It's amusing to me that anyone would think a random smattering of ADUs would do anything at all to push the needle when it comes to housing. This is like fixing linter warnings (but not even doing that!) instead of building an entirely new section of an app. We need the latter.
Fixing housing isn't one thing, it's many dozens. ADU's are just one of many. If your list isn't at least 50 items long it's going to be ineffectual. Here's one example of a reasonable list, it's 55 items long: https://www.ontario.ca/page/housing-affordability-task-force...
And there are still many other things I would add.
