This tired old queue jumping red herring. Basic rule refugees are not immigrants. 

There are different queues (and selection criteria) for temporary and permanent immigrants and for refugee claimants. Note the name of our legislation... the Immigration AND Refugee Protection Act . 

And there are even different queues for different types of refugee claimants as set out in our international agreements that we have passed into our domestic law in the IRPA. 

Refugees who flee their country may apply overseas - usually from refugee camps where they are pre-selected by the UNHCR and then evaluated by Canadian officers abroad or privately sponsored. Refugee claimants may also appear at a Port of Entry and seek protection but if coming from the USA will be sent back per the Safe Third Country Agreement. Refugee claimants may also make claims to an inland immigration officer whether legally or illegally in Canada per the IRPA and are entitled to have the claim processed. 

Not queue jumping.
