IMO, this is simply a renewal of the previous $50M short form prospectus filed in Sep 2016, which had a life span of 25 months and just expired.  Permits the company to raise capital as/when needed for operational or other purposes:

"to be used to for capital expansion, further product development, potential business or intellectual property acquisitions, working capital and general corporate purposes. The Corporation does not have any agreements or commitments for any specific acquisitions at this time."

This is also the exact wording found in the previous prospectus from 2016
