Yes, there are some good SIP providers in Poland that you can use to set up a Polish local number in Canada. Like VoIPstudio, RingCentral, Netia, Orange Polska. To set up a Polish local number in Canada using SIP, you need to register with a SIP provider in Poland that provides a virtual phone number.
