Many thanks for the responses in this thread! I've been in contact with Air Canada and SAS, and I'll summarize the feedback I've gotten from them (through twitter, email and phone):
Air Canada: We understand the problem but won't touch a booking made by SAS. We won't do anything.
SAS: We will only offer a refund nothing else. Maybe check with Air Canada?
As I understand it I have a ticket purchased by SAS and I am NOT (edit) covered by EU261. I'll fight them anyways on this and let you guys know my progress.
SAS doesn't give me any feedback over email, only telephone from Tallinn. I've now explicitly asked them for a written response to this case over the diamond contact box, let's see what they respond.
