Yes, interior waterproofing is very effective for managing dampness and minor leaks, especially if you're planning to finish the space. It involves installing perimeter drainage channels along the floor-wall joint, applying vapor barriers to walls, sealing cracks with injections, and often adding a sump pump for water removal. It's done entirely inside, so no exterior disruption, and can be completed in just a few days. Great for Toronto homes where exterior access is tricky.

It's year-round workable too, even in winter. Investing in this upfront makes finishing safer and avoids future headaches like mold or ruined drywall.
