...I have acquaintances, attorneys, who moved to Victoria from Boston two years ago.
I think if you check with them or had visited the British Columbia website, you will find immigration remains VERY constricted. There is an excellent "eligibility questionnaire" you can use on their website. As retirees with high income and healthcare benefits, plus family relatives in BC and other Canadian provinces, you would think Spouse and I would be welcome in Canada.
But you would be wrong! Going through the questionnaire, the result flatly states we "are not eligible for any Federal programs at this time."
The Provincial Nominee Program (immigration quota is already filled for 2015 with its max of 5500 immigrants/yr):

You can find the categories of eligible immigrants here:

It should be noted that family sponsorship is prioritized on married spouses or children who already possess Canadian citizenship. So my MIL, despite having 11 siblings and half-siblings living in Vancouver who were willing to sponsor her, DID NOT qualify.
What many foreigners do is apply for a visitor's visa....and just stay. Visitors can use Canada's healthcare services as long as they pay their own bills. A Canadian customs official told MIL that if she extended her stay, the authorities were not interested in 'coming after her' as long as she paid for her own healthcare treatments. She was not, of course, eligible for their senior housing which was why she didn't move there.
