The CRTC has published their regulations under CASL. You can find them at this link.

These look less onerous than the ones published last year. For instance, the “within 2 clicks” part for unsubscriptions is now gone and replaced by “readily performed”. That’s going to be wildly squishy, and so most senders should probably go ahead and default to following CAN-SPAM’s still a bit squishy, but slightly more clear “single web page” requirement.
