Q: Further to Lance's fine suggestion of using CanadaHelps for excess gains I can add TD's Private Giving Foundation as an alternative I've used since 2007. A twist is that contributions are endowed over a period, usually 10 years, with annual disbursements to chosen charities. Undistributed amounts are invested in TD's conservative mutual funds so some growth can be expected and a legacy is established. You get to name it whatever you wish eg: The Jones Family Foundation. Minimum $10,000. Details:
