4. Frequently Asked Questions

What is PIPEDA and how does it apply to my online business?

How long do I need to keep ecommerce records in Ontario?

Your lawyer can tailor a retention policy for data, contracts, and financial records.

What is the difference between a Terms of Service and a Privacy Policy?
