North Americans tend to have very similar weddings with the same traditions. There's not much difference between a Toronto wedding and a California wedding. In fact, most differences in Toronto weddings and American weddings are based on religious factors. However, there are a few Canadian traditions which might occur at a Toronto wedding, especially if the bride and groom are wanting to experience a little bit of history or culture with their wedding or the preparations leading up to it.
An old time a Toronto wedding tradition was the trousseau tea. This occurred long ago, when brides were considered to be dowry. The mother of the bride would host neighbors and acquaintances, usually those not invited to the actual wedding, at her house. During this time, the bride's personal possession, any shower or wedding gifts she received, and her hope chest would all be on display. Obviously this tradition is very out dated and mostly obsolete as arranged marriages aren't the norm of Toronto society. However, a few do still have wedding and bridal showers hosted by the bride's mom that are similar to trousseau teas, where some of the bride's most important possessions or gifts are on display.
Another tradition for Toronto weddings is a social. This is a public dance held in honor of the bride and groom before they get married. Admission tickets are sold to family and friends to get into the event, and a cash bar is available to allow guests to relax and have a good time dancing. Then the proceeds from the liquor and the cost to get into the social are given to the bride and groom. It is believed this helps them start their marriage.
One of the unique things about a Toronto wedding invitations is they sometimes will have the words 'presentation only' printed on them. This is a request by the couple for money as a wedding gift. It usually means they will accept money and nothing else, and it is considered inappropriate to show up with an actual gift.
Other traditions found in a Toronto wedding are the same traditions you find in American weddings. The family members of the bride sit on the left side of the church, while the groom's set on the right side. Brides traditionally wear a gown of white. A reception is traditionally held after the wedding ceremony to allow wedding guests to congratulate the couple. A cake is usually served at this reception, and the first piece of cake is usually cut by the bride and groom together to signal the unity in their marriage.
While there are some traditions that are unique to Canadian and Toronto weddings, most of the traditions are similar to those in America. Most variations in weddings in these two countries come from religious differences, not national heritage differences.
No matter what traditions are followed in a wedding, couples must remember that the most important thing is to do what makes them comfortable. Their wedding is about the two of them joining together as one, and they should only participate in the traditions that appeal to them.
