This is going to be a mess, the amount of refugee claims will only be increasing in the next few years. New refugees are going to face an 11 year wait for refugee hearings, and the costs associated with providing for refugee claimants is only going to increase as well. Canada is stuck with them since the government can't just arrest and deport them.
This is what happened/is happening in parts of Europe. Keep in mind I am not talking about refugees fleeing warzones, but as Trudeau referred to
”For someone to successfully seek asylum it's not about economic migration,"
It's almost as if you cannot just stand at a podium and make "empty" promises about immigration like you're earning brownie points and feeling good about yourself as waves of people clap at you and call you progressive. Immigration is a very complex, multi-faceted issue that involves a lot of money, time, resources, housing and so on. No country can handle taking in large streams of people non-stop if it's not capable of doing so. You cannot wave a magic wand at immigration.
When it's handled poorly or is ill-thought out you can lead your country down a path of unrest, turmoil, financial strain and give rise to right-wing parties that spend all the time beating you over the head for fumbling your own immigration policies/promises.
Canada is a big country, but even Canada needs a leader with a brain to look at immigration for the complex topic it is and work with all of the Government members/agencies to truly knuckle down on what numbers they can support and how they can do it.
Angela Merkel has even had to take note of her own immigration Governmental choices and try and reframe things ~
https://www.thelocal.de/20170704/merkel-party-vows-to-control-migration-more-strongly-if-re-elected The world has gone mad if genuinely intelligent people believe immigration is just a bad word, or something only the far right are allowed to talk about. Sadly some daft comments are probably going to be aimed at Trudeau now calling him all sorts of names or making accusations about him because he's talking about immigration. Yes, there's right and wrong ways to do it, but the point is every single damn Government has to talk about it and sort their border/immigration stances and policies out. People have to accept that.
