Ok here is the problem. Under our existing laws in Canada, if you are a Canadian citizen, your right to return to Canada is not prohibited by engaging in crimes or terrorism in other countries. The only thing that delays it is if your passport is lost or expired believe it or not because then there is a delay while you have to obtain outside Canada your passport before you return. Most airlines won't let you on an international flight now without a passport. If you use a fake one and make it to Canada and are caught, you are arrested at the port of entry and held in detention until you prove your Canadian citizenship.
If you are a Canadian cittizen criminal fugitive from having been charged with or convicted of a crime in another country with an extradition treaty with Canada we will with the proper extradition documents provided, send you back to the country you engaged in the crime with.
If you engaged in a crime in a foreign country that is not a crime in Canada or leads to a longer term in jail or execution, we won't send you back even where an extradition treaty exists.
By the way and off topic, any non Canadian citizen who engages in a crime in another country and flees to Canada can apply for refugee status if they can show their crime in that country is not a crime in Canada or gets them a longer jail sentence than in Canada or capital punish- ment.
Now this particular individual is a Canadian citizen. We have no domestic law that says we strip citizenship based on the grounds of engaging in a crime or terrorism outside our country.
As well the fool Justin Trudeau has created a legal precedent that if we do not take back terrorists who are Canadian citizens they can sue us and get millions.
Further in the absence of an international agreement nations would draft and volunteer to incorporate in their domestic laws, there is no protocol for excluding terrorists from returning.
Unless that individual is convicted of a crime in a country with no extradition treaty with Canada and they jail him they can deport him back to us where unless we can show he committed a crime in the Criminal Code of Canada, he walks free which he will if he returns.
Even when a Canadian citizen serve their criminal conviction time overseas in a country with no agreement with Canada to send them back to Canada to serve their time which some countries have with us, Trudeau set a legal precedent we must still try get them out or our country gets sued once they do get out and return to Canada.
You ask me, we need an international treaty that places terrorists of all ages in an international prison in a neutral country once tried by an international tribunal regardless of their age, sex, etc., and convicted of terrorism.
We have a problem. This terrorist is going to use the Kadr precedent to demand bei g sent back to us or he will sue when he eventually gets back. I believe he is in Turkey. Turkey created and funds Isis and openly finances Isis.
