Coming to Calgary from Melbourne, Australia. Finding work?

Hello everyone, hope you are all well.

I was hoping you guys/girls could help me out with a few questions.

I met a girl from Calgary while i was in Europe and really want to come over on a working visa and try and make things work but i don't know how difficult it is to get a job.

I do not have any study qualifications as i have a good paying job back home already.

I guess i have a few questions...

1 - Is it hard to find a good paying job without having gone to university? and is there any jobs people would recommend?

2 - Also how hard is it to find somewhere to rent while i am there? and is it expensive for a one bedroom house or flat?

3 - If things go really well while i am there and my Visa runs out, what happens after that? Do i just get sent home or is there other options.

Really hope someone can help me i would really appreciate it.

Kindest Regards

Edit- Also i have been to Calgary and fell in love with the place while i was there
