Canadian Immigration minister Jason Kenney announced today that the Canadian government will start the temporary worker visa program once more.
Starting in 2013, the Federal Skilled Trades Scheme will offer 3,000 visas to qualified workers (especially workers who have recent, relevant experience in the construction industry). This number will increase over the next few years because many people in the construction industry want to offer jobs to qualified immigrants.
You can read a bit more about the program here. It's worth noting that you do NOT have to meet the typical language requirements (IELTS Level 7 or Cambridge Advanced Certificate) - having a minimum knowledge of English or French is fine.
I'll post more information as I find out about it.
