Yes. In July 2017, Justice Conway of the Ontario Superior Court of Justice confirmed in a written decision that posting a notice to creditors on NoticeConnect satisfied an estate trustee's duty to advertise for creditors under s. 53(1) of the Trustee Act.
Our notices are also government-approved in Saskatchewan. The province has updated section 8 of its estate administration regulations. Lawyers and trustees can advertise on NoticeConnect or in a print paper, they do not need to do both.
