If we look at the current situation as a whole, the biggest barriers for people arriving in official language minority communities have to do with the recognition of their prior learning. When we select candidates for immigration, whether under provincial or federal Express Entry programs, we recruit candidates who are highly qualified and who arrive here with many skills and years of experience. Based on their track record, these people are the cream of the crop, but they can't work in their field of expertise. The non-recognition of their prior learning poses a big problem, because it forces these people to rethink their integration goals and settle for jobs that aren't necessarily in their field to build up the necessary experience, which can take a long time.
I also mentioned language not long ago. Language programs need to be very well structured. I'm thinking of learning English, for example. We know how important this is for francophones in minority communities. But programs have been eliminated and waiting lists are long. These people don't have immediate access to these programs to prepare them...
