In Canadian opposition proceedings, parties to the opposition must provide evidence to support their case. The evidence must be in the form of affidavits from individuals with personal knowledge of the facts sworn to. The affiants can be cross-examined. It is common in Canadian oppositions for opponents to amend their grounds of opposition as new information comes to light from either the applicant’s evidence and/or cross-examining the applicant’s affiants.
