A more thorough explanation:

Commercial email laws in Canada and the US are part of a larger legal context that includes privacy, telecommunications, and computer-related laws. These laws are struggling to keep up with the rapid development of digital technologies and the borderless nature of electronic commerce.

Canada's Anti-Spam Law of 2010 and the US CAN-SPAM Act of 2003 are examples of laws that attempt to regulate commercial email activity. These laws aim to prevent spam and protect consumers from unwanted emails. However, they are just one part of a larger legal framework that is still developing.

Other countries are also developing their own laws and policies to regulate electronic commerce. For example, the European Union has the General Data Protection Regulation (GDPR), which regulates the collection and use of personal data. China has the Cybersecurity Law, which regulates the security of networks and information systems.

Enforcing these laws can be challenging, especially when dealing with international commerce. For example, a company based in Canada may send emails to customers in the US, which means they must comply with both Canadian and US laws. This can create confusion and make it difficult to enforce the laws.

Overall, the legal context for commercial email and electronic commerce is still developing, and lawmakers and practitioners are working to create a comprehensive framework that can keep up with the rapid pace of technological change.
