Petrina was born in Wells, British Columbia and spent her early years living in various communities across Canada. Settling in South Langley on a 5 acre hobby farm with her family, she cultivated a deep appreciation for rural life before eventually moving to Vancouver.

Petrina’s dedication to public service and community engagement became evident through her tenure on Langley Township Council, where she was first elected in 2014 and subsequently re-elected in 2018, serving until November 2022. While on Council, she actively participated in various task forces and committees, including as the Township appointee on the City of Langley‘s Homelessness Task Force, and as a member of the Langley Supportive Housing Community project (BC Housing/Stepping Stone), demonstrating her commitment to addressing pressing societal issues. She also served as a representative on the Canadian Pacific Community Advisory Panel, Fraser Health Municipal Regional Panel, and the Township of Langley’s Tree Protection Advisory Committee.

Petrina's focus is enhancing environmental protection, access to affordable housing, supporting seniors to comfortably age in place, expanding transportation options to meet the needs of our growing population, and bolstering infrastructure with additional schools and hospitals.
