Two problems:
(1) Line terminator for HTTP is \r\n not \n
(2) You have not supplied a Host: header

h.print "GET /index.html HTTP/1.0\r\nHost: www.google.ca\r\n\r\n"

I say again: you must read and understand RFC 2616.

This documents HTTP/1.1, which has gained a lot of features. You could try
reading the earlier RFCs for HTTP/1.0 or HTTP/0.9 for a simplified protocol.
