Late Sunday night, the commissionaire opened a cell door and was assaulted by a man being held on the other side.
The suspect then used a cell door key to free another man in an adjoining cell.
Both men then fled the building with officers hot on their heels.
The man accused of assaulting the commissionaire didn’t make it far and was apprehended within a few minutes at a nearby shopping centre.
The second detainee was on the lam for about an hour, but was caught just a few blocks from the division after police cordoned off the neighbourhood.
Blair Letendre, 30, and Clayton Carter, 22, are both charged with escaping lawful custody.
Letendre is also facing charges of assaulting a peace officer causing bodily harm, choking to overcome resistance, prison breach and permitting an escape.
Supt. Brad MacDonald says an operational review of the incident is underway "to determine where improvements in detainee management can be made."
