A change is not effective if only one guard knows about it. Updates should be recorded, approved and delivered through a process that reaches every person who may work the assignment.
At a glance
- Ontario training recognizes assignment preparation and shift handover as core security procedures.
- Clear communication should identify the main idea, responsible person and effective timing.
- Changes that affect access or emergency response should be treated as operationally important, not buried in informal chat.
Use this as a planning checklist
A checklist is useful only when the answers become part of the actual assignment. Record the approved process, identify who can change it and make sure the people providing coverage can access the current version.
Questions to confirm
- Who approved the change?
- When does it take effect?
- How is receipt or acknowledgment confirmed?
Picture this at your property
A property changes the after-hours contractor entrance. If the update is sent only to the current guard, the next shift may use the old instruction. A controlled update process reduces that gap.
The value of the example is the decision process: identify what is known, what remains uncertain, who has authority, and what information should be preserved for follow-up.
Practical takeaway
Use the questions above before coverage starts or when the current process is being reviewed. If an answer is unclear, make the responsibility explicit in the site instructions rather than leaving it to individual interpretation.
