I understand the purpose of the article and it is important to be critical of whatever party is in power because they certainly aren't going to do the right thing for the sake of doing the right thing. I'm not a supporter of the Liberal party but this article doesn't really point out the issue. The issue is the misplacement of blame.
The article talks about how the Federal Liberals aren't doing anything about housing and consumer affordability but those are provincial issues. Yukon, Newfoundland, and British Columbia are the only provinces currently not run by conservatives. The most effective communications the Federal Liberals could do would be to educate the populace on what is within their power to change and what is a provincial responsibility. It likely won't matter much because a large number of voters aren't interested in educating themselves on politics. But the majority don't understand Federal vs Provincial vs Municipal jurisdiction.
Ultimately, I think the only thing the Federal Liberals can do is focus on the messaging. They are achieving important things but they can't change the things that are impacting the average Canadian on a day-to-day basis. Minimum wage is a provincial issue. Rent and housing is a provincial issue. Health care is a provincial issue. Heck, even the climate change stuff the Provincial Conservatives fought tooth-and-nail on and lost but continue to refuse to address it themselves. I'm not sure what the writer of the article is expecting the Federal government to do other than trying to inform the populace of what they can control and where they need the provinces to do their part to solve these crises.
