Take courses in a Canadian college for a permanent resident

[CND3A]

Hi,
I have a permanent residency in Canada.
I was in Toronto for few weeks for landing procedure, and I'm planning to g back there.
I have a chemical engineering diploma with almost 6 years of experience in Oil & Gas production in my home country.
I'm planning to take courses in a Canadian college for carrier change (HVAC technician)
my questions are:

1 - Is it easy to go back to school in Ontario?
2 - Is it possible to study and work (I'm single man) ?
3 - Is it possible to get my credentials assessed while I'm studding ?
4 - Is it really wise to study for 2 or 3 years to get a Canadian diploma ?

thank u in advance
