Milos Raonic will lead Canada against Spain in Davis Cup play in Vancouver next month.
The 15th-ranked Raonic is coming off a fourth-round loss to Roger Federer at the Australian Open.
He, Frank Dancevic, Vasek Pospisil and veteran Daniel Nestor have been the core of the team since 2011.
The World Group first-round tie is scheduled for February 1-3 on an indoor hard-court at Thunderbird Sports Centre.
