I disagree with your analysis.
Immigration is one of the issues that both the major parties are in agreement on. The only difference is conservatives want more economic migrants (FSW) and less family based immigration (existing family sponsorships) otherwise both are in agreement that Canada needs more immigrants. It is just the type of immigrant that is the disagreement.
Secondly, as someone mentioned, the scores are higher because now a lot of highly qualified people are coming to Canada since UK, US, Australia, NZ (All the english speaking developed countries) have tightened their rules for immigration and have made it much harder. If you notice that now almost 50% people coming through express entry are Indians. a lot of them are H1B applicants who are looking towards Canada as an option with all the H1B uncertainty. Hence you are seeing the scores rise up due to all these factors. The pool itself is now much larger. When applying to canada on student permit in april 2018 i considered applying for PR back then. I checked my score (456 at that time) and there were barely 200 people above me in the pool. Now, there are probably 10,000 people in the pool with that score.
I didn't gave any analysis just what I felt. I was trying to put a reason for deliberate FST draws instead of regular bi weekly all program draw. First in May and now in Oct, I hope I am wrong and draw happens this week.
Conservatives disagree on number of Refugees canada is taking in and are against setting target never said they are anti immigration. They slander liberals for making immigration too easy. If you know how read between the lines Conservatives plan on making so called easy immigration tough. Now they have not given a clear plan but I doubt it would be a popular one. Easy immigration is criticism which I think liberals have been trying to get away with, recent attempts to make asylum seeking a little tougher is evidence of that and then purposefully playing with draw dates in 2019 which they did not do in 2018 or before makes it a bit obvious. I remember in one of the ROH threads when August 2019 first draw was delayed a CEC applicant specially said when people like me go to work place and say immigration is getting tougher the Canadian Voters do hear that.
The only party Anti Immigration is PPC. But if Conservatives Comes in power 2021 Liberal plan will be gone whether it is good or bad and invites would definitely be reduced as Conservatives supports LIMA + PNP over those without it. So the average CRS would definitely spike.
I know the scores are increasing they have been on a rise since 413 drop. But High 460s has been artificially induced due to planned Scheduling of Draws.
In May 2019 Scores were at 450 and then a 28 days gap. H1B has nothing to do with that it was Government decision.
FST draw trend this year has been the first since liberals came in power in 2015. It was my attempt to put a theory out there for the possible shift in trend.
I am all pro hope but I also believe that Draws just dont happen cause minister felt like it. The departure from previous years practice has to have a reason.
