A mobile business may be considered without a storefront if its actual model meets applicable requirements. Still check address, storage, and permit needs. E-2 criteria remain relevant treaty nationality, at least fifty percent qualifying ownership, substantial at-risk capital, non-marginality, and genuine investor direction.
Match the evidence to the service model
Write down how a job travels from enquiry to payment, then attach a record to each step: the phone number and booking software, the quote template, the licence permitting the work, the insured vehicle that arrives, and the invoice issued. Nationality follows citizenship, not Canadian residence, so confirm the ownership split by passport. Gaps identified this way are usually fixable before filing rather than fatal.
Where a mobile model is questioned, the record that resolves it is usually the licensing file rather than the premises file. Trades regulate who may perform work, in which jurisdiction and under whose supervision, and a file showing the correct licence in the correct name for each service area answers the practical objection more convincingly than a leased address would. Keep the two questions separate in your own notes: whether the enterprise is real and operating, and whether it has somewhere to park.
The failure to guard against is an address of convenience, taken to look conventional, that no part of the business actually uses. A registered office that never receives the work, stores nothing and appears in no operational record adds a fact you must later explain.
