This is still up on the CIC website;
Alert – Strike Action
The Professional Association of Foreign Service Officers (PAFSO) union is currently taking strike action. PAFSO union members responsible for processing visa applications have been walking out of offices in Canada and overseas without advance notice.
Posted processing times for both temporary and permanent resident visa applications do not take into account work stoppages. Anyone applying for a visa should anticipate delays and submit their application online as far in advance as possible.
Contingency plans are already in place to ensure all offices remain open and are providing at least a minimum level of service. Priority will be placed on urgent humanitarian applications.
CIC continues to closely monitor the situation.
Also I really dont think having or not having an agent will make any difference whatsoever.
