I have from time to time been asked for feedback on refugee matters. For example, I was part of a lobby group a couple of years ago on behalf of the Iraqi community--religious minorities in Iraq--that did a significant amount of lobbying. I wrote a report at that time about the problems they were having, and some recommendations.
As a result of the efforts of that lobby group, the minister did in the end increase the quotas for the visa office in Damascus to allow more Iraqi refugees into Canada, if they were sponsored.
