Clearly, a change that would require a public declaration on the public registry maintained by the Office of the Conflict of Interest and Ethics Commissioner or a change to an existing public declaration would always be considered to be a material change. Beyond this, whether a change to information provided in your confidential report is material will often depend on specific circumstances as well as your official duties and responsibilities.
Then I go on to say you should pay particular attention to this, that, and the other thing, and I make a big list there. Basically, I guess my message is that there are some things that are obviously material changes. Aside from that, it's not always so obvious, so the bottom line of the message is to consult us if you're not sure.
