I'm sure there are folks with varying ideas about how to grow savings and investments, but as far as the question of savings accounts we've enjoyed Maxa Financial's (division of Westoba) 1.70% savings account. Have some money in an RBC "high interest" eSavings account, but with the rate down to 0.55% it just isn't worth it like it used to be. If you prefer the big banks, it looks like Scotia can offer you a little better at 0.8% as long as you have at least $5000 parked.
Definitely look into your TFSA and RSP options if you haven't already. Many accounts can be setup as either, giving you different options to save in a more tax-favourable way Depending on if one or the other (or both) work for you in your personal situation.
