The license_url doesn't have consistent use within existing sources and the current CONTRIBUTING guide and schema documentation aren't clear on what exactly this field should contain. In #790 (comment) I've proposed what I think we should use, but until it's documented I don't think we can expect too much of the field, and this PR uses it to point to documentation of the licensing permissions which is okay for the time being.

If we want the field to point to the publisher's statement on the data license, https://www.ontario.ca/page/copyright-information is probably the page to point to, then https://osmfoundation.org/wiki/OGL_Canada_and_local_variants would go under permission_url. But we'd want to get this schema change accepted and documented first (#790 (comment))

What about the 2023-2027 layer? Should that be added to as best?

It's documented as "coming soon", I'd be happy to add it now but perhaps it shouldn't be marked as best until it's complete. WDYT?

That's fine, can leave out for now and add later when it's ready I think.
