The question contains a category misunderstanding:
Geographically, Ontario is ~1.95× larger than France—so France could fit inside Ontario (with room to spare). But they are not comparable political units.
If you meant "How many times does France fit into Canada?": Canada (9.98M km²) ≈ 18× France.
If you meant "How many European countries fit in Ontario?": UK (242k km²) fits ~4.4×; Germany (357k) ~3×; Spain (505k) ~2.1×.
Clarify the comparison you intend.
