This report provides an overview of the history of the Act to promote the development and recognition of workforce skills in Quebec and compares it to what is being done in other provinces to encourage worker training. The law has had a substantial positive effect on the likelihood of providing in-company training. Recent data also show that Quebec has caught up with other provinces in terms of work-related training. Training subsidy programs used in other provinces appear to have many administrative and enforcement problems and certainly do not dominate the system used in Quebec in terms of their impact on training. A review of the economic theory on the supply and demand of training in the Quebec context does not allow us to presume that companies would be significantly underinvested in training if there were no law. But empirical studies clearly show the effects of the law on the levels of formal training. Nevertheless, we conclude that it is difficult to comment on the effectiveness of the Quebec law. This conclusion is based both on the lack of information on its impact on the portfolio of training used by companies and the absence of studies on the quality and impact of the training encouraged by the law on the productivity of companies.
