Welcome Neighbour ! Algonquin Park area here...
- Please just don't even think of Renogy... tiz all I'll say but look up support & service reviews.
There are several brands available to us in Canada, some with all Canadian components including LFP cells. It all depends on Budget really.
You have the option of DIYing your own or going commercial which of course are pricier.
Being you are in Ontario, here is SolaCity out of Kemptville with several LFP batteries. Be Seated but don't panic LOL.
Shop the best selection of lithium ion batteries (LiFePO4) in Canada and buy online. We ship all over Canada or offer local pickup near Ottawa, Ontario.

Then we have CanBat
LifePO4 battery Canada. Buy online with free shipping in Canada. Available in 12V, 24V, 36V and 48V. For RV, marine, trolling motors, fish finders & more!

Serious Commercial:

NB: Now Rolls Surette (Big Lead Batt Maker) also makes LFP Packs AND a lot more models/versions have been added and price improved a LOT too but "it is Rolls Surette" so not cheap discount stuff eh!
https://rollsbattery.com/catalog/ select LFP on the left upper panel.
IF you are curious about assembling your own, please have a look at this resource I prepared, download the PDF:

PS: I am in process of a major system revamp which will be freeing up an assortment of BMS, Relays, Contactors and much more, I will be posting that up soon, but PM me if there is anything you are looking for, most of it will be heavily discounted new & unused and used materials.
