If you applied for another work permitPonga said:If I recall, the language is passive ("You may be able to continue working"), because it is NOT an absolute! If it were, it would say "You will be able to continue working".
Good luck!
You must stay in Canada and meet the conditions of your original work permit. If you applied for a work permit extension before your work permit expired, you can keep working under the same conditions as your existing permit until CIC decides on your application unless you have applied to extend your stay under another category.
If you applied for a different kind of permit
You cannot do any of the activities allowed by the original work permit. For example, you may have come to Canada as a worker and then applied for a study permit. If so, you must stop working once your work permit expires. After that, you cannot work or study until you get a new permit.
