Should i close my Scotiabank account now that i’m home?

So, I went to Canada in 2014 for seven months on a work visa. Came home, been here since.

I retained my Scotiabank account, in the hopes that I’d either spend a lot of time holidaying, doing a lot of business, or eventually moving back. The bank is fully aware of my change of address and are fine with it. Currently it looks like I spend a week yearly in some part of the country (currently planning a Newfoundland trip in June) but the option of doing more (business/moving back) are possibilities in the next 5 years.

On the account is a current ac costing $3.95 a month, and a credit card with $1000 dollar limit. I use CurrencyFair to transfer over a few quid a month to cover the costs.

Should I close the account? Is there a benefit to having access to a foreign currency card, or does the PostFX Credit card from An Post, or using your own (Bank of Ireland) bank card at an ATM abroad, do a better job?
