At Sienna, we empower our team members across Ontario, British Columbia, Saskatchewan and Alberta to help our residents live the life they desire and deserve. Our purpose is simple: to cultivate happiness in daily life!

What Sienna Offers: We aspire to cultivate an environment and culture where team members feel valued, heard and empowered to do meaningful work. This includes continuous learning and growth, so you have the skillset needed to succeed and take on new challenges.

What You’ll Be Doing:

The Summer Internship at Sienna Senior Living provides students with a hands-on opportunity to gain meaningful experience within the seniors living and healthcare sector. Interns will support key business functions such as operations, human resources, finance, or resident experience, contributing to projects that enhance the quality of care and services across Sienna’s communities.

Throughout the program (June 1, 2026 to August 14, 2026) interns will collaborate with cross-functional teams, assist with day-to-day operations, and participate in strategic initiatives that drive organizational performance. This role offers exposure to a dynamic, mission-driven environment focused on enriching the lives of seniors, while developing professional skills in communication, problem-solving, and teamwork.

By the end of the internship, participants will have gained practical industry knowledge, built valuable relationships, and developed a deeper understanding of how a leading Canadian seniors living organization operates.

How You’ll Succeed:

  • Support in preparation of reports, presentations and documentation.
  • Assist with ongoing project work as assigned.
  • Conduct research and compile data as required.
  • Support administrative and operational activities.
  • Maintain organized records and files.
  • Provide planning support for our Shared Support Office engagement events.
  • Participate in meetings and contribute ideas and suggestions.
  • Collaborate with cross-functional teams as required.

Who you are:

  • Student currently enrolled in a post-secondary program in a relevant field such as Business, Health Care, Finance or Marketing.
  • Strong critical thinking and problem-solving skills.
  • Excellent interpersonal skills.
  • Ability to work independently and collaboratively in a fast-paced environment.
  • Strong organizational and time management skills.
  • Eagerness to learn and take initiative.
  • Experience working with Microsoft Suite (Word, Outlook, Excel, PowerPoint, etc.)

What you need to know:

  • Location: Markham Ontario
  • Working Arrangement: 100% On-Site
  • Any offer of employment will be conditional upon a criminal background and references check.
  • This posting is for a new position.
  • Sienna Senior Living may utilize artificial Intelligence to screen or assess applicants for this position.


Sienna Senior Living is committed to employment equity, diversity, and inclusion in the workplace. In accordance with provincial regulations, upon request, support will be provided for accommodations throughout the recruitment, selection, and assessment process
