I'll try to be really efficient.
If there is a duplication of data series between provincial and federal governments, you have the potential for misalignment between those series. Think of 12 provinces generating series and the federal government generating their own. Which one becomes right if they're misaligned? That's the question. It takes a lot of understanding to unpack what the assumptions are. They may all be valid, but what are the assumptions between them?
There are misalignments between regions. I'll give you an example of what I do: crude oil. Alberta publishes crude oil by quality—light, medium, and heavy—and there are cut-off points based on the density of the material. Saskatchewan does the same, but the density cut-off points are different. Unless you know that, if you start comparing these things, you can get some misunderstandings if you need that level of detail, and that depends on who your audience is. For our clients and what we use, we need that level of detail. The general public may not. The federal government has a role to align—
