If I might also quote from Broadview's submission. Leslie Dema, the president, says:
The rise of copying as a substitute for the purchase of original works has caused a steep decline in Canadian sales revenue at Broadview Press. 55% of our revenue came from Canadian sales in 2013; this has dropped steadily, with only 41% of our revenue coming from Canadian sales in 2017.
If you read the brief, you will see that they have shifted their focus to the American market despite being very committed to Canadian authors and Canadian students, but there's not a market here for them to sell into anymore.
