It's a party that's been 175 years in the making as Toronto celebrated a milestone anniversary on March 6.

The city has changed quite a bit over the past 175 years, but we remain the Canadian hub of culture, entertainment, and finance.

From a bustling centre of just under 200,000 people in the late 1800s, the city has morphed into a metropolis that serves as home to over 2 million people.

Diversity has played a role shaping the city's growth, making Toronto one of the most multicultural places in North America.

To celebrate, the City of Toronto  held a series of parties that took place over the weekend of its birthday.

CP24 will celebrate this birthday all month long with a special four-part series "Toronto Turns 175" hosted by Ann Rohmer or Stephen LeDrew beginning on Thursday March 12, live at 9 p.m. The four-part series will feature the history of some of Toronto's richest landmarks in episodes covering architecture, arts, theatre, hotels, transportation, food and immigration.

Hosts Ann Rohmer or Stephen LeDrew and one of Toronto's most famous historians, Bruce Bell, will commemorate Toronto's birthday with a live discussion about some of the best historic highlights. Other special guests include some of the city's most prominent figures including the Lieutenant Governor of Ontario David Onley.
