Fan frenzy carrying to Britain and somewhere in Canada (8)
I believe the answer is:
manitoba
'somewhere in canada' is the definition.
(Manitoba is a Canadian province)
'fan frenzy carrying to britain' is the wordplay.
'fan frenzy' becomes 'mania' (I've seen this in another clue).
'carrying' is an insertion indicator.
'britain' becomes 'B' (common abbreviation as in GB).
'to'+'b'='tob'
'mania' enclosing 'tob' is 'MANITOBA'.
'and' is the link.
(Other definitions for manitoba that I've seen before include "Canadian province, capital Winnipeg" , "Province of central Canada" , "part of N America" , "Strange boatman I find in Canada" , "State" .)
