Here are the Rewards Canada Top 5 Small Business Credit Card Sign Up offers for this month! This is not a 'best' credit card list like our Top Travel Rewards Credit Card rankings but instead a look at cards for small businesses that have very good acquisition (welcome/sign up) offers. As always when choosing a card you should always take other factors into account other than the just sign up bonus, but when some of these cards are first year free, they can and do pay off even when you grab them strictly for the sign up rewards.
