Unfortunately, Huawei and HiHonor do not directly list the Official Network Connectivity Technical Specifications, so finding accurate information from third-party sites like GSMArena or FrequencyCheck is not as likely.

That linked to Amazon listing above has the User Manual for the BND-L21 provided, however the item model number is 51092ASL, which corresponds to the BND-L24.

Get a clarification from the seller for which model is being sold first. The BND-L24 variant has some capacity of working on Freedom Mobile, specifications wise.

Also of note, FrequencyCheck is not checking against all of Freedom Mobile's spectrum bands, it's only checking the deployed Bands currently, however Freedom Mobile will begin to activate MBS (Band 13) FDD-LTE (everywhere except Eastern Ontario) soon (it's a staggered rollout) and BRS (Band 41) TDD-LTE in areas of British Columbia and Edmonton, likely next year at the earliest.
