I needed this info, thanks!This thread is a bit old, but I would like to correct it. You DO NOT need Canadian investors if you are going through an incubator path. You only need Canadian investors if you are going to apply to Angel or VC designated organisations.
Most applications for PR were approved historically by a large factor through an incubator track, so those applicants did not get funded through an investor. Both options with funding and no funding have similar outcome - a letter of support from a designated organization.
