So TMX is now showing that 300,000 shares have been issued yesterday (column on the right). However, the total number of issued shared changed from 186,142,028 to 187,877,315, i.e. by 1,735,287, not by just 300,000. I tend to believe that the total share count is more likely to be correct than the value given in the "description" column.

I changed my spreadsheet accordingly. It now calculates the number of shares issued at a certain date by the difference of the total number of shares. Hope that's correct (or at least has a lesser degree of incorrectness).
