The question of productivity has always been an interesting question and has always been asked. Unfortunately, economic analysis or any kind of analysis has not provided an accurate assessment as to what is causing Canada's productivity woes.
A lot of theories have been put forward, whether they be that Canadian companies may not be investing enough in machinery and equipment, for example, or that maybe we're not doing enough research and development in Canada compared to other countries. There are theories with respect to personal income taxes being so high, particularly at the low income levels, such that individuals simply have very little incentive to work because a lot of what they end up making gets clawed back incrementally. So the incentives to work are not there.
The reasons are numerous. There are so many possibilities as to why productivity in Canada has been lagging. We cannot put our finger on it.
