Congratulations
Principal applicants and all others must enter canada before the due date on immigrant visa issued, check COPR/ Visa stamped on passport. PA can enter before but others can not enter before PA.
Examined before, When is your medical expiring ? Infact Landing due date is actually expiry of medical results that was submitted along with PR application online. It is 1 year from the date you went to medical tests. if they have expired you will be required to retake them for all. Better to enter before medical expires.
There are many threads about finding work on this forum, Firstly please research difference between CV & resume, also research on cover letters. Canadian employers use SW to filter resume so a standard one will not work, you will be required to alter resume and design cover letter with every job you apply. This will increase your chances of getting a job asap. Visit the section on CIC on preparations for arrival and join as many forums they advice you & you feel useful, they will prepare you for arrival and also for House hunt, job hunt etc etc.
