As far as I know it’s a feast day in Canada.
It’s listed as a feast in the General Roman Calendar and it isn’t mentioned at all in the Canadian Bishops’ supplement to the Liturgy of the Hours that I have that lists additions and differences between Canadian and general celebrations.
(For some Apostles we celebrate Solemnities, like last weeks Solemnity of Sts Peter and Paul. I think Barnabas is the only Apostle with a memorial instead of a feast.)
