Earth's Magnetic Field components in a region

  1. Any know a way I could find out the earths field in the city I live in.

    I ask this because I have performed the charge to mass ratio experiment and my prof said it would be nice to compare the field i found for the earth and the actual field recorded by some institute.

    I can find information for American cities but not for Canadian
