When will Canadian abusive charity gifting tax shelters end?

Canadian abusive charity gifting tax shelter schemes will eventually come to an end. At their height in 2006 the few charities involved with abusive gifting tax schemes issued $1.3 billion in inappropriate receipts. That number in 2009 is down to $300 million. With the Marechaux case in 2011, the Kossow case in 2013 and the Berg decision in 2014 the courts have taken a hard line on these schemes determining that no part of an investment in such a scheme counts as a gift.  By 2013 the amount of receipts issued as part of these scheme was down to "only" $100 million.  As long as there are people who think that you can make money off a charitable donation there will be investors. Unfortunately the investors will not only have to pay the back taxes but also interest and penalties which can be substantial.
