An engineer who takes responsibility, does not cut corners, and is firm and confident in offering advice to clients – making engineers better engineers, and architects better architects.

Lorne Mitchell’s outstanding career is the result of collaboration with architects and owners in the design and construction of buildings. Lorne is known as a pioneer in the development of new heating and cooling systems, which are critical cost elements in both the construction and operation of facilities.

In 1953, Lorne began his career at CIMCO – a company for design build services for both low temperature refrigeration and air conditioning projects across Canada. In 1959, he left CIMCO to join one of his colleagues at R.T. Tamblyn and Associates, now The Mitchell Partnership Inc. (TMP) where he was elected President in 1973.

TMP grew steadily under Lorne’s exemplary leadership and his commitment to building loyal staff dedicated to excellence, innovation and quality. Today, the consulting partners have a record of global accomplishment and professional distinction.
