This paper explores signage in the linguistic landscape of Toronto that is addressed to Hungarian-speaking Roma asylum applicants, centering on multilingual public-order signs that transfer warnings or prohibitions. Such signs are generated by institutional agents who often employ machine translation (Google Translate), producing ungrammatical texts in apparent Hungarian. Using ethnographic interviews, the paper examines the indexicalities that such multilingual signs have for distinct groups of participants, including Roma addressees and English-speaking ‘overreaders’. While institutions may consider the generation of multilingual signs as indexical of open-mindedness towards migrants, Roma interviewees may view public-order signs as indexing racial stereotypes by presupposing aberrant behavior, and may consider ungrammaticality as indexing an unwillingness to engage in face-to-face interaction.
