Addition for House Extension

I am looking for an engineer in Canada, as I reside in New Brunswick, to sign off on my final plans that were initially signed off by an engineer but the contractor varied the roof pitch during the build from 2/12 to 1/12. So, I just need the final plans stamped off. I have copies of all of the plans submitted and the final plans which are the same of original with just the change in pitch? Thanks in advance.
