I think that this might be one of the biggest barriers to these services in Canada.
We have very strict regulations regarding privacy and dissemination of personal information.
Basically: any company operating in Canada cannot keep and store personal information without several steps
1. Giving you an "opt in" to collect information. "opt out" isn't enough, you have to consciously say 'yes'
2. The collection of the information must be clearly identified to why it is collected, and how it is to be used.
3. The information collected can only be used for the purposes identified in the above uses and Cannot be used for purposes not expressly agreed upon.
4. The information, once no longer usable by those outlined purposes, must be destroyed / scrubbed of identifiable information and cannot be in the future used or linked to an identifiable individual.
5. At no point can identifiable personal information ever be sold to 3rd parties.
though, there are even more rules, these are the big ones that passed in the PIPEDA act.

However, you are completely incorrect in how Google, Apple and most of the big players use your data. They do not take it, and resell your data. They take it, Use advanced statistics and algorithms for it, and then sell the resulting information. There's no personal information being sold. What they're selling is "from our statistics, X amount of people Enjoy Y products, so, pay us Z amount of money and we'll make sure they those X people see your adds."
if you believe your personal information is being directly sold to other's by google or apple, you've believed way too much of the FUD in here.
