@JaimeLaPizza I did a bit of digging, hopefully this can help give you a bit of perspective.
As previously mentioned there is 3 main companies representing 90% of the users in Canada. In 2015, there was 29,765,430 users with Rogers representing 34% (or 10,120,246.2), Bell 29% (8,631,974 users) and Telus 29% (8,631,974 users) (1). In 2019, it was projected the number of users would reach 30.6 million (2), while the % between carriers can fluctuate, we will use these numbers as reference. As for the subsidies, I wasn't able to find exact stats for each company. Based on an educated guess, I would think that the main company holds the majority of the users. Where the equivalent for Public Mobile, probably represent less than 1/3 of the users (2,848,551.42 users). Honestly, I really doubt it's that high, probably closer 1-10% (max 863,197.4 users).
Something else that could help establish numbers of users is the community board. So as of today and the stats from the last 30 days, there was 939 participants, 0.01% of the total number of users in Telus. While I see the benefits of this board, I doubt it's used constantly by all users. If you say it's only used by 0.1% of users then the number of users could be equal to 939000.
Well... That's my educated guess.
