the federal liberals tried an experiment with the ubi in the 70s, but the results were never released. the open secret is that it worked a little too well.
the provincial liberals were experimenting with a ubi before they lost the 2018 election, and they seemed to be on the brink of adopting it. it's one of the first things that doug ford trashed when he took over.
the greens have had a ubi in their platform for years.
the ndp have generally opposed the policy, but have recently jumped on the bandwagon as a reaction to the pandemic.
