Serving from 1948 to 1957, he was considered instrumental in the foundation of the social welfare system, and laying the groundwork for universal healthcare. St-Laurent is well known for being a leading proponent in the creation of North Atlantic Treaty Organization [NATO] in 1949, and his work with Lester B. Pearson in the solution of the Suez Crisis is widely considered the foundation of modern peacekeeping.
