 While some challenged the need for eliminating vouching, the Conservatives pointed out that Elections Canada recognizes 39 types of identification.The amendments to the bill proposed by the Conservatives on April 25 modified this provision to allow a voter with identification to sign a written oath of his or her residence and have that co-signed by another voter with fully proven ID.This process, for example, allows an aboriginal with a status Indian card, which does not list address, to use that ID and sign an oath regarding his or her residency.
