I have been reading about this and discussing it with a coworker who has done it extensively on his lake. The benefits being, 1) lake is much calmer at night, so you’re getting a better wave, 2) the grandparents can put the kids to bed and the adults can surf.
For Canada specifically, it looks like there were federal laws that prohibited this, (as well as not having a spotter in the boat), but both laws were repealed in December 2018. This repeal was done at the federal level and so there may be fines (but not criminal charges) imposed at the provincial level but I don’t know that for sure.

Searching this forum brings back some hits in 2011-2013 but nothing really recent and so I’m wondering if there is a following, and what your experience is like? Do you need a tower light bar facing back towards the surfer? Could you get away with only using lights mounted under the swim platform? Any other do this/don’t do this recommendations?
