ETA is electronic travel authorization - citizens of some countries including austria can do this instead of a visa. Costs less than $10 and done online.Ok so, was is ETA exactly? Sorry im really clueless about all that. And would i be even able to really stay for a year and do the sponsor? Would there be a risk of me having to get back to Austria if something goes wrong?

You would be admitted to Canada for six months (typically) and can extend visit later (online). Note, when you arrive in Canada _as a visitor_ your plans should correspond to those of _a visitor._
