Independant Metros That Benefit From Being Close To a Large metro

[Razor]

Not suburban cities, but self standing independent Metros that are far enough from the larger city's orbit but close enough to benefit from the larger city's services, that they may be too small to have themselves. The smaller city could be independent enough where it's basically self reliant.

The first few that come to mind are:

1) Hamilton ( Buffalo and Toronto)
2) Windsor (Detroit) disclaimer: border may often be a hassle.
3) Ottawa (Montreal) disclaimer: At 2.0 hours away, may be too far.
