You just have to go north. I used to work in James Bay (~55° lat) and on almost every clear night, one could see a thin veil on the the northen horizon. There's an aurora "crown" where they are are brightest. It more-or-less follows the tree line in Canada and is at lower latitude in the east than west. They also get dimmer if you got too far north but that souldn't be a problem on a bike.
I've seen them twice in Montreal and reported them here. They were bright and spread across the country. I've seen them once while touring (photo below) and were the only thing missing during last summer's tour (I was in Labrador near the equinoxe).
After that night, I had a chat with the campground owner on how RV goers missed the whole show. He said he wakes people up sometimes.
