If you’re going over as a truck driver then points assessment is only for your Provincial Nominee application, not PR. You will of course be working in order to apply for that, after 6 months, and your ongoing job offer will give you so many points towards it that not an awful lot else matters like age, language abilities, education etc in the PNP you are largely competing against people outside the country who are applying based on having a relative there and no actual job, just looking for the chance to come over and find a job, they will have far less points than you.
AS you are working so PNP is relatively fast at about 6 months or so after application but PR will take you between 1-2yrs, this is for MB. I believe SK is virtually identical, AB is just a pain due to requiring employer application but also the impossibility of finding a job able to employ you in the first place.
