Thank you for your question. I will begin and Diane may want to add her own comments.
I was very surprised to see that our rating was slightly better in the past. It was “C”. That is hardly nirvana, but it was slightly better than a “D”. I have to admit that this has always been a source of frustration. It's a difficult thing to achieve. However, I agree with you that, in the case of Montreal, it doesn't make sense.
