The biggest problem is the absolutely awful access for anyone without a car. Kleinburg has become another popular weekend day trip destination (the gallery only a part of it), so traffic has gotten worse as well. But it’s an especially affluent part of Vaughan, so you’ll never get decent transit.
Any transit?
There are bus stops 600m away at the road entrance to McMichael and Islington. However, best I can figure they are only used by a YRT school special.
The Islington bus stops at Arista Gate, 3.8km to the south. Leaving one a 4.4km walk to the gallery.
