I assume you have just added the '*' first in the line to show which
rows you are talking about.

Simple maths will show your error, lets count your opening parentheses

if (ctype_alnum(str_split($zip,1)) {
1 2 3

and now the number of closing parentheses

if (ctype_alnum(str_split($zip,1)) {
12

So we get 3 opening parenthesis and 2 closing, this is what the "Parse
error: syntax error, unexpected '{'" is about, you need to close all
your parentheses.

You know you will end up with loads of if cases if you keep on doing
this instead of using a regular expression, this would speed it up and
make your code a lot easier to read (case insensitive):

if(preg_match("/^[a-z]\d[a-z] \d[a-z]\d$/i",$postcode)) {
// this could be a valid Canadian postcode
// just add what you need to do to check it against
// Canadian Post, worst case use the "Find a post office"
}
