さきさんが引用されている部分は、ワークパーミットがない人のための記述です。
PG workを含むワークパーミットをもって働いていて、雇用者からのPermanent job offerがあるならそれでOKです。
CICのページで言うと、以下の条件のArranged Employmentに該当します。
You are working in Canada on a temporary work permit that was exempted from the requirement of a confirmed job offer from HRSDC on the basis of an international agreement (e.g., NAFTA or GATS), a significant benefit to Canada (e.g., intra-company transfer) or public policy on Canada’s academic or economic competitiveness (e.g., post-graduate work).
Conditions
・Your work permit was valid at the time you applied for a permanent resident visa and at the time the visa, if any, was issued.
・Your employer has offered you a permanent job once the permanent resident visa is issued.
・You are currently working in that job.
