Thank you so much for your  response and wishes  leon  I hear you and you have a practical approach 
The main reason that I am moving my family is to find a stable base I have been on the move ever since  my child was born and we change country every few years this will be her 6th move  and I promised her no more moves 2 more max . in next three years 
I am attracted towards the  North York region as I feel it is well connected to Toronto  and has better schools . so my wife  would have a larger geographical coverage for Job Search as she is from the service industry  so presence of Subway will keep her mobile 
while I feel though   Mississauga will limit her mobility but she will be more comfortable as there  are loads of Indian grocery  stores and  cultural activity  will be higher as compared to North York ( I mean Indian festivals . place of worship etc) and is comparatively cheaper   .  we would have to buy a car soon if we choose  Mississauga. 

 so do you think my thought regarding North york is right ?
