Substance Law provides legal services relating to privacy law, data governance, regulatory compliance, and data breach response across Canada. Based in Toronto, we advise businesses on Canadian privacy laws, privacy policies, consent practices, data handling obligations, cyber incidents, and privacy-related regulatory matters — from day-to-day compliance through to responding when something goes wrong.
Organizations that collect, use, disclose, or store personal information must comply with evolving federal and provincial privacy laws, and organizations experiencing unauthorized access, disclosure, loss, or compromise of personal information may face significant legal obligations, including mandatory breach reporting requirements. Privacy and data breach risk has become increasingly important for e-commerce businesses, fintech companies, regulated industries, online platforms, employers, and organizations handling sensitive customer or employee information.
We assist businesses in developing practical privacy compliance frameworks and in responding quickly and effectively when a breach or incident occurs.
Canadian Privacy Law Framework
Privacy obligations in Canada arise under multiple federal and provincial legal frameworks. These may include:
- the Personal Information Protection and Electronic Documents Act
- provincial private-sector privacy legislation
- public-sector privacy laws
- health privacy legislation
- industry-specific regulatory obligations
Privacy oversight may involve regulators such as the Office of the Privacy Commissioner of Canada. Businesses should ensure that their privacy practices comply with applicable legal requirements.
Privacy Compliance Programs
Privacy compliance requires more than simply posting a privacy policy online. We assist businesses with:
- privacy compliance programs
- internal privacy policies and procedures
- data governance frameworks
- consent management practices
- employee privacy policies
- privacy impact assessments
Organizations should implement privacy practices appropriate to the sensitivity and volume of personal information they handle.
Privacy Policies and Website Compliance
Businesses operating websites, applications, and digital platforms should ensure that their privacy disclosures align with Canadian laws. We assist with:
- website privacy policies
- mobile application privacy terms
- cookie and tracking disclosures
- online consent practices
- data collection transparency reviews
Privacy disclosures should accurately reflect how information is collected, used, stored, and disclosed.
Consumer Privacy and E-Commerce Compliance
E-commerce businesses often collect significant amounts of customer information. We advise online businesses regarding:
- customer data collection practices
- online checkout disclosures
- subscription and account information handling
- targeted advertising and analytics
- third-party tracking technologies
Digital businesses should ensure that customer information practices comply with privacy and consumer protection requirements.
Employee and Workplace Privacy Issues
Employers may face privacy obligations regarding employee and workplace information. We assist with:
- workplace privacy policies
- employee monitoring practices
- remote work privacy considerations
- HR data handling issues
- confidentiality and access controls
Workplace privacy obligations may vary depending on jurisdiction and industry.
What Is a Data Breach?
A data breach generally involves unauthorized access to, disclosure of, loss of, or misuse of personal information. Examples may include:
- hacking or cyberattacks
- ransomware incidents
- employee misconduct
- lost or stolen devices
- accidental disclosure of information
- compromised online accounts
- third-party vendor incidents
Data breaches may create legal, regulatory, contractual, and reputational consequences.
Data Breach Reporting Requirements in Canada
Canadian privacy laws may require organizations to report certain breaches. This may include obligations under:
- the Personal Information Protection and Electronic Documents Act
- provincial privacy legislation
- health privacy laws
- sector-specific regulatory requirements
Organizations subject to PIPEDA must report breaches involving a “real risk of significant harm.”
Immediate Steps Following a Data Breach
Organizations responding to a data breach should assess:
- the nature and scope of the incident
- what information was affected
- whether unauthorized access occurred
- whether notification obligations apply
- containment and remediation measures
Early legal guidance may help preserve privilege and support coordinated response efforts.
Breach Assessment, Investigation, and Notification
We assist organizations with:
- breach investigations and risk assessment analysis
- determining notification obligations
- internal incident reviews and third-party forensic coordination
- preparing breach notifications and notifying affected individuals
- reporting to regulators and responding to follow-up inquiries
- breach recordkeeping obligations
Proper investigation, documentation, and timely, accurate notifications are important parts of incident management.
Data Breaches and Class Action Risk
Significant breaches may expose organizations to litigation risk. We assist businesses with:
- litigation risk analysis
- preservation and documentation issues
- strategic response considerations
- communications and reputational management
Breach response decisions may affect future legal exposure.
Vendor and Third-Party Privacy and Breach Risk
Organizations often rely on third-party vendors and service providers that process personal information, and many privacy incidents involve those same vendors. We assist with:
- vendor privacy reviews and data processing agreements
- outsourcing and cloud-service issues
- third-party risk allocation and cross-border data transfer considerations
- outsourced data processing and cloud service provider breaches
- contractual notification obligations and indemnity/liability allocation
- vendor investigation coordination
Third-party arrangements should clearly address privacy responsibilities and compliance obligations — organizations generally remain responsible for personal information handled on their behalf, and third-party incidents may still create obligations for the affected organization.
Privacy Risk Assessments and Audits
We conduct privacy compliance reviews and risk assessments for businesses across multiple industries. This may include:
- privacy policy reviews
- operational privacy assessments
- website and app compliance reviews
- vendor risk analysis
- data retention and governance reviews
Privacy audits may help businesses identify compliance gaps and reduce legal risk before an incident occurs.
Cybersecurity and Operational Risk Management
Organizations should maintain safeguards designed to reduce breach risk. We assist with:
- privacy and cybersecurity policies
- incident response planning
- breach preparedness reviews
- employee privacy training
- operational risk assessments
Preventative measures may help reduce both legal exposure and operational disruption.
Regulatory Investigations and Privacy Complaints
Organizations may face complaints, investigations, or inquiries relating to privacy practices, separate from any breach reporting obligation — including investigations by the Office of the Privacy Commissioner of Canada. We assist with:
- responding to regulator inquiries and communications
- privacy complaint management
- compliance reviews and internal investigations
- corrective action planning and compliance remediation
- risk mitigation strategies
Privacy investigations may create real legal, operational, and reputational challenges for a business, even where the underlying complaint is ultimately resolved without a finding against the organization.
Industries We Assist
We advise businesses operating across multiple sectors, including:
- e-commerce and online platforms
- fintech and payment businesses
- cannabis and regulated industries
- food and consumer packaged goods
- healthcare and wellness businesses
- software and technology companies
Privacy and data breach risk vary depending on industry, business model, and data practices — organizations handling large volumes of personal information often face heightened privacy and cybersecurity risk.
