Hi @bibschan, could you confirm if the committee list matches the one on the Cloud Summit website? CanadianCloud/cloudsummit.github.io#146 (comment)

@vincent6767 the committee list you just got Linkedin profiles for is the right list. We had a different committee for Vancouver but since we're prioritizing toronto now, let's go with that list.
