BBF,
Are you telling us that the use of deadly force in self defense or to protect the lives of your family is illegal in Canada? If so I hope you each have your own private Mountie assigned to you 24/7.
Brett. This is not a simple yes or no situation. Of course everybody wants to protect himself and family.
It is a question of justified homicide which the prosecution will try long and hard to prove was not there to start with. Your legal costs will be staggering, guaranteed.
What were your options?
They Govt. will come up with all kinds of "You should have's done this or that... including running away and handing over whatever is demanded.
The next problem for you will be be fact that you had access to your handgun to repel an intruder. Storage regulation of a restricted firearm are stringent and the mere fact that you could readily defend yourself by using that firearm is prove that it was not stored/secured properly.
You have less problem by crushing the intruderes skull with a baseball bat or a meat cleaver.
There are only two(2) legit reasons for a Canadian to own a handgun.
1. Your occupation(very few qualify)
2. Target shooting.
Personal or home defense does NOT qualify
