General rules:
Exceptions may be made at the discretion of the mods.
You can drive 23 hours across Ontario and still be in Ontario. And that's not even considering the northern parts.
23 hours is about as high as you are going to get while maintaining a (relatively) straight path. The north is not really accessible by road.
Edit: I take that back. I managed to get up to 27 hours driving from the Ambassador Bridge to Windigo Lake.
