Canadian supreme court judges still respect and uphold the privacy card with respect to providing a link between the ISP, IP address and user info. There have been three exceptions but only with respect to anonymity in a criminal case and where physical crime was involved, not copyright or simple gag order requests.
The MPAA and RIA have no hope of getting user info from an ISP anymore, it's against Canadian Constitutional Rights, has been identified as much and remains that way. ONE Supreme Court judge tried to overrule it but it was very quickly appealed and his privacy was respected.
The MPAA actually got screwed a while back too, they were allowed to collect info but the ISP refused and just gave the IP addresses. The ISP would rather be fined for noncompliance with the MPAA than get sued for a breach of privacy through Constitutional Rights.
ISP's have provided IP addresses in bulk to MPAA, almost while laughing, because that data does not allow the MPAA to take action on an individual. They will not offer the contact details of the data owner. As far as cloud based security and privacy, it falls under very similar laws and Google does NOT have any rights to information stored in their cloud networks, it's quite different than a land line based ISP with a hard wired modem.
If you were American you'd be right, there's no privacy laws protecting Americans, as you are Canadian I'm surprised you didn't realize life here was a lot more protected.
