just make sure you top up the plazma with winter plazma.....and when I say winter plazma I mean the stuff rated for those alberta winters.....and the wind chill......but in all reality.....never heard of anyone removing them but phone future shop and ask them dirrectly.......then let us know! I know all the tv's in cars are LCD and they do not freeze...... but I never thought about plazma.....
