Earth's Magnetic Field components in a region

Liquidxlax

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
