According to the following, The Tory MP's staffers did not know who Marc Lemire was when they replied to his request for Mr. Chisu's support re Bill C-304:
We respond to individuals who write in to our office, regardless of political affiliation or whether they are a constituent or not; that being said we have no way of knowing the political affiliations of whoever writes in or the previous history of anyone who writes in. Mr. Lemire asked for Mr. Chisu’s stance on Bill C-304 so I gave it to him. Corresponding with someone does not mean they share values with that person, and I can guarantee you that if in fact Mr. Lemire is as you’ve described, this would apply.
I have left the personal contact information off this email, as per the senders request. But: someone should have applied teh Googles.
