I am not in favour of this process because IMHO this is a matter for the provinces to address but it is not just happening in the USA.

Perhaps you missed the  mass shooting that occurred on the evening of January 29, 2017, at the Islamic Cultural Centre of Quebec City, a mosque in the Sainte-Foy neighbourhood of Quebec City, Canada. Six people were killed and nineteen others injured when a lone gunman (alleged to be Alexandre Bissonnette who had expressed far-right, white nationalist, and anti-Muslim views) opened fire shortly after the end of evening prayers.
