One of the biggest differences between Toronto and Ottawa is the different variety of people leading a variety of lifestyles. Ottawa is very cookie cutter. Everyone knows exactly what they have to achieve by ages 25, 30, 35..... a government job, a car, a townhouse, a marriage, a child, then a single house in the suburbs, another child and a minivan.
In this city, you can be anyone that you want to be and pursue any type of lifestyle. It's too early to decide. I've been here for 2 whole weeks.... And still taking it in day by day and enjoying every moment!
