Is the decision not to serve a notice of alibi an ineffective assistance of counsel?

R. v. Borde, 2011 ONCA 534 deals with whether the intentional failure (that is the decision not) to serve an alibi notice amounts to ineffective assistance of counsel. The Court writes:

Failure to serve a notice of alibi constituting ineffective assistance of counsel?

[20]         Defence counsel examined both the appellant's mother and brother regarding his claim of alibi and concluded that the jury was unlikely to believe them. Counsel for the appellant accepts that it was reasonable for defence counsel to make this judgment initially and to advise the appellant not to testify. Counsel for the appellant points out that circumstances change, as they did in this case, and because the accused always has the right to decide to testify, defence counsel must serve a notice of alibi in all cases. The only exception this rule that counsel for the appellant would recognize is where defence counsel knows the claim of alibi is fabricated.

[21]         I find the proposition too unequivocal. Certainly, having the case go to the jury with an adverse inference instruction is always undesirable for the defence. Every effort should be made to avoid that happening. However, sometimes the defence must choose between the devil and the deep blue sea, as counsel for the Crown put it. Here, defence counsel considered that the appellant's alibi defence would be disbelieved, and that having the police investigate the claimed alibi would harm the defence by exposing its weakness or possibly establishing it was concocted. The appellant was prepared to accept that advice. In the unlikely event that the appellant changed his mind, going to the jury with a failed or concocted alibi would have been worse for the defence in defence counsel's judgment. This was a competent, professional tactical decision that I would not second guess.
