I feel like the article you posted has your answer right near the top. It suggests the bill hasn't been written, yet. So the corruption is likely just lawyers and politicians taking their sweet time doing as little work as possible, sitting on committees and expense accounting dinners in fancy Ottawa restaurants.
But I do expect that there will essentially be a monopoly on pot, too.
It's more that "assuming somewhat competent people" (that's probably wrong right there, considering government, not just the Liberal Party) they had this stance PRE-ELECTION. Which means
hopefully they had an idea how they were going to do it, even if not 100% fleshed out, the basics (who can grow, where can be sold from, who can buy (easy, not minors, done), and how to deal with past convictions) should all have been
already decided. I would at least
hope that if a party has it as a major plank of their platform, the basics have been sussed out. Thus drafting, etc, is in the 6-month timeframe (maybe). Thus they should have TABLED the bill this week, and had a nice long (and public) 1st, 2nd, and 3rd readings with lots of committees in-between, making it PASS sometime near this time next year, or (preferably) this fall.
That essentially nothing is done NOW, means they've done nothing so far. Which is gross incompetence, and as others in the media have said, "What about all the people getting criminal records THIS year?" All signs of "who the fuck is
actually controlling the party?" Which is (at least one reason) why I didn't vote for them. Maybe this year we'll find out who with the big purse is really in control of the party, because it certainly isn't Mr. Trudeau Jr. It never has been.
