Entering Canada illegally is clearly a universal right. Trudea's strategy: stop or we'll say stop again. It's surprising there aren't more illegal crossings:
1) Migrants are being rewarded for breaking the law. 
2) Migrants have a disincentive to enter through legal channels because they would be turned away at the border. 
3) Every migrant who walks across can tell their friends back in the US how easy it was - free within a matter of hours + lots of free stuff. 
4) Illegal migrants have absolutely nothing to lose and everything to gain (including the possibility of Citizenship) - it makes sense to break the law.  
5) The Sun Sea migrants were rewarded with citizenship, and even the smugglers got off free of charge. 
7) Trudeau's latest response will only encourage more illegal crossings as the Liberals are making it clear migrants can walk across freely and the only response from the Canadian government is: please don't but if you do cross, we will take care of you - tough decision!
