TORONTO -- It's been a whirlwind of a week for some tenants of an apartment building in Toronto's west end. Residents of 1407-1409 Bloor Street West were left scrambling to find a home after they were told to vacate their units within 24 hours as it was deemed unsafe by city officials. Earlier last week, emergency crews were called twice to the building due to the detection of high levels of carbon monoxide. Subsequently, the city found that the four units located on the second floor of the property managed by Brad J. Lamb Realty were built without a permit. "No one even had boxes. No one knew where they were going to go, how they were going to move all of their personal effects. It was very hard to get in touch with the landlord's property manager. They were avoiding our calls. They had very little information for us," Miles Gertler, one of the residents, told CTV News Toronto Sunday.
