MTLGFE is outstanding.  I do not know if they still have the girl of the week and the birthday special.  On my birthday last February I had an interactive 3-sum for 300$ because Mike gave me both specials.  Alicia is awesome but she retired.  Recently 4 girls from GoodGirls jumped ship and are at Montreal GFE.  Try Kate, Bella, Brooke and I think there is one more.  I think Chelsea is hot.  there are a few girls to stay away from and their photos are a little shopped but they are good.    

Of course Montreal Sex City is outstanding.    
Wildtimes is very good
Satin Dreams
Goodgirls/Girls4U is my current favorite  
Xxxtase/Delights (same agency) is good.  I had a bad experience last year but it was the girl (see reviews)
Devilish/ GOF were my go to agency for a while but they dropped off a little.  Still not a rip off agency
Avervissante is good too
Nadia's has hot girls too.  
There are a number of great indies as well.  I have reviewed Tianna and Maria Starr recently
