A good site for PC recycling
But quite a long drive from Winnipeg. perhaps? 😀
It's best just take Brett's advice, remove the hard disk to ensure the personal data are protected and see if a local charity shop has a use for it. Failing that, most city or town authorities have facilities to make sure the metals are responsibly recycled.
As to that hard disk - know anyone who owns an angle grinder? Using one of those to cut it stops anyone stealing your bank details.
