Submitting an incomplete application. Roughly half of Ontario CUP delays trace back to missing signatures, the wrong form revision, or fees paid to the wrong department. Run through the Ontario clerk's checklist twice before you submit.
Filing without confirming zoning first. Even in mid-sized cities like Ontario, applications get rejected because the proposed location isn't zoned for the use described in the application. Pull a zoning confirmation letter from Ontario's planning desk before the licensing application goes in.
