The Canadian Association of Petroleum Producers, the Coal Association of Canada, the Council of Forest Industries, the New Car Dealers Association of British Columbia and the Railway Association of Canada. What do these organizations have in common? Well, for starters, each of them is a lobby group. That means they're responsible for promoting the best interest of their members. But there's one other thing they have in common.
Each of them - along with 38 other lobby groups - is a member of the Smart Tax Alliance.
That's the organization that's trying to convince you to vote in favour of the harmonized sales tax because they say it's in your best interest.
Now, I'd never claim to be an an expert on taxes. I'm not an economist. But I do have some expertise in dealing with sources, having been a journalist for the past eight years.
So if a source that gets paid to promote a private interest tells me something is in the public interest, I'd have to question that source's motivations.
And perhaps you should too, in the lead up to the referendum on the harmonized sales tax.
