Canadian Nuclear Laboratories (CNL), has witnessed a changing of the guard.
CNL is pleased to announce that it has appointed Joe McBrearty as its new President and Chief Executive Officer (CEO).
McBrearty served as CNL’s Chief Operating Officer (COO) for the past year and will replace Mark Lesinski, who has successfully completed his term as President and CEO, and will be continuing his career elsewhere in the nuclear industry.
While Joe is currently focused on CNL’s response to the COVID-19 Pandemic, his mandate will include the delivery of major environmental remediation projects, the operation of Canada’s national nuclear research program, and the $1.2 billion revitalization program to modernize CNL’s Chalk River campus.
Departing president Mark Lesinski believes McBrearty’s leadership qualities make him the ideal candidate to continue CNL’s momentum.
Prior to joining CNL, Joe served as COO and Deputy Director for Field Operations with the Office of Science at the U.S. Department of Energy (DOE).
He brings 35 years of leadership experience to his role.
