I'm living in UK for past 10 years.
I've got Canadian PR last year. IT EXPIRES if you do not use it.
A person in Canada temporarily, like a student, is not a permanent resident.
When you are a permanent resident, you can live outside of Canada, but must live in Canada for at least two years(730 days) in a five-year period. If you live outside of Canada for longer, you may lose your permanent resident status
You could come to Canada and look for work if you really have a PR. You are not required to move all your stuff to do that.IF you find a suitable job you can then move in.
You make this sound like you cannot change your mind and move some other place in 5 or 10 years.
You applied for a PR for reason. ONLY YOU know why CANADA has some interest to you other than a pay package.
Are you seriously planing your home on how long it takes you to get somewhere on vacation? You make a few extra hours flying time seem like months.
UK is in the middle? OF WHERE?
I've lived there for 4 yrs. IN 4 years you either found something you liked about Canada or you did not. I doubt you explored much other than around the place your Campus was.
If you travel WEST from CANADA you end up in ASIA also.Eventually to UK. Angle a little to the South and more of the planet is available.
Have you seriously looked at things like land taxes for your home.Utility costs for things like electricity , water and heat.Income tax in the two countries has many different things.
I know UK is in the middle so travelling to different places is easier n cheaper comparatively.
REALLY the bus fare from Canada to USA is $4.50.
How much is a particular view worth to you? A one hour commute? Maybe in few years you will want a car to take the children places. Have you bothered to look at what is involved besides just the purchase price of car. Things like road taxes, Insurance, A driving licence, Road Tolls, Parking, common repairs......
You can apply online for jobs you just need to make arrangements for a short visit for an interview if required in person. In IT you might interview on Skype from your home.
IF YOU GET THE JOB then you can move to a place near the job.
I m looking to buy property in UK . WHAT a city lot. A few acres in some rural estate. Is it next to the best school , the best play area, the best shopping area, the best theatre, the best restaurant, low crime area, near a fire station..... What is each item on the long list worth to you in your purchase of one place over the other.
