^^ once a year is fine if you use a good sealant like zaino.
In terms of good detailers in mississauga/brampton, I personally do not know of any.
For interior, if you have leather it should be conditioned once per season, but if your free time is limited, then once or twice a year will be fine. For other parts of the interior, all you reallly need a vacuum and damp cloth. 303 is good for carpets and cloth upholestery.
