I went to Iceland about 6 years ago and the person I was with was intent on seeing the lights. Unfortunately, the weather across 10 entire days was unsuitable to see them, so most tours were cancelled. Some small private tours would accept people, but said it was highly unlikely that the lights would show through the clouds. I didn't really know what I was missing, but these shots show it. The cool thing at the end of the trip as a consolation prize was the IcelandicAir plane's isle lights turning into Northern Lights when the main lights were off. That was the closest we got. I hear that you can see them in Canada too.
