May I short time travel to Canada,how can I get an invatacion?

I would like to see Canada when I have my winter Holiday

what is invatacion? did u mean invitation? first of all you will need to get a visa for up to 6 months from the nearest Canadian Embassy and/or Consulate in your country unless you are from US

To travel to Canada you may have to apply for a Visa (depending on whether or not your country is on the list). After that you must have plane tickets with a return flight and lodging (a place to stay like a hotel etc. and an active bank account or money on hand).
Your best to inquire in your country what is required to visit Canada.
