Information about montreal city

before you worry about any of those things - do you speak french?  Visiting Montreal on holiday without being able to speak french is workable, but living here it's much harder.

Renting is easy in my experience.  Providing proof of identification, proof of employment and a deposit is usually all they require.  A good website is http://www.padmapper.com/

Getting a job depends on your ability to speak french as far as I know - especially in professional areas such as nursing.  You'll also have to look at your VISA as some restrict working in the health or education field. 

I don't drive so I can't help you with that, but the public transport system is great in my experience.

We just took our passports and documents confirming our residential address to the bank to open accounts.  There was no issue with that. 

Cost of living is reasonable in my experience.  If I shop around I can feed a family of 4 on just over $20 a day with home cooked meals.  Eating out is much cheaper than the other cities I've lived in but we don't tend to do that too often.
