1. Separate company identity, ownership and group relationships

A parent–subsidiary review brings together several questions: which companies are involved, how their shareholdings connect, how corporate records describe those connections, and which date the review concerns. Separating these questions makes the group structure easier to explain and gives each corporate document a clear purpose in the due diligence file.

Three layers provide a useful framework:

  • Company identity: the legal name, corporation number and jurisdiction distinguish each entity within the group.
  • Recorded ownership: shareholder information connects a particular company with the persons or entities recorded as holding its shares.
  • Group relationships: a sequence of documented ownership links explains how companies connect across several levels of the structure.

Consider a hypothetical example: Northern Holdings is recorded as holding shares in Maple Operations, and Maple Operations is recorded as holding shares in Harbour Services. For a review of Harbour Services, Maple Operations is the immediate recorded corporate shareholder. The connection between Maple Operations and Northern Holdings is a separate link further up the chain. Describing both links gives the reader a more precise picture than a shared group name.

Timing adds another dimension. An ownership review tied to a transaction date can distinguish the structure at that date from later changes. Corporate history helps organise that chronology, while financial reporting can add the accounting presentation of the group. These materials contribute different parts of the explanation.

For corporations governed by the Canada Business Corporations Act, corporate records must include a securities register alongside records such as articles, by-laws and shareholder resolutions. This federal recordkeeping framework supports an entity-by-entity approach: the review connects records relating to each corporation to explain the wider structure.

The Canadian Trade Registry provides Canadian company search and verification and corporate document ordering. Its Company Search Report page offers a relevant selection for the identity component, while its Register of Shareholders page addresses recorded ownership. Ordering these complementary documents through the Canadian Trade Registry supports a focused file for procurement, financing, investment or transaction due diligence, with each document serving a distinct role in explaining the ownership chain.

2. Keep every entity connected to its legal name and jurisdiction

Corporate groups often use shared branding, shortened names and similar company names across their operations. A document-based review gives each entity a consistent identity throughout the due diligence file. Connecting the full legal name to its jurisdiction and recorded identifiers helps reviewers match the company named in a shareholding record with the company shown in an ownership diagram.

For federal corporations, corporate names, corporation numbers and business numbers are used for company identification. Recording these details in separate fields makes comparisons between documents clearer. The Canadian Trade Registry’s article on corporation numbers, business numbers and legal names explains these identifiers and provides context for organizing an entity’s identity details.

A working identity schedule can give each company its own row, with fields for:

  • The full legal name as recorded in the relevant document.
  • The corporation number and business number, recorded separately.
  • The federal, provincial or territorial incorporation jurisdiction.
  • The document title, date and reference within the review file.
  • A consistent entity label used in the ownership diagram and transaction summary.

Jurisdiction gives these details their proper context. Canadian corporate records span federal, provincial and territorial frameworks, so a group’s entities can belong to different incorporation jurisdictions while sharing an address or business activities. The Canadian Trade Registry’s federal and provincial incorporation guide discusses this distinction. The record-maintenance provisions considered in this article concern corporations governed by the Canada Business Corporations Act, including their obligation to maintain corporate records and a securities register.

Using the same identity description throughout the file creates a common vocabulary for reviewers. A parent named in a shareholder record can then be cross-referenced to its own identity entry, while the subsidiary has a separate entry connected to its supporting documents.

For this identification layer, the Canadian Trade Registry offers the Extract from Trade Register and Company Search Report. Ordering these products through the Canadian Trade Registry supports a document-based description of the entities under review and gives the ownership analysis consistent company identities to reference.

3. Use shareholder records to document each ownership link

Shareholder records provide a documentary basis for tracing ownership between companies. For corporations governed by the Canada Business Corporations Act, maintaining corporate records includes preparing and maintaining a securities register. Shareholding information includes shareholder names and addresses and details of shares held. These particulars connect an identified shareholder to shares in a particular corporation, giving the review a concrete starting point for describing each recorded ownership link.

Read each record as a relationship between two identified entities. The company whose shares are recorded is the subject company; a corporate shareholder is the entity holding those shares. Matching that shareholder’s legal identity to its own company documentation keeps the ownership analysis connected to a clearly identified business. A useful ownership entry separates:

  • The legal name of the company whose shares are held.
  • The legal name of the recorded corporate shareholder.
  • The number and class of shares shown in the record.
  • The document supporting that particular ownership link.

For example, in a hypothetical group, Harbour Services’ shareholder record identifies Maple Operations as holding 600 Class A shares. The first entry would describe that holding in Harbour Services. A second entry would describe the shareholders of Maple Operations using its own shareholder documentation. Keeping these entries separate makes the chain easy to follow and shows which document supports each connection.

Where a review expresses a percentage, tie the calculation to an identified share class and total. In the example, 600 shares out of 1,000 issued Class A shares represents 60% of that class. Separate fields for recorded ownership, voting information and the wider group assessment keep the numerical description and subsequent reasoning clear.

The Canadian Trade Registry’s Register of Shareholders product page is the principal selection for documenting these links. Its Share Certificate product page offers a complementary selection focused on a shareholder’s holding. The Canadian Trade Registry guide to shareholder registers and share certificates explains their respective roles. Ordering documents for each ownership link supports a structured review package in which every recorded holding has its corresponding documentation.

4. Connect recorded ownership with corporate structure and the wider chain

A fuller parent–subsidiary review places shareholder information alongside documents describing corporate structure and decision-making. For corporations governed by the Canada Business Corporations Act, records that must be maintained include articles, by-laws and their amendments, a copy of any unanimous shareholder agreement, and minutes and resolutions of shareholders. These categories provide a structured documentary account of ownership and governance.

Articles belong in the constitutional part of that account. Where a shareholder record identifies a particular share class, connect that entry with the corresponding provisions in the constitutional documents. This keeps the description of the holding alongside the discussion of its associated rights. The Canadian Trade Registry’s article on articles of incorporation and share classes provides context for this part of the review.

A group diagram makes the wider chain easier to follow. Give each entity its own position and distinguish three levels:

  • Immediate ownership: the recorded shareholder directly connected to the corporation under review.
  • Intermediate holding companies: entities connecting that immediate shareholder to higher levels in the structure.
  • The highest corporate entity included in the review: the endpoint of the corporate chain being documented.

Label each connecting line with the recorded shareholder’s name, the shareholding described, the relevant date and a document identifier. The diagram then functions as an index: a reviewer can move from a visual connection to its supporting record. Using consistent labels across the diagram and document schedule also makes individual links easier to discuss.

Keep analysis of individuals behind the structure in a separately labelled layer. Corporate ownership describes relationships between entities; individual-control analysis addresses the people relevant to that further inquiry. The Canadian Trade Registry’s article on individuals with significant control develops that distinction.

For orders through the Canadian Trade Registry, the Articles of Association product page addresses the constitutional-document component, while the UBO Declaration product page addresses a beneficial-ownership statement. These document types serve distinct purposes within a group-review package: explaining corporate structure and recording declared beneficial ownership alongside the shareholder records supporting each entity-to-entity link.

5. Give the relationship a clear date and transaction history

A parent–subsidiary review is more useful when it identifies the date or period covered. Procurement teams may focus on the group structure at supplier onboarding; transaction teams may compare ownership immediately before and after an acquisition; finance teams may examine a particular reporting period. A dated account connects the relationship being reviewed to the business decision it supports.

A practical chronology separates three kinds of dates, which can appear in distinct columns in the review:

  • Document date: the date shown on the record being examined.
  • Event date: the date of the acquisition, approval or other event described in that record.
  • Review period: the date or reporting interval to which the ownership assessment relates.

For example, an acquisition chronology can place a recorded approval alongside the transaction event and the ownership position documented in the file. Each entry can identify the relevant entities, the associated record and its role in explaining the change. Separate entries for the positions before and after the event make the sequence easier to follow.

For corporations governed by the Canada Business Corporations Act, shareholder meeting minutes and resolutions form part of the corporate records that must be maintained. In a relationship review, their analytical value lies in the specific decision recorded. Where minutes or a resolution record an approval concerning an ownership event, describe that approval with its date and relevant entities, while presenting the documented ownership position separately.

Historical names also help connect records across time. Recording the name used in each document alongside company identifiers gives older and newer records a consistent place in the chronology. The Canadian Trade Registry’s article on corporate change histories for due diligence develops this historical perspective.

The Canadian Trade Registry’s History of Changes product supports the historical component of a review. Its Resolution and Minutes of Meeting product pages address the decision-making component. These documents can be ordered through the Canadian Trade Registry for a transaction-focused package, with each record assigned a clear place in the dated account.

6. Use financial reporting to add the accounting view of the group

Financial reporting adds an accounting perspective to a parent–subsidiary review: how the relationship appears in the reporting entity’s financial information. An ownership schedule records corporate shareholdings, while a financial-reporting schedule records the reporting period and the entities discussed in the financial statements. Keeping these schedules side by side helps explain both the ownership connection and its financial presentation.

When a report identifies a company as a subsidiary or describes its inclusion in consolidated financial statements, record that wording alongside the relevant entities and period. A useful financial-reporting entry includes:

  • The legal name of the company issuing the financial information.
  • The financial year or reporting period covered.
  • The name of the subsidiary mentioned in the report.
  • The report’s description of the relationship and any stated consolidation treatment.
  • The page or note reference supporting the entry.

Consolidation also has relevance within Canada’s federal anti-money-laundering framework. Certain provisions concerning entity identification address subsidiaries whose financial statements are consolidated with those of specified parent entities. Recording the consolidation description separately gives the compliance reviewer a clearly identified accounting fact to consider alongside company identity and ownership information. This keeps the financial-reporting evidence connected to the particular relationship and period under review.

For example, a hypothetical ownership schedule might show Maple Operations as a shareholder of Harbour Services. A separate accounting schedule could record how Maple Operations describes Harbour Services in its financial reporting for a named year. Using consistent legal names and entity identifiers connects the two schedules while preserving each document’s purpose and date. The reviewer can then explain which record supports the shareholding and which supports the accounting description.

The Canadian Trade Registry’s Annual Financial Report product page offers a relevant selection for this component of the document package, covering company identification, the financial year, a balance sheet and limited notes. Including this product in an order supports a review that combines ownership analysis with financial context. The Canadian Trade Registry’s guide to annual financial reports for financial due diligence provides further context for using financial information alongside corporate records.

7. Select a document package that matches the due diligence question

A useful parent–subsidiary document package is organized around the relationship the recipient needs to understand. An immediate-shareholder review centres on the subject company, its corporate shareholder and the recorded shareholding. A multi-level review repeats that analysis at each ownership level. An acquisition review gives greater prominence to dates and transaction records.

Each document should have a clear role within the package:

  • Identity and ownership: Combine company search documentation with shareholder records to connect identified entities through recorded holdings. The Canadian Trade Registry’s Company Search Report and Register of Shareholders product pages describe these complementary document types.
  • Corporate structure: Add constitutional documents to explain relevant corporate arrangements alongside the ownership records. This gives the discussion of share classes and corporate decision-making a distinct place in the analysis.
  • History and acquisitions: Include a History of Changes alongside relevant resolutions or meeting minutes. Together, these records help organize the account of ownership changes and associated decisions by date.
  • Financial context: Add an Annual Financial Report to place the ownership account alongside financial information for an identified reporting period. Describe any group relationship discussed in the reporting using the report’s own terminology.

The finished analysis can follow a consistent sequence:

  1. Identify each entity by its legal name, jurisdiction and relevant company identifier.
  2. Explain each recorded ownership link, including the shareholding described in the corresponding record.
  3. Connect relevant constitutional provisions or transaction decisions to that link.
  4. Identify the document date, transaction date or reporting period.
  5. Summarize the relationship as a recorded corporate shareholding, an intermediate ownership connection or a subsidiary relationship described in financial reporting.

A document index grouped under identity, ownership, structure, history and financial reporting makes this reasoning easy to follow. A short accompanying narrative can explain a supplier’s position within a group or the ownership levels covered by an investment review.
