Another class-action specialist, in the Montréal office, Anne Merminod is a recent addition to Benchmark and a quickly rising future star who is developing her own devoted fan base among peers and clients. Merminod was part of a team that led the successful defense of IIROC in a class-action lawsuit over loss of personal information at the merit stage.



Michael Byers of Toronto securities-focused boutique Crawley MacKewn Brush is the firm’s most recent nominee to Benchmark’s future star status and has been noted to have taken a more active role, independently as well as in tandem with name partners, in some of the firm's most important mandates. Kate McGrann, a partner quickly establishing herself alongside her more senior peers at the firm, has developed a well-earned reputation as a go-to for inquiries. She was appointed co-lead counsel to the Ontario Long-Term Care COVID-19 Commission with a mandate to investigate the spread of COVID-19 within long-term care homes and to recommend ways to prevent a future problem. Prior to that, McGrann had been leading a major municipal inquiry. Clarke Tedesco regularly appears on some of the firm’s most high-stakes mandates with all three name partners, occasionally in a semi-lead role. In one such case, Tedesco appeared as second chair in prosecuting a claim for $700 million in damages arising out of a failed joint venture between a real estate developer and the Ottawa Senators organization.

Ryan Phillips focuses on commercial and transactions, construction, energy, government and regulatory, and insurance. He also has unique experience with professional negligence defense of large law firms.



Laura Bevan in the Vancouver office of Western Canada powerhouse Lawson Lundell is a peer favorite. “She is fantastic," extols one peer. "I have a lot of time for her. She is a real force to be reckoned with, [she is] very effective, gets good mandates.” One such mandate is Bevan’s engagement on behalf of Gateway Casinos, a participant in the gaming sector, in a broad and high-profile review of money laundering within several key industries in British Columbia. Also in Vancouver, Lauren Cook is primarily in the regulatory world, representing companies that are being investigated and potentially prosecuted.

Julien Archambault of Montréal litigation boutique LCM focuses on construction litigation as well as insolvency. Archambault’s keen acumen with construction litigation is owed to an understanding of its intricate issues, a knowledge that extends even beyond legal issues and has roots in a fascination from childhood. Archambault and his team represented Hydro-Québec in a file against a multi-million-dollar claim by Transelec relating to construction work for the addition of a transformer to a substation. He and his team also represented Château B'Nai Brith, the promoter of a multi-floor senior residence, against a multi-million-dollar claim by the general contractor relating to construction of said residence.

In a unique case exemplifying an intersection of these practices, Scott is representing Guestlogix in a pending appeal before the Ontario Court of Appeal regarding the intersection of releases contained in plans of arrangement under CCAA and employment law termination obligations.



Jesse Gardner of the Toronto office of two-pronged construction litigation powerhouse Singleton Urquhart Reynolds Vogel was part of the firm team representing the City of Ottawa in a matter concerning allegations of delays and service problems associated with the construction of the City’s $2.1 billion light rail transit system.

One peer confirms, “We were working on something together that involved some Competition Act issues, and he was great. I view him as having a lot of headroom for growth in this market.”



Tupman & Bloom’s Arieh Bloom is a Toronto-based commercial litigator with a specialty niche in trust and estates work. One of the younger litigation stars among the city’s legal community, Bloom has already made quite an impression. “Arieh Bloom is this Orthodox whiz-kid from Nebraska and is already knocking it out of the park here,” marvels a Bay Street peer. “For his vintage, he has the most encyclopedic knowledge of trust and estates work. He actually teaches judges about the passage of wills practice, and he does it with a personality.” Bloom’s background as a CPA enhances his practice, and his recent work includes bringing oppression claims on behalf of an estate trustee over the voting rights of the control preferential shares of a family business, and bringing an application for the recognition of a cross-border guardianship application.



Cory Wanless was welcomed into the partnership of Toronto plaintiff boutique Waddell Phillips in 2021 and has built a relatively new practice that focuses on human rights and corporate and police accountability.
