A Canadian consists of 26 possible bet combinations involving selections in 5 different events.
The bet includes 10 doubles, 10 trebles, 5 four-folds plus an accumulator.

A double is a combination of 2 events, treble is a combination of 3 events, a four-fold is a combination of 4 events and an accumulator in this instance means a combination of all 5 events.

E.g You place a canadian bet on games A,B, C, D and E.
Let's say your stake is N50, please note that your total stake will be 50 X 26 = 1300
This is so because your stake is charged separately for each possible combination and winnings are credited for each correct combination as well.

Your combinations would be arranged thus:
10 doubles
A*B X 50 = Winnings
A*C X 50 = Winnings
A*D X 50 = Winnings
A*E X 50 = Winnings
B*C X 50 = Winnings
B*D X 50 = Winnings
B*E X 50 = Winnings
C*D X 50 = Winnings

D*E X 50 = Winnings

10 Trebles
