Dividend Calendar
This new tool helps you keep track of important dividend dates for TSX companies. It is easy to navigate and provides a range of filters to give customized results.

You can filter your search at any time using three different criteria: Sector, Class and Event. Sector consists of the various industries and groupings that companies and securities are organized by such as mining and financial services. Class represents the types of listed company stock that are differentiated by the level of voting rights shareholders receive. Event allows you to select what type of dividend date to display. For example, you could choose to see the dates dividends are declared, or the date they are actually paid out.
You'll need a free TMXmoney account to access it, but it looks pretty promising.
