It came from Canada?!!

Look at the property details and report the letter to the ISP.

If it's Canada it's probably sympatico.ca   so the address would be "abuse@sympatico.ca"

Right click on the email attachment and send as an attachment so that all of the property details are intact.

I'm aghast that something like that originated from my country :(

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
