The purpose of this study is to examine the impact of board size and the CEO (Chief Executive Officer) duality on the value of Canadian manufacturing firms. A sample of 91 Canadian manufacturing firms listed on Toronto Stock Exchange (TSX) for a period of 3 years [from 2008-2010] was selected. The co-relational and non-experimental research design was used to conduct this study. The empirical results show that larger board size (large number of directors) has a negative impact on the value of Canadian manufacturing firms. The findings also show that the CEO duality has a positive impact on the value of Canadian manufacturing firms. | Board Size, CEO duality, and the value of Canadian manufacturing firms
