It’s a bit different. Any OWNER who is eligible to be a member of the committee can represent an elected member of the committee provided the committee agrees. This owner can be an existing member of the committee, or not.
Basically the way this works is that once a quorum has been established (and not before) the committee would be asked to approve the “Acting Member”. Sensibly, you would run this past the secretary and chair before the meeting, to avoid confusion.
Interestingly, if the Acting Member doesn’t agree with your opinion, they can cast one vote for themselves and a different one for you.
(1) A member of a strata committee may, with the consent of the strata committee, appoint an owner or company nominee of a corporation that is an owner who is eligible to be a member to act in his or her place as a member at any meeting of the strata committee.
(2) The owner or company nominee appointed is, while so acting as a member, taken to be a member.
(3) An owner or company nominee of a corporation may be appointed whether or not he or she is already a member of the strata committee.
(4) If a person so appointed is a member of the strata committee, the person may, at any meeting of the strata committee, separately vote in the person’s capacity as such a member and on behalf of the member in whose place the person has been appointed to act.
