I am a French Canadian from Montreal. (That's why my English is bad!
) But I spend a lot of time each year in London (UK).
I understand why SAAFE ladies advise against escort agencies, but the situation is different in Canada. And many agencies in Toronto, Montreal or Vancouver are very good.
Personally I would say that there are advantages and disadvantages to being with an agency and to be independent. (And I have done both for several years in Montreal)
A reputable agency run by women is always a good choice: they are more sensitive to security issues and more supportive. You do not have to deal with your advertising, bookings, etc. And you're going to have a lot of work. You will receive half of what the customer will give plus tips.
The only thing you have to do is tell when you are available. For example, "I will be available this week Thursday and Friday evenings from 5.00 pm to 11.pm". A good agency will only accept outcalls contracts in 4 and 5 star hotels. And incalls in agency apartments or in 4 and 5 stars hotels. Punters do not want to have problems with hotel management or with the police. (It's illegal to buy sex, but it's not illegal to sell it).
And yes you will be more anonymous if you work for an agency. On the other hand you will not choose your customers.
If you are independent you must have your own website and I suggest you do your advertising in the Toronto forum called TERB. You will need to be careful to protect your anonymity and have your face blurred on your photos. You will choose your customers (screening) and receive all the sums paid by the customers. You will be in full control of all your business. But in the beginning, if you do not have reviews, you will find it difficult to have customers.
My suggestion? Start with a good agency and then when you are more experienced, you can try as independent. You can then choose what you like best.
Good luck!
