If a lower court has erred in applying the law, or if the SSc wishes to interpret the law on a particular subject given the circumstances of the case then it is free to grant leave to appeal if it so wishes.
(*in fact it would be correct to argue that the correct application of the law, no matter how minor,
is a matter of 'national importance')
Just as is true in the United States, the vast majority of appeals to the SCC are denied. There is virtually zero chance that the SCC would allow an appeal on an issue that a 3-judge panel of the FCA didn't deem worthy to consider.
