Can you assume a molecule is polar if it's non symmetrical?

I believe that is true because if the dipoles don't cancel then the molecule will be charged. In molecules where all the dipoles can cancel because of symmetry, they are considered nonpolar. An example where the dipoles cancel is CO2 which has a linear molecular shape.

A molecule is polar when the regions of electron density do not cancel (i.e. if they are not symmetrical).

If atoms in a molecule are symmetrical, then the charges are balanced by each other and the molecule is considered nonpolar. If a molecule is asymmetrical, it is polar.
