RE:Q4 will be before the 30 november or the 2 January ?As an audited year-end FS, longer due-date, typically filed in January, and in recent years, earlier in January. An early NR on Q4 revenues is possible, but not likely, since it can be interpreted as "spin" until confirmed by the complete AFS.
Some source I accessed had the Jan 2 date but many sources cannot be trusted. Some companies I follow have dates announced by TMXMoney that are never actual deadlines stated by the company
