One of the first things I learned in law school was the canons of construction: “may” is discretionary; “shall” is mandatory. There are very few circumstances where “may” becomes “shall” in statutory interpretation.
If it said that the Government of Canada would backstop it, would it allay my fears? Yes. The fact that someone has the discretion to do it does not allay my fears, and I'm obliged to you for pointing that out.
