The 22-year old Uruguayan winger has joined on a season-long loan with the view to a permanent deal and was thrilled to be linking up with the current league leaders.
"I am very happy and excited to join Whitecaps FC," Techera said in the club statement.
"I will work hard to support the team and will do everything I can to help our team achieve our goals."
Of the signing of Techera, who has netted 10 goals in 24 appearances this season, Whitecaps head coach Carl Robinson said: "We are thrilled to welcome Cristian to our club.
"He is a quick natural winger, who can play on both sides of the pitch. He has great technical ability and will excite in the natural third."
