Alberta is certainly landlocked. But the movement calls for western separation. Ostensibly, Alberta would be the first to separate. Saskatchewan would go next and eventually British Columbia which would give access to the Pacific.
It'll be interesting to see how things pan out, not just this year but in the next decade. I'd take anything from CBC with a grain of salt as it is a completely government controlled media/propaganda outlet as bad as Pravda. With that said, I've seen polling in the 40's, but I haven't seen any polling above 50% for separation, which I believe is the threshold.
Quebec has basically blackmailed Ottawa with threats of secession for decades. They are showered with money taken from producing provinces like Alberta, which seem to really piss the Albertans off.
