Robyn Blumberg is an associate in the Construction Law Group, where her practice primarily focuses on helping construction industry clients navigate the civil litigation and dispute resolution process.  Robyn has regularly appeared on construction lien and other matters before the Ontario Superior Court of Justice, and she also has experience appearing before the Ontario Court of Justice on municipal licensing and standards issues.

Robyn prepares materials and assists clients on a wide variety of applications and motions in commercial and construction litigation disputes. She also has experience drafting and reviewing construction contracts prior to the commencement of a project, and she supports clients with contract interpretation once a dispute arises.    

Robyn has advised owners, contractors, and subcontractors on both commercial and residential construction issues, including bidding and tendering, deficiencies, delay, construction liens, breach of contract, and breach of trust.  

Prior to joining Cassels Brock as an associate, Robyn was both a summer and articling student with the firm. Robyn completed her J.D. at Osgoode Hall Law School where she was awarded the Ronald J. Rolls ‘58 Q.C. Prize for the highest standing in Civil Procedure. During her studies at Osgoode, Robyn participated in the Innocence Project, focused on investigating suspected cases of wrongful conviction and, where it appears an accused has been wrongfully convicted, seeks proof of innocence. In the summer of 2013, Robyn was instrumental in coordinating the 34th Annual Intensive Trial Advocacy Workshop (ITAW). Following completion of the program, Robyn continued her work with ITAW as a Research Assistant, investigating and reporting on factors contributing to persuasiveness in trial advocacy.

Robyn also spent a semester studying abroad at the University of Hong Kong.

Robyn holds a Bachelor of Arts undergraduate degree (magna cum laude) with a major in International and Global Studies and minors in Economics and Legal Studies from Brandeis University in Waltham, Massachusetts. Prior to becoming a lawyer, Robyn worked as a Digital Associate at a global media agency in New York City.
