Many styles have similarities to Nishio senseis style of Aikido, but it would probably be very difficult to find a style that completely mathces what you are doing now. Especially the ken-tai-ken, ken-tai-jo and to-ho iai will be difficult to find somewhere else. It is very unique for Nishio sensei. Other senseis have weaponswork but it's not the same.
From a friend of mine I have heard that Nishio sensei is not really big in Canada, so you should concider changing to a different style or travel to a different country. Denmark is not that different from Canada I've been told - and our national 'style' of aikido is Nishio style
