Calling it a tribute to his wife and a chance to give back to his alma mater for launching him into a successful career, entrepreneur Sheldon Inwentash yesterday donated $15 million to the faculty of social work at the University of Toronto. It’s being hailed as the largest-ever gift of its kind in North America.


The journey really does begin when you start understanding what you are missing. I’ve tried to learn as much as possible, reading a lot and visiting important exhibitions, but it’s essential to rely on a good consultant. When confronted with a work, people react in different ways, and there is no right or wrong path to collecting. You can also expect your strategy and tastes to evolve over time. I often get recommendations to buy what I like, but I don’t agree: you need to know the general context of art to make good choices.
