  • You design experiments (DOE), conduct process validation, and document everything thoroughly to meet regulatory expectations.
  • You troubleshoot issues on the production floor—often under time pressure—during tech transfers or commercial campaigns.
  • You Support change control and deviation/CAPA investigations and write clear technical justifications using science- and risk-based approaches.
  • You work with equipment vendors and Maintenance to qualify systems (IQ/OQ/PQ) and optimize equipment performance.
  • You lead or contribute to continuous improvement projects that reduce cost, waste, energy use, and downtime.

Main tasks (in bullet points)

  • Develop and optimize manufacturing processes for drug substance and/or drug product
  • Scale up from lab/pilot to commercial production
  • Create and maintain process flow diagrams (PFDs) and Piping & Instrumentation Diagrams (P&IDs)
  • Write and execute validation and verification protocols (PQ/PV)
  • Perform root cause analysis and implement CAPA
  • Conduct statistical analysis (e.g., control charts, capability, DOE)
  • Implement PAT (Process Analytical Technology) for real-time monitoring
  • Ensure compliance with Health Canada GMP, ICH guidelines, and company SOPs

Expert Opinion

If you’re aiming for a Chemical Engineer (Pharmaceutical transformation processes) role in Ontario, build a strong foundation in mass transfer, thermodynamics, reaction engineering, and statistics, then pair it with GMP and validation know-how. Co-op terms at Ontario manufacturers—like vaccine producers, sterile injectables, or solid dosage facilities—can launch your career. Even one good co-op where you run a small DOE, support a process validation, or complete a cleaning validation study will make your resume stand out.

Consider blending your engineering degree with targeted training: an ISPE course on aseptic processing, a Lean Six Sigma Green Belt, or an ASQ certificate if you’re leaning towards QA/Validation leadership. If you want to sign off on engineering work or aspire to senior technical authority, plan for your PEO licensure pathway early—register as an EIT, and look for supervised engineering experience.

Ontario’s pharma ecosystem is collaborative. Attend events hosted by Life Sciences Ontario or OBIO and ask for informational interviews. Many companies value a practical, hands-on mindset. If you can confidently discuss a time you stabilized a process, improved yield, or fixed a recurring deviation with a data-driven approach, you’ll be in demand.

FAQ

Do I need a P.Eng license to work as a Chemical Engineer in pharma in Ontario?

Not always. Many process and validation roles don’t require you to stamp drawings or take legal responsibility for public safety. However, if your duties involve professional engineering practice as defined by PEO—such as taking responsibility for designs or modifications that affect safety—you will need a P.Eng. Many employers support the EIT to P.Eng pathway, and having a P.Eng can open doors to senior technical and leadership roles. Learn more: https://www.peo.on.ca
