Medical cannabis exists since 2001, then there were attempts to decriminalize (not legalize) recreational cannabis in 2003 and 2004, but both times died off because it could not pass in time before the end of the legislative session.

However, it was followed by a 12 year Conservative government, sometimes a minority government, so nothing happened federally, but there were many provincial court cases that helped change how the laws were being applied.
