Admission ~$42 CAD adults / $28 CAD children (3-12); free for kids under 3. The moving underwater tunnel with sharks and rays overhead is absolutely magical for young children. Strollers are very manageable throughout; nursing lounge near the jellyfish gallery. Book tickets online (saves ~10%) and avoid Friday and Saturday evenings when it can get extremely crowded — weekday mornings are the sweet spot.
