Public, Lucky, and Chatr are the third-tier Canadian phone providers.
Similar plans and prices, mostly. They each have their own gimmick and they each sometimes run a special/promo which blows the others away. Public's Reward system is hard to beat, though, especially if you intend to stay across the long term instead of hopping carriers every time you see a better offer elsewhere. Lucky can be a better deal than Public if you do lots of long distance calling to a country in one of their packages (especially if your country is not on Public's "International" list).
Lucky and Public use the same combined "Bellus" network, Chatr runs on the Rogers network, they have different coverage and QoS in some areas (sometimes better, sometimes worse, typically more or less identical). The Rogers network has both the very fastest and the very slowest data speeds across Canada, you could get awesome 5G in a few cities and slow 3G or marginal 4G almost everywhere else, Telus and Bell networks are more consistent performers. Chatr's "endless data" is notoriously slow.
Freedom can be a better deal than Public if you (and the people you call) are in Freedom Zones. Not so great a deal outside the Zones (ie: all the rest of Canada). They focus a lot on "cheap" heavy data plans with big data buckets, but their offerings on low-cost "basic" plans usually aren't so compelling.
I summarized things in this comparison about a year ago. (Some details and prices have changed since then, but I won't bother constantly keeping my old post updated.)
I'm still with Public because they're still the best deal. For my needs, anyhow.
