I suggest that if you get $57k/yr or more in the GTA as an entry-level offer, you should be pretty happy. Don't hold your breath for $60k- that would be very generous.
Obviously, $3k/yr will be completely forgotten easily, either plus or minus- at your age and experience level, what matters far more is what kind of experience you're getting and how interesting the work is.
If you're only commanding $53k or less, stay put unless the job looks awesome, because you're going to take a big cost of living hit. The likelihood that an awesome job comes with a well below-par salary is fairly poor in my experience- a well below-par salary more often comes with an exploitative management, poor raises going forward etc. Sometimes (rarely), a below-par salary can come with a credible benefit such as profit sharing or share ownership, but at the entry level these things are, on average, a very minor portion of total cash compensation.
