Motion to extend time to be refused on merits only in clearest of cases

Wadden v. BMO Nesbitt Burns, 2014 NSCA 45:

[17]        It is only in those cases where the proposed grounds of appeal are clearly without merit that it would not be in the interests of justice to allow the extension (See for example, McCully v. Rogers Estate, 2013 NSCA 22 (CanLII), 2013 NSCA 22).
