Funny enough...I just finished reading their resolution document here!
The key is that they often don't follow through on what they say they are going to do, but it is a place to start.
Note the last line of the resolution:
"BE IT RESOLVED that the Liberal Party of Canada advocate for a federal pilot of a basic income supplement in at least one Canadian town or city, in cooperation with the appropriate provincial and municipal government(s)."
So let's not party yet, but it is a good sign, but more of a pilot.
