Compare the UK trucking to Canadian

Would any one of you chaps know if there is age limit you need to apply for your PR to have a good chance of being granted it after two years in Alberta, Manitoba and Saskatchewan?
From what I have read on Manitoba’s immigration website, the most points you get when being no more than 45 yo, and then with every passing year you get significantly less points towards your PR application.
I’m wondering what’s situation like in those two other provinces,

Thanks
