This dates back to April, but I have not seen it reported on IBS.
The Canadian Bar Association has filed a submission on bill C-24 which echoes our concerns with respect to legislation implementing the FATCA IGA. The submission stops short of calling the relevant provisions in C-24 unconstitutional, saying only that it “implicates” s. 15 of the Charter:
Targeting dual nationals for citizenship revocation results in differential treatment based on ethnicity or national origin and therefore implicates section 15 of the Charter. Canadians from countries that do not recognize dual nationality would not be subject to the provisions. However, Canadians whose ancestors came from countries that recognize dual citizenship and pass citizenship to generations born abroad would face the prospect of revocation. Entire ethnic or national communities would either be subject to the provisions or not. Gradating the rights of Canadians on the basis of the laws of another state creates different classes of citizens. It is unfair and discriminatory. (p. 19)
The submission of the Canadian Bar Association is available full-text here:

Bill C-24 is now in final stages of passage in the House of Commons. To become law, it must also be passed by the Senate and signed by the Governor General.

As most of us will recall from our school days, an iceberg is a deeply deceptive thing since 90% of its mass lies hidden beneath the waves. Like an iceberg, the full reality of FATCA remains largely hidden from view, even now, a mere 20 days before its implementation.
