You realize that if she can't get enough people in Vancouver (one of the major city in Canada) then is it HER job to run after people all around Canada to be able to build a story? Who would take it seriously if she had to say:
"this is a major issue for new immigrants, a significant number of applications are experiencing major delays which have major negative consequences on their life, well I couldn't find any in Vancouver but I swear, look I found some in Toronto, but I swear it is a major issue..."
It is critical to our life, don't get me wrong, but being disrespectful to her because not enough people seem motivated (or maybe not many finding it significant enough to go in front of a camera) in her city would discourage anyone from putting any effort to help YOU.
