What Municipalities Actually Check in a Bid: The Compliance Review Before Anyone Reads Your Price

Most contractors assume a municipal bid gets rejected, if it gets rejected at all, because the price was too high or the references were weak. In practice, a large share of rejected bids never make it to a price comparison at all. They get screened out first, in a compliance pass that checks the paperwork against the tender’s own mandatory list, before anyone on the evaluation side looks at what you charge.

This guide is about that first pass: what a municipality is actually checking, in what order, and which specific gaps are fatal versus which ones a reviewer can let slide. It draws directly on the City of Toronto’s own procurement code, Chapter 195 of the Toronto Municipal Code, last consolidated 2025-07-24 and checked directly against the city’s published PDF on 2026-08-28. Other Ontario municipalities word their own procurement by-laws differently, but the underlying distinction, between a defect that can be waived and one that cannot, is close to universal in Canadian public tendering, and worth understanding before you ever open a bid document.

The compliance pass happens before anyone looks at your price

Toronto’s procurement code gives its Chief Procurement Officer an explicit, named responsibility, separate from evaluating the actual bid: “Assessing compliance with mandatory requirements by determining whether irregularities are major or minor and rejecting bids with major irregularities.” That is a distinct step, done before the substantive evaluation of price and technical merit, and it exists specifically so that non-compliant bids never reach the stage where price gets compared at all.

This matters because it means a genuinely competitive price does not save a non-compliant bid. The compliance officer is not weighing your missing insurance certificate against your low number. They are checking your submission against a fixed list, and if a required item is missing or wrong, your bid can be out before a scoring sheet is ever opened. The same code gives the city a published list of ineligible and suspended suppliers that gets checked at the same stage, and a supplier on that list is rejected regardless of anything else in the submission.

Major irregularity versus minor irregularity: the actual legal test

Toronto’s code defines both terms precisely, and the distinction is the single most useful thing a first-time or repeat bidder can understand before submitting anything.

A minor irregularity, under the code, is a deviation that:

• Affects the form, not the substance, of the bid, in terms of price, quality, quantity, or delivery, and
• Is not material to the award, and
• Could not give the supplier who submitted it an unfair advantage over competitors.

The code allows a minor irregularity to be clarified or rectified, meaning the reviewer can ask you to fix it or can waive it outright, at the city’s discretion.

A major irregularity, by contrast, is a deviation that:

• Affects the substance, not just the form, of the bid on price, quality, quantity, or delivery, and is material to the award, or
• Could give the submitting supplier an unfair advantage over competitors, and
• Explicitly includes, by the code’s own wording, “a late bid, unclear or materially unbalanced pricing information, inadequate amount or terms of bid security, and any other matter identified as materially warranting rejection in the solicitation issued by the City.”

A bid found to have a major irregularity is rejected. The code does not give the compliance officer discretion to waive one. This is the practical answer to “will they let it slide”: if the missing or wrong item touches price, quantity, delivery, bid security, or timing, the answer is almost always no, because the code itself defines those categories as major by default.

The specific documents that fall into the “major” bucket in practice

Three pieces of paperwork account for most avoidable disqualifications, and all three sit squarely inside what Toronto’s code treats as material, not a form defect.

A late bid. The code names this explicitly as an example of a major irregularity. Electronic bid portals close on the exact second the deadline hits, and a bid that lands after that instant is not accepted, no matter the reason. There is no discretion here for the compliance officer to exercise. Submit early, not at the deadline, on every tender, every time.

Inadequate bid security. Where a tender calls for a bid bond or other security, the code names “inadequate amount or terms of bid security” as a specific example of a major irregularity. A bond issued for the wrong amount, from a surety the municipality does not recognize, or missing entirely where the tender requires one, is treated the same as a late bid.

A missing or expired WSIB clearance certificate. Almost every Ontario municipal tender for field or trade work asks for one. A WSIB clearance certificate is issued by the Workplace Safety and Insurance Board showing that a business is registered and current on its premium payments and reporting. It can be requested instantly online through WSIB’s own Quick Access Clearances tool if the account is in good standing, or by email in three to five business days otherwise, and once issued it is valid for up to 90 days, verified against WSIB Ontario’s own clearances page, checked 2026-08-28. Two failure modes recur here: bidding without a certificate at all, and reusing an old certificate that has quietly aged past its 90-day window since the last bid it was attached to. A reviewer checking a stale certificate against today’s date has no reason to treat it as compliant, whatever your actual WSIB standing is.

Health and safety documentation, and where COR fits

For construction and maintenance work above a certain dollar threshold, some Ontario municipalities require bidders to hold a Certificate of Recognition, known as COR. COR is a national health and safety management system standard, and in Ontario, the Infrastructure Health and Safety Association, IHSA, is the sole body authorized to grant it. Certification requires a minimum score of 65% in each individually audited element and 80% overall, verified against IHSA’s own COR page, checked 2026-08-28.

The City of Brampton’s own bid portal is a useful concrete example of how these thresholds get introduced and then tightened over time: Brampton phased in a COR requirement for construction and maintenance projects starting with contracts over $25 million in January 2019, then over $10 million in January 2020, then over $5 million from January 2021, and as of the version of its portal checked 2026-08-28, the stated current threshold remains $5 million for construction projects. Toronto and other Ontario municipalities set their own thresholds independently, and a tender document is the only reliable place to confirm whether a specific contract requires COR; do not assume Brampton’s figure applies elsewhere.

Below whatever COR threshold applies, most tenders still ask for some form of health and safety documentation short of full COR certification: a written health and safety policy, a record of your Joint Health and Safety Committee if you are required to have one under the Occupational Health and Safety Act, or a summary of your safety training program. These are usually treated as standard supporting documents rather than pass-or-fail gates on their own, but a tender that lists them as mandatory will treat their absence the same as any other missing mandatory document: a candidate for major-irregularity rejection, not a minor one.

References, insurance, and the parts that get checked but rarely fail a bid outright

A certificate of insurance naming the municipality as an additional insured, where the tender specifies it, is standard across Ontario municipal tenders. The required coverage limit is set in each tender’s own instructions to bidders, not by a fixed province-wide rule, so treat any number you have heard quoted informally as a starting point to verify, not a figure to submit on. An insurance certificate naming the wrong entity, or omitting a required additional-insured endorsement, is a common and avoidable cause of rejection, and it sits closer to the major side of the line because it goes to whether the coverage actually protects the municipality, which is substance, not form.

Reference checks work differently from the document checklist. Most tenders ask for a list of comparable past projects, sometimes with a named contact at each one, and the evaluator uses those references during the substantive evaluation stage, not the compliance pass, to judge whether your firm’s experience matches the scope of work. A weak or unverifiable reference can cost you points in scoring. It rarely disqualifies a bid outright the way a missing WSIB certificate does, unless the tender explicitly makes minimum reference criteria a mandatory pass/fail gate, which some larger infrastructure tenders do. Read the evaluation criteria section of the specific tender to see which model applies before you assume references are just a formality.

The pattern underneath all of it

Every example above traces back to the same distinction Toronto’s own code draws explicitly: form versus substance, and material versus not material to the award. Late timing, bid security, and financial standing documents like a WSIB clearance certificate go to substance and are treated as major by default. A typo in a contact field or a formatting slip in an appendix is closer to form, and a reviewer has real discretion to let it go.

The businesses that stop losing winnable bids to paperwork are not the ones that get lucky on minor defects. They are the ones that never generate a major one, because the documents that Ontario’s own procurement codes name explicitly, a current WSIB clearance, an insurance certificate naming the right entity, the correct bid security, and any safety certification the specific tender requires, are already in hand and current before the tender is even posted. The next guide in this series covers how to build and keep that standing set of documents ready year-round, instead of assembling it from scratch under a two-week deadline every time.
