'Usual practice' of immigration officer is sufficient evidence of conduct:
20 Ms. Burrows, now a senior officer with the Department of Citizenship and Immigration, has been an immigration officer for 20 years. Ms. Burrows testified that her usual practice when recording applicants' answers is to put a "check-mark" in the appropriate "Yes" or "No" box that corresponded to the question on the application form. Ms. Burrows would then sign her initials "DB" and the date of the interview next to the "check-mark". As an evidentiary issue, testimony concerning one's usual practice is admissible and corroborative of evidence of conduct in a specific case: see, for example, Savoie v. Bouchard,  N.B.J. No. 66; (1983), 49 N.B.R. (2d) 424 at paragraphs 27-37 (N.B.C.A.).
