I signed an employment contract with my employer (in Canada) that included a non-disclosure agreement (I work in R&D). The agreement essentially stated that the information gained while I was employed would be kept confidential in perpetuity.
The company never got around to patenting or otherwise protecting my work before it went out of business. As far as I'm aware, there was no buyer, no employees went elsewhere, it's just liquidated and gone. Since the contract was between myself and the company - which no longer exists - am I free to disclose the results of my work there?
