No, I don't. There are 12 months in the year and there are very many more heritages and peoples to celebrate, so no, I don't see an issue. As Senator Frum commented, the reason we've selected May is that it will coordinate with the Ontario and the U.S, and also some significant dates.
As an anecdote on the Ukrainian connection to this Jewish heritage month, I had the pleasure of meeting the Ukrainian Prime Minister about a month ago. He was in Ottawa, and I went to a reception and was introduced to him, and the person who introduced me said something in Ukrainian, and all of a sudden he turned to me and said, “Shalom”, and put out his hand and embraced me. I didn't know the Ukrainian Prime Minister was Jewish. I went back and did a little bit of research and learned that he comes from a small town where he'd been active in re-establishing the synagogue. He's been active within the Jewish community in Ukraine.
This was new to me, but it just shows you that there are these stories that exist, and maybe there's some connection to that in your Ukrainian community as well. Who knows?
