Contractor Conflict Disclosure - Markham

General Governance and Administration Ontario 3 Minutes Read · published May 24, 2026 Flag of Ontario

In Markham, Ontario, contractors working for or bidding on City projects must disclose conflicts of interest and related relationships early in procurement and contracting processes. This guide explains when and how to make disclosures under Markham procurement rules and related municipal requirements, who enforces the rules, common violations, and the practical steps contractors should take to stay compliant.

When to disclose

Contractors should disclose actual, potential or perceived conflicts as soon as they are known—typically at prequalification, proposal submission, contract award, and whenever circumstances change during contract performance.

Disclose changes promptly to avoid enforcement action or contract termination.

What to include in a disclosure

  • Identification of the contract or procurement (RFP number, project name).
  • Nature of the conflict or relationship (financial interest, family ties, former employment with City, subcontractor relationships).
  • Names of affected parties and dates relevant to the conflict.
  • Steps proposed or taken to avoid, manage or mitigate the conflict.
  • Contact details for follow-up and supporting documentation if available.

Penalties & Enforcement

Enforcement of contractor disclosure obligations in Markham is handled through the City departments responsible for procurement and by-law compliance. Enforcement actions depend on the governing instrument (for example, the Citys purchasing rules, contract terms, or specific procurement documents).

  • Monetary fines: not specified on the cited page.
  • Escalation: ranges for first, repeat or continuing offences are not specified on the cited page.
  • Non-monetary sanctions: contract termination, withholding payments, debarment from future procurement, orders to remedy conflicts, and referral to court or administrators are possible where contract terms allow.
  • Enforcer: Procurement Services and By-law Enforcement or the department that administered the contract typically investigate and enforce compliance.
  • Appeals and review: appeal routes are determined by the procurement documents and City policies; specific time limits for appeals are not specified on the cited page.
  • Defences and discretion: documented reasonable excuse, prior disclosure, approved mitigation plans, or formal variances/waivers where the City permits may be considered.

Common violations that trigger enforcement include failure to disclose prior relationships, undisclosed beneficial ownership, undisclosed subcontractor ties, and misleading statements on bid forms.

  • Failure to disclose known relationships with evaluation committee members or City staff.
  • Undisclosed ownership or control of subcontractors used on the project.
  • Material misstatements on qualification or bid forms.

Applications & Forms

Some procurement processes include a Contractor Conflict of Interest/Declaration form within RFP or bid documents; where a dedicated City form exists it will be published with the solicitation. If no specific form is provided, contractors must include a written disclosure in their submission or notify the issuing City department. Specific form names, numbers, fees or filing deadlines are not specified on the cited page.

Always check the solicitation documents for a required disclosure form and include it with your bid if requested.

How to comply

Practical steps to meet Markham disclosure expectations focus on timely written disclosure, recordkeeping, and proactive mitigation:

  • Review the procurement documents for explicit disclosure requirements before submitting a bid.
  • Prepare a standard disclosure template to attach to proposals and to update during performance.
  • Where a conflict exists, propose mitigation steps (screening, independent auditors, altered reporting) and document approval requests in writing.
  • Report potential conflicts promptly to the contact named in the solicitation or to Procurement Services.

FAQ

Do I need to disclose relationships with subcontractors?
Yes. Relationships and ownership interests in subcontractors that could affect impartiality should be disclosed in the bid or to the contracting officer.
What if I discover a conflict after contract award?
Notify the City promptly in writing and propose mitigation; failure to notify may lead to enforcement or contract action.
Are there standard City forms for disclosure?
Some solicitations include a declaration form; otherwise make a written disclosure as part of your submission.

How-To

  1. Identify any actual, potential or perceived conflict affecting the bidding team or subcontractors.
  2. Complete the disclosure information, including contract identifiers and affected parties.
  3. Attach the disclosure to your bid submission or email it to the procurement contact named in the solicitation.
  4. Propose mitigation measures and request written acceptance from the City if needed.
  5. Keep records of communications and any approvals for audit and defence purposes.

Key Takeaways

  • Disclose early and in writing at each procurement stage.
  • Use solicitation documents to find required forms or contacts.
  • Propose and document mitigation if a conflict cannot be avoided.
