Hi, I live in Saskatchewan. I got a speeding ticket in April 2003 for
$177.00 in British Columbia. I did not pay it because I was out of
province. I heard that after five years it just gets erased. Now, for
the last week I have had a collection agency that keeps calling me
saying that if I dont pay it it will affect my credit rating. Can that
really happen or is he just trying to "scare" me into paying it?

In Australia once a collection agency is involved the least of your
problems is your credit rating (which is affected).
The increase from the original fine (penalties for late/non payment etc.)
And the very distinct possibility of your possessions (to the value of
fine + penalties) being seized!
Non payment of parking fines can result in the suspension of drivers license.

Why don't you just contact the province you got the ticket in and ask
them the status of the ticket.
