Each advertiser program in Pepperjam Affiliate Network has the country of origin's flag in the interface next to the program name. Canadian programs have a Canadian flag listed while U.S. based programs have a U.S. flag.
Also, Canadian programs can be found under 'Find New Advertisers' in the 'Advertisers' tab. Select 'CAD' in the 'Currency' drop down, followed by the 'Search' button. This will display Canadian programs you are not joined to. To find Canadian programs you are joined to, click 'Joined Programs' in the 'Creatives' tab and select 'CAD' in the 'Currencies' drop down.
