You can check processing times online: http://www.cic.gc.ca/english/information/times/temp/visitors.asp
The Singapore VO reports 14 days for processing as does Manila. So it would seem that if you submit your application now you should have an answer back before November. Just make sure your application clearly demonstrates that you have strong ties (e.g., employment) so that they are convinced you will not overstay your visa.
Good luck!
