Erin joined O’Neill Associates in May 2019 as a Summer Student, and returned as a Placement Student in September 2019 before finally joining the team as an Associate Lawyer in November 2020. Erin has always had her sights set on working as a labour and employment lawyer. Erin graduated from the Bora Laskin Faculty of Law where she was awarded a number of prestigious scholarships and awards for her academic achievements, including First Class Standing, Dean’s Honour Roll Prizes for ranking second in her class, and the Course Prize for the highest mark in Evidence Law. During law school, Erin was heavily involved with the school’s Labour Law Association, holding both Vice President and President roles. Before completing her law degree, Erin completed a Bachelor of Commerce in Business Management with a Major in Law and Business where she focused her studies on workplace law and economics. Erin was also a competitive member of the debate team for all of her academic career leading up to law school, taking home her first debate trophy at only 12 years old.

Growing up in Kenora and Thunder Bay, Erin understands what it’s like to live and work in Northwestern Ontario. Prior to law school, Erin worked full-time for a not-for-profit organization that was devoted to studying and improving the labour market conditions in Northwestern Ontario. In that capacity, Erin travelled to communities throughout the area to speak with business owners and employees about the difficulties they faced in working and running businesses in the North. Erin’s personal, professional and academic history have all helped her develop a deeper understanding of employment and human rights issues faced by individuals and employers in the region. She puts this background to good use in her legal career.

In her spare time, Erin makes the most of the outdoors, even in the face of Thunder Bay’s infamous six (or more) months of winter. Erin’s hobbies include downhill and cross-country skiing, snowshoeing, sailing, and hiking. She also devotes much of her time to volunteering with local animal rescues and is usually ready at any time to show you pictures of her latest foster animals.

Rosanne Stasiewicz at one time last year decided to retire from O’Neill Associates, only to learn that she missed the clients and her co-workers. She comes into the office once a week to continue marketing duties for the firm, and basically parachutes into any job where she is needed.

She is on the Fundraising Committee for a charity she deeply believes in – PRO Kids.

Rosanne is known for her wicked sense of humour (a product of her environment, she claims) and her creativity in finding resourceful solutions to any problem. Her professionalism, dedication, and approachability are the embodiment of O’Neill Associates.
