If you just deleted the information, do you mean it was previously submitted to paypal? If so they have it on record, you willingly volunteered that information to them. Once they find cause to pursue a debt you owe, I doubt they're going to use much disgression and say, oh he deleted off this checking account, lots not garnish the bank. Although I can't speak for Canadian laws, the cost of garnishing multipe U.S. banks to pursue a debt isn't more than $10 on the average.
But on the lighter side, I wouldn't worry about it too much, just keep your bills paid and everyone's happy.
Best of luck.
