We had to use a 24/7 service once after a toilet overflowed late on a Saturday. I was skeptical at first, but the plumber showed up quicker than expected and handled it without rushing. The cost was higher than a daytime visit, but not unreasonable considering the timing. I found the contact through
Plumbers in Campbell River, BC and it helped knowing ahead of time who even offers after-hours help. Having that list bookmarked is honestly a lifesaver.
