This is about Panoramax and not OSM, but I figured a local OSM community is a more appropriate place to ask than the one general Panoramax community.

I recently got myself a 360 camera and I'm looking into mapping out parts of my city and self hosting them through Panoramax. One of the requirements for federation (and I guess for making this data public at all) is that we follow any local laws surrounding publishing such data. Does anyone know where I can find information on what these local laws might be? Is it sufficient to just blur out faces or is there more to it? I'm in Montreal if that's relevant, though I do travel to different cities from time to time and might contribute from other places.
