If you did not get it in the package you can download from the cic.gc.ca website.
I just made a travel form myself in MS Excel format in my PC and submitted. It was accepted and I got PR accordingly.
If you wish you can do it, if there is any problem to get the form. You have to specify the dates of travel, (from - to). country visited, purpose of visit. ( ex: tourist/visit, study, job, pilgrimage, treatment etc). Then sign at the bottom as a declaration.
