I'm sorry, I haven't had the chance to speak directly to Mr. Dubé about this, but I was going to suggest a possible subamendment that might help, which is that instead the amendment would read, “...directed at a Canadian or at any person in Canada and must not infringe the Canadian Charter of Rights and Freedoms.”
So, I'd be removing the words “a right or freedom guaranteed by”, but it would still read, “...directed at a Canadian or at any person in Canada and must not infringe the Canadian Charter of Rights and Freedoms.”
