Dude, I was in your situation 9 month ago..... Believe or not, I declined SINP!! I can post my "decline nomination" screen shot if you want to see.
I will explain my situation and reasons here: 1. I have lived in Saskatoon for over 6 years and god its boring and fking cold as hellll. Winter starts at the end of October and end next year May ish.... I have seen snow in June. In Winter the average temp plus wind chill is about -30 ish... dont ask me what its feels like, rule is never stay on out side over 20mins.... if a day temp is -20, you just feels like " god its so nice and warm today!" ... you also have to be good at driving on snow, because after the first snow fall, you wont see the pavement until next spring. More importantly, the spring is the most gross time of the year, because the snow melts, water, dirt and sand mixed .... mud is just splashed everywhere......
2. Job - I left Saskatoon because I couldnt find job after I graduate from University of Saskatchewan with Civil engineering degree. Saskatchewan's economy is greatly depends on potash mine and the potash price has dropped 70% since 2014. It was easy to find a good tech job before 2012 but not now....
3. The choose to stay with OINP because I got a good job here. 2. Much nice weather and lots of fun, malls, KTV, golf everything..... mind me that Saskatoon's biggest mall (which is the largest city in Saskatchewan) is a 2 story building........ believe me or not, most of my friends drove 13 hours back and forth to Edmonton or Calgary buy cloth...
4. My situation is different, since I am inland applicant, If I choose sinp that time, I have to quit my job in ontario, move back to Saskatchewan stay there for 6 month until I get my PR card.... I dont want to give my job since it took about 2000 resumes + 10 interviews to get this job.... so I choose to wait for OINP...
But in your case its different, you just have to accept SINP and waiting until you get your PR.... after that you are free...
