I failed my G2, does this seem like a good reason?

I failed my G2 at Downsview testing centre on Friday in Toronto. My examiner failed the guy before me. I'm usually a good driver. He asked me to do parallel parking, uphill parking, 3-point turn, and forward parking, but I failed because I didn't fully stop at a red light when making a right turn, going over the speed limit, and not going on my right of way
