No, Numero eSIM does not provide an unlimited data eSIM for Canada.
The available Canadian plans list a hard data cap of either 20GB or 10GB for a 30‑day validity period, and there is no Pay‑as‑you‑go option for Canada in the data presented.
Travelers who need data in Canada can choose a fixed data plan instead. For example, the Canada 20GB for 30 Days plan costs $28.13 USD and offers 5G coverage, while the Canada 10GB for 30 Days plan costs $15.19 USD and also provides 5G access. These fixed plans can be more cost‑effective for typical data usage unless the user is an extremely heavy data consumer.
