Wild Hogs Charity Dinner

Cornerstone Team enjoying the 70’s themed Disco Fever Night

In 2016, a “bunch” of motorcycle riding (not so) bad guys got together to continue the work of Deeds and Dreams. That work included hosting an annual dinner to raise some funds to help seriously, and sadly often terminally ill kids and their families, with the objective of providing quick and creative solutions where there was simply nowhere else to turn. This opportunity allows us to round up some friends and associates who want to give back to the community in a direct way, but without getting trapped up in the costly and cumbersome machinery that traditional charities often labour under.

Helping To Provide A Better Christmas For Five Families

Gifts in staging area for the over 70 families served this year.

Through the Caring & Sharing Program, the North Bramalea United Church community has brought Christmas to many families in need. The program started with six families and has grown to currently supporting 70 families. Cornerstone supports this initiative annually out of a desire to bring hope to families that need it during the Christmas season. Each year a dedicated team of volunteers call the families and determine their needs and wishes for a Happy Holiday season. Donations of cash or cheques to the church are turned into abundant blessings…….and used to spread the true spirit of Christmas to those who need it the most.
