Any Drive test examiners here? (G2 question)

My nephew failed his G2 test last week and I'm taking him for his retest in January.

I looked at his results and he was deducted marks because he *Failed to observe properly at uncontrolled intersections*

Uh, wtf does that mean? Been driving for 20 years and been paying close attention the last few days and I haven't seen an uncontrolled intersection yet. Every intersection I see is controlled in at least one direction.

And the MTO example is just weird... https://www.ontario.ca/document/official-mto-drivers-handbook/driving-through-intersections#section-1

Does anyone have an example of an uncontrolled intersection? We're in Ottawa and will be doing the test at Canotek if that helps
