Is Canada doing enough about terrorism?

I've raised that issue before here and
here.

And recently a Canadian of Pakistani descent was arrested in connection with the arrests of 5 terrorists suspects in Britain. And now we have a Canadian of Pakistani descent convicted of carrying and attempting to carry concealed dangerous weapons in air transportation and of making false statements about his immigration status.

But this caught my eye:

A federal agent testified during a November hearing that the names and phone numbers of the current directors of the civil aviation systems in Pakistan and the United Arab Emirates were found in Karim's address book, 10 years after he worked as a computer programmer for the Pakistan Civil Aviation Authority.

The Canadian arrested in connection with the foiled chemical attack in Britain was also a computer expert.
