Wouldn’t say it is very easy but somewhat easier. The TRV must be obtained before the study permit. If you apply after the study permit is approved there will be concerns that you aren’t actually coming for a temporary visit and can be denied. It also comes down to the type of degree. If you are studying for a masters or PhD you are more likely to have your family approved in my opinion. These tend to be actual students and not only studying to seek immigration. Also really depends on your finances. There is never any guarantee that a student and their spouse will find employment or it may take a long time. The focus will always be on the ability for the student to pay for and complete their studies.
I would suggest applying for the study permit first. Including family tends to slow down the process. If you would not come to Canada if your family is not approved then apply all together. A spouse should apply for a SOWP in that case.
Could you please give me your opinion on this;
I have PhD admission to start in September, my wife is pregnant and expected to deliver a baby in May, i have good bank statement, i have been working as lecturer for the last three years ( i got my master degree in May 2016). now I'm about to apply for study permit, should i apply for my wife with me to open work permit, or should i apply for my wife with me for visit visa, or should i apply alone and after i got approved, then apply for my wife and the newborn?
