If you think it's 1 person, you need to spend time on the International Students forum. At least 7 out of every 10 people that apply for SP get rejected, but this is mainly because people are not applying correctly. Almost everyone on the forum apply to colleges for diplomas and post graduate certificates after having a Masters degree. They also apply for courses that are completely irrelevant to their academic background and their work experience, because their consultants/agent told them to. These are what lead to the bulk of rejections. Other reasons are not enough funds, not well established enough or applying from a country where applicant has only temporary status and they didn't show how the program will benefit them in their home country.
If you are a Master's degree holder and you apply to a public university for PhD or even another Masters degree with specialization that is relevant to your work experience and future career growth, articulate your study goals properly in your SOP and show enough funds (including source of such funds), then you will likely get your permit approved.
When I joined the students forum and saq how almost everyone was getting rejected I was scared at first but I took my time to read through 100s of pages and tried to understand what the common thread of rejection was. Once I figured that out, I knew the problem was not with IRCC (most of the time) but with the applicant's profile. I was discouraged by members on the forum never to apply with my family because we will surely get rejected, instead I was advised to apply alone first, go to Canada if approved and then call my family 6 months later. Well, that wasn't going to work form me cos we have 4 kids and a husband whose work schedule is quite hectic. So I applied with our 4 kids (did everything entirely by myself, no agents or consultant whatsoever) and we were all approved first time around. The only reason my husband didn't apply together with us was because he was travelling at that time and wouldn't be able to get some of the documents required. As soon as he was back in town, he applied for his SOWP and he was also approved first time around.
All this my long story just to say: if you put in a solid application, you will likely get your SP approved first time around. Avoid all the usual pitfalls and you should be fine.
