About

Provided by McCarthy Tétrault LLP

Unlocking the potential of small modular reactor (SMR) technology requires the support of specialized legal expertise. Leveraging deep knowledge of Canada’s nuclear regulatory framework and SMR experience, McCarthy Tétrault helps leading developers and sector participants address opportunities and risks as the SMR market evolves.

SMR technology is an emerging and rapidly evolving area, seen as critical to the energy transition. Our team has worked extensively for decades in the conventional nuclear space with various participants, and have advised some of the world’s leading SMR developers. Our expertise spans the entire SMR value chain and includes experience with permitting, implementing strategic and Indigenous partnerships, navigating environmental and end-of-life obligations, and assisting with all types of capital raising. We have represented project proponents, developers and investors in the financing, acquisition, development and refurbishment of nuclear energy projects. 

McCarthy Tétrault has developed unique and well-established relationships with industry participants and stakeholders, including Indigenous groups, private equity firms, lenders and potential SMR players, allowing our team to bring such participants together and facilitate developments in the SMR space .
