As per Cadian Immigration - Generally, the holder of a Canadian Immigrant Visa may land at any port of entry in Canada without difficulty.
This is not the case, however, in the Province of Quebec, due to its exclusive right to select immigrants. If, in your application for permanent residence, you declared an intended destination in Canada outside Quebec, then landing in Quebec may be problematic. Likewise, you may be asked to land in Quebec if your intended destination in Canada had been indicated as Quebec.
