It seems that some people on this board know a lot more about this timeliness than I do, but that is not surprising. Here is the second reply from IR I received this morning, and it confirms what others suggested (Tant and EBF, if I remember correctly).

It seems to me that the IR service is now infinitely better than it was, given I never received any responses to queries in the past and now I am getting them within the hour.

Cheers,

There is some debate as to what is considered “timely” by the exchange but my understanding is that it is 48 hours after receiving it (trading days), and the full report must be filed on sedar.com within 90 days. However, the company can put it on sedar right away.
