Typically what happened in the past when MPs and providers required a license, is that they'd come in a couple of times a year to do license checks, make sure the folks were there willingly and offer services if they wanted to get out. Not sure what that looks like now with the city getting rid of that. I'll parrot what others have said here many times before. Stick with who you know or is well established.
A couple of years back I was in Regina, and it was common for the LE there to book an appointment, have a conversation to make sure the providers were there willingly. A well known provider ripped them a new one. She told them to book a 15min next time, and not an hour, as she was touring. I believe they took her advice.
