If it's the show I'm thinking of, it is the border agent version of 'COPS'. And, most episodes take place indoors, at a postal sorting station, looking for stuff being mailed into Canada, or at either a border crossing or the Vancouver airport, watching people make lame excuses for why they're trying to enter the country with the wrong papers, dodgy articles, or a B.S. story. One time they chased a sex offender. He was on a bus. Oh, yes, excitement.
I imagine the producers are desperate for something a little more exciting, and this raid will be edited to reflect that, even if they have to stick some poor guy's pant-leg in a dog's mouth and shake them both, like they're animating a Dr. Who alien.
What they've got now is a mildly interesting look at the stuff average people try to get away with. Very Canadian.
I suspect that if they boiled down 3 or 4 years of episodes they might get enough action for a more exciting 'COPS'-style show. (I'd say 'American-style', but the Canadian version of 'COPS', called 'Serve and Protect' was exactly like 'COPS', only with places I recognised.
In an article in a Vancouver paper, one of the people from the show said that they had releases from everyone before they started filming, which is ridiculous, if it's a surprise raid, unless the only people that count are the officers.
