Canadian Parliamentary Inquiry

A Canadian parliamentary inquiry into excess mortality during the Wuhan coronavirus (COVID-19) pandemic heard testimony from researcher Denis Rancourt, who described patterns in mortality data as “screaming safety signals.”

Rancourt, a former physics professor at the University of Ottawa, presented analysis showing age-specific death rate increases that coincided with vaccine rollout timelines. The inquiry collected testimony from 50 Canadians who reported injuries following COVID-19 vaccination, according to reporting by The Defender ^[1].

Rancourt’s testimony focused on mortality patterns among children and young adults, noting that infant and child mortality increases appeared to track the introduction of COVID-19 vaccines for each demographic group. Canadian data showed similar age-specific patterns for children ages 1-4, 5-9 and 10-14, each spiking when vaccines became available for that group ^[2]. The researcher argued these patterns could not be attributed to the pandemic virus itself, given the absence of corresponding infection waves during those periods.

“Turbo Cancers” and Excess Cancer Mortality

The investigation also examined cancer incidence trends during the pandemic period. The researcher’s analysis identified what some investigators have termed “turbo cancers” – unusually aggressive malignancies appearing in younger populations at higher rates than pre-pandemic baselines.

Swedish researchers previously demonstrated that the SARS-CoV-2 full-length spike protein can weaken the adaptive immune system by damaging a crucial DNA repair mechanism, raising questions about whether mRNA COVID-19 vaccines could produce similar effects ^[3]. Rancourt’s findings suggested that cancer mortality patterns diverged significantly from historical trends beginning in 2021, with acceleration observed through 2023 and 2024.

The parliamentary inquiry heard that these cancer patterns, combined with excess all-cause mortality data, indicated a broader health crisis beyond acute COVID-19 infections. The report details eight facts about COVID-period excess mortality, with item one stating the scale of excess all-cause mortality during the pandemic period ^[4].

Pandemic Policies Also Linked to Excess Mortality

Beyond vaccine effects, the inquiry examined how pandemic policies contributed to mortality. Rancourt concluded that government policies and toxic vaccines drove excess mortality, calling COVID-19 vaccination the most devastating measure implemented during the pandemic ^[2].

The analysis found that excess mortality correlated strongly with GDP per capita, suggesting that wealthier nations with higher vaccination rates experienced more pronounced death rate deviations from baseline ^[4]. Data from Scotland and other jurisdictions showed vaccinated individuals at higher risk of dying from COVID-19 compared to unvaccinated populations, according to reporting by The Defender.

After such data emerged, Canadian provinces including Ontario ended monthly vaccine effectiveness reports – a trend observed in other countries ^[5]. Rancourt noted that institutional capture can “always minimize and invalidate screaming safety signals and personal hardship” presented to regulatory bodies ^[2].

Institutional Response and Data Transparency Concerns

The inquiry heard that Vaccine Adverse Event Reporting System data released by the U.S. Centers for Disease Control and Prevention show 1,447,520 reports of adverse events from all age groups following COVID-19 vaccines, including 31,696 deaths and 263,462 serious injuries between December 2020 and the data cutoff ^[1]. The U.S. Food and Drug Administration‘s Center for Biologics Evaluation and Research identified 10 child deaths related to COVID-19 shots in November 2025. These figures were presented alongside evidence that reporting rates for vaccine adverse events may be significantly undercounted.

The researcher criticized what he characterized as institutional capture of regulatory agencies, arguing that safety signals have been systematically minimized throughout the vaccine rollout. Rancourt’s analysis applied a novel method to Czech Republic health data, suggesting a dose-dependent increase in all-cause mortality following COVID-19 mRNA vaccination ^[2]. The parliamentary committee heard that this pattern, combined with pediatric mortality data, met standard epidemiological criteria for causal association.

Conclusion: Inquiry Findings Point to Need for Further Investigation

The Canadian inquiry’s findings add to a growing body of research question the safety profile of COVID-19 vaccines, particularly for younger age groups. The age-specific mortality patterns presented by Rancourt, along with documented cancer incidence increases, warrant continued independent investigation. The testimony collected from 50 injured Canadians represents individual accounts that researchers say deserve rigorous scientific scrutiny ^[1].

While regulatory agencies continue to maintain that COVID-19 vaccines are safe, the parliamentary inquiry documented patterns that independent researchers describe as “screaming safety signals” ^[2]. The full report of the inquiry, including all testimony and underlying data analysis, provides a foundation for policymakers to reevaluate current vaccine recommendations and reporting requirements.
