The objective of this study is to explore the experiences of university students in relation with respect to linguistic insecurity and linguistic discrimination (glottophobia) in Ontario. To the best of our knowledge, no Canadian study has jointly studied these two issues. More than 131 students from Ottawa took part in an online survey. Over the past three years, more than 43% of the participants have experienced or witnessed linguistic discrimination. Regarding linguistic insecurity, over 30% had engaged in self-censorship as a result of linguistic discrimination. In conclusion, the accents and varieties of language and linguistic norms within the Francophone space should not lead to linguistic discrimination or cause linguistic insecurity. Vigilance is required to ensure the sustainability of the French language in Ontario.
