CASL does seem to be having a greater impact on Canadian spam aimed at other countries.

As part of its 2015 Q1 Security Threat Report, the network security firm Cloudmark has released an empirical analysis of email traffic in Canada, following the coming-into-force of Canada's anti-spam law (informally known as "CASL"). The results show that CASL has had a measurable effect on email in Canada, but the effect may not be what the government intended.

Average monthly email volumes received by Cloudmark customers in Canada declined by 29%, but the percentage of received email that Cloudmark assessed as "spam" actually increased, albeit by an insignificant amount (from 16.5% to 16.6%). In other words, the proportionate impact of the legislation for Canadian recipients has been as high or higher on "legitimate" traffic as it has been on true "spam".
