What is a Canadian system?

A Canadian system consists of 26 bets which transpire from 5 picks. Ten 2-pick multis (parlays), ten 3-pick multis (parlays), five 4-pick multis (parlays) and one 5-pick multi (parlay). At least two of the five picks must be correct to gain some winnings - the exact amount of the winnings depends on how many of the predictions prove correct.
