Leonard Kalishenko, P.Eng.
Principal
Leonard Kalishenko, P.Eng., has overseen more than 2000 projects and brings more than 35 years of consulting and structural design experience to every engagement. He is a member of the Professional Engineering Associations of Ontario, British Columbia, Saskatchewan, Nova Scotia, New Brunswick, and Manitoba, and remains personally involved as principal from early concepts through construction.
His practice spans multi-storey residential, commercial, institutional, industrial, and renovation work across Ontario and beyond. Clients and builders value a clear load path, practical detailing, and decisive responses when field conditions diverge from the drawings. Leonard’s approach emphasizes early coordination with architects and contractors so structural decisions support schedule and constructability rather than arriving as late constraints.
As the firm’s principal, he sets technical standards for analysis, documentation, and site review, and stays accountable for the quality of advice delivered under the Leonard Kalishenko and Associates name.
