These are the issues that send applications back for correction in Ontario most often. Avoid them up front and you'll typically clear the queue in the 1-2 weeks window.

Submitting an incomplete application. Roughly half of Ontario Sales Tax Permit 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.
Applying without a sales-tax permit in hand. California requires a separate sales-tax registration before a Retail Seller's Permit is issued. Get that number first.
Not budgeting for renewal. The first Retail Seller's Permit fee is only part of the cost — renewals (varies by state) cost roughly 60–70% of the initial fee, and missing the renewal window in Ontario typically means re-applying from scratch.
