If it was the result of a blown approach then with an ILS chances are significantly reduced (near zero). Wx or equipment failure etc not so much.
As far as equipment goes YHZ has 2 ILS approaches and RWY 5 also has an RNAV approach with LPV mins (1 mile vis and 257 above). It's also up to the airline to keep up with the times.
