s.20(e) of the Fisheries Regulations: No person, while angling, shall: attach more than 4 hooks to any line.
You can't use more than 2 lines in any situation, hope this helps! I have my law books right beside me so its word for word the regs I thought were relevant to your question, hope this helps bud, good luck.
