This chart lists online sources of legislation, all of which are free to the public through Canadian government sources. Tracing the origin of a bill in parliament or legislature to its final form as a statute, and how it operates through regulation, is useful for legal research. It can help determine the intent of a law, how it has changed over time, and its current status. In the chart below, an asterisk (*) indicates an official source of legislation (current to February 2022). See definitions for more detail on the terminology used in this chart.
