A serious practice. A genuinely collegial one.
Sullivan Mahoney has been part of the Niagara legal community since 1947. We are full-service by design — meaning our lawyers see complex files, mentor across practice areas, and build careers in one place rather than fragmenting them across firms.
We invest in our people because the alternative is more expensive. That means formal mentorship from year one, an internal CPD program, and partners who treat associates' development as part of their job description.
Compensation and support that lets you do your best work.
Benefits vary by role, but every position at Sullivan Mahoney is built on the same foundation.
Competitive compensation
Salary bands benchmarked against comparable Ontario firms, with merit reviews tied to demonstrable progression — not tenure alone.
Health & wellness
Full extended health, dental, vision, and paramedical coverage from day one, plus an annual wellness allowance.
Hybrid by default
Our offices are designed for the work that benefits from being together; the rest is flexible. No rigid in-office quotas.
Mentorship from year one
Every associate and student is paired with a partner mentor. We protect time for it; it isn't a flyer.
CPD & learning budget
Annual budget for external CPD, conferences, and skills training, plus an in-house program led by the firm's senior counsel.
Parental leave top-up
Top-up to a meaningful percentage of salary for primary and secondary caregivers, regardless of practice group.
We're always interested in hearing from strong candidates.
