Canada has at least a couple of things in common with Britain. First it has been attacked by Muslims. Second Canada has had and still has, troops in Muslim countries. This is significant since, besides common sense, a sister of the attacker in Manchester has been quoted as saying that her brother was acting for revenge. Revenge for Britain interfering in Muslim countries. 

So our first anti-terror act should be to remove our troops from the Middle East and environs. Canada has no interests there.
