That's an excellent question.
Because Canada was not a founding member of the AIIB, there's been a little bit of uncertainty regarding the possible shareholding. There is a shareholding allocation formula for the AIIB. The government's decision to join the AIIB envisioned Canada purchasing up to a total of $375 million U.S. in shares, depending on availability. That is the maximum possible amount of shares Canada would have been able to purchase based on the AIIB's shareholding allocation formula.
However, because we're a late joiner, at this point there is only $199 million U.S. in shares available to purchase. If other potential members choose to not purchase all of their shares, there could be an opportunity for Canada to purchase additional shares up to that maximum of $375 million U.S. In that case, however, any potential increase or purchase would be brought back to Parliament through the estimates process.
