The Supreme Court of Canada did not contact Zunera Ishaq.  In fact, the Supreme Court of Canada did not hear her case, or even get to the stage of granting leave to appeal.

And both of the two levels of court (trial and appeal) that did hear her case decided on the basis that the existing Regulation to the Citizenship Act requiring citizenship judges to "allow the greatest possible freedom in the religious solemnization" of the oath carried more legal weight than Minister Jason Kenney's policy banning the niqab. 

It was the Conservative government that took a wholly political view of the situation, not the courts.
